Abstract
Description
Technical Field
[0001] The present invention relates to resistance of tomato (Solanum lycopersicum) plants, also known as tomatoes (Lycopersicumesculentum), to tobacco mosaic virus Tomato brown wrinkled fruit virus (ToBRFV, formerly abbreviated TBRFV). More specifically, the present invention relates to tomato plants and fruits comprising genetic determinants that lead to resistance to Tomato brown wrinkled fruit virus. According to the present invention, resistance is provided by a DNA sequence or QTL, which is introgressed from the S. pimpinellifolium gene into the genome of the S. lycopersicum plant on chromosome 9 or 11. The introgressed QTL on chromosome 9 can be present in the genome of the tomato plant homozygously or heterozygously. The introgressed QTL on chromosome 11 is preferably present in the genome of the tomato plant homozygously. The present invention also relates to a marker associated with the DNA sequence, and the use of this marker to identify or select the DNA sequence or QTL, and to identify or select plants carrying such resistance. The invention also relates to the seeds and progeny of such plants and propagation materials for obtaining such plants, as well as different uses of these plants. Background Art
[0002] All cultivated and commercial forms of tomatoes belong to the species most commonly known as Lycopersicon esculentum Miller. The genus Lycopersicon is a relatively small genus in the extremely large and diverse Solanaceae family, which is thought to consist of about 90 genera, including peppers, tobacco, and eggplant. The genus Lycopersicon has been divided into two subgenera, the esculentum complex, which contains those species that can be easily hybridized with commercial tomatoes, and the peruvianum complex, which contains those species that are difficult to hybridize (Stevens, M. and Rick, CM 1986). Due to its value as a crop, L. esculentum has spread widely throughout the world. Even though the exact origin of the cultivated tomato is unclear, it seems to have come from the Americas, native to Ecuador, Peru, and the Galapagos Islands, and was first cultivated by the Aztecs and Incas in 700 AD. Mexico seems to have been the earliest place of domestication and source of introduction. It is assumed that the cherry tomato (L. esculentum var. cerasiforme) is the direct ancestor of the modern cultivated form.
[0003] Tomatoes are grown for their fruit and are widely used for fresh market or processed products. As a crop, tomatoes are grown commercially whenever environmental conditions allow for economically viable yields. Most fresh market tomatoes are hand-picked at the green ripe stage on the vine. Fresh market tomatoes are available year-round. Processing tomatoes are mostly mechanically harvested and used in a variety of forms such as canned tomatoes, tomato juice, tomato sauce, puree, tomato paste or even tomato sauce.
[0004] Tomatoes are generally a simple diploid species with twelve pairs of differentiated chromosomes. However, polyploid tomatoes are also part of this invention. Cultivated tomatoes are self-pollinating, almost completely self-pollinating. Tomato flowers are hermaphroditic. Commercial cultivars were originally open-pollinated. As heterosis has been identified in tomatoes, hybrids are replacing open-pollinated varieties due to their increasing popularity among farmers due to higher yields and more uniform plant characteristics. Due to their wide spread and high value, tomatoes have been intensively cultivated. This explains why there is such a wide range of tomato varieties today. Shapes range from small to large, and there are cherry, plum, pear, nubby, round and beefsteak types. Tomatoes can be grouped according to the time it takes for the plant to mature fruit for harvest, and generally speaking, cultivars are considered early, mid-ripening or late-ripening. Tomatoes can also be grouped according to the growth habit of the plant; grouped as determinate, semi-determinate or indeterminate. Determinate plants tend to produce foliage first, then flowers, which ripen into fruit if pollination is successful. All fruits tend to mature on the plant at about the same time. Indeterminate tomatoes start out with some foliage, then continue to produce foliage and flowers throughout the growing season. At any given time, these plants tend to have tomatoes at various stages of maturity. Semi-determinate tomatoes have a phenotype somewhere in between determinate and indeterminate, and they are typically determinate, except that they grow larger than determinate varieties. Recent developments in tomato breeding have resulted in a wider variety of fruit colors. In addition to the standard red ripening color, tomatoes can also be creamy white, lime green, pink, yellow, gold, orange, or purple.
[0005] Hybrid commercial tomato seeds can be produced by artificial pollination. Pollen from the male parent is harvested and applied manually to the stigma surface of the female inbred line. Flowers are covered before and after artificial pollination so that insects do not bring in foreign pollen and create a mixture or impurity. Flowers are marked to identify the pollinated fruit, from which seeds are harvested.
[0006] A variety of pathogens affect the productivity of tomato plants, including viruses, fungi, bacteria, nematodes and insects. Tomato is particularly susceptible to many viruses, so virus resistance is of great agricultural importance.
[0007] Tobacco mosaic virus is one of the most important plant viruses causing serious damage in agriculture, especially to vegetable and ornamental crops worldwide. Tobacco mosaic virus is easily spread mechanically, as well as via seeds. The general characteristics of tobacco mosaic virus are rod-shaped particles of about 300 nm encapsulating a single-stranded positive RNA genome encoding four proteins. In tomatoes, tobacco mosaic virus (TMV) and tomato mosaic virus (ToMV) are feared by growers worldwide, as they can severely damage crop production, for example through irregular ripening (yellow spots on the surface of the fruit and brown spots below the surface). However, plant breeders have identified multiple genes over the years, and resistant tomato varieties for TMV and / or ToMV now exist.
[0008] All modern indeterminate tomato varieties and many determinate tomato varieties developed over the past few decades do contain the Tm-2 gene or preferably a Tm-2 variant of the gene. 2 alleles, which made them immune to almost all tobacco mosaic virus species (ToMV and TMV) known to affect commercial tomatoes before 2014.
[0009] During 2014-2015, severe virus outbreaks affected tomato producing areas in the Middle East, such as Jordan and Israel. Most affected tomato varieties are considered to be resistant to TMV and / or ToMV, but are still severely affected and show typical TMV / ToMV-like symptoms: although the symptoms of branches and leaves are very similar to those of TMV / ToMV, the fruit symptoms are more frequent and severe than the common symptoms of such viruses with fruit lesions and deformations. The fruit quality is very poor and it is quite difficult to sell. Salem et al. (Arch. Virol. 161 (2), 503-506. 2015) extracted RNA from the fruits and leaves of symptomatic plants infected in Jordan and performed various tests, ultimately identifying a new species of tobacco mosaic virus, whose sequence corresponds to GenBank accession number KT383474 (SEQ ID NO: 112); Salem et al. proposed to name this Jordan virus: Tomato Brown Wrinkled Fruit Virus (formerly TBRFV, now ToBRFV). Comparison with other tobacco mosaic virus sequences showed that ToBRFV is indeed a tobacco mosaic virus, but not TMV or ToMV. Resistance to TMV and / or ToMV does not confer resistance to this new virus, ToBRFV.
[0010] Luria et al. (PLoS One. 2017; 12(1): e0170429) simultaneously isolated and sequenced the complete genome of the Israeli tobacco mosaic virus that infects tomatoes in Israel, corresponding to GenBank accession number KX619418 (SEQ ID NO: 113). As a result, they showed very high sequence identity (more than 99% sequence identity) between the Israeli virus and the Jordan virus and concluded that they were two different isolates of the tomato brown wrinkle fruit virus.
[0011] Recently, the virus has been detected in Europe, particularly in Sicily, Germany, the Netherlands and France, as well as in Mexico, so it is now considered a major global threat to tomato crops. The strains identified appear to be essentially Israeli strains, not Jordanian ones.
[0012] The identification of tomato plants showing resistance to Tomato Brown Ruffled Fruit Virus and the localization and identification of genetic determinants, hereinafter also referred to as QTLs (Quantitative Trait Loci) leading to resistance to Tomato Brown Ruffled Fruit Virus, was recently described in WO2018 / 219941, although tolerance is mentioned in this publication. Two QTLs, namely QTL1 and QTL2, were found on chromosomes 6 and 9, respectively, and when homozygous appeared in a tomato background, independently or in combination, conferred improved tolerance or resistance to the fruits of tomato plants infected or potentially infected with ToBRFV. A third QTL, QTL3, was found on chromosome 11 and, when homozygous appeared, it conferred improved tolerance or resistance to the leaves of tomato plants infected or potentially infected with ToBRFV.
[0013] Although these QTLs, alone or in combination, provide tolerance or resistance to ToBRFV, the inventors have now determined that in most cases they do not confer a high enough level of resistance on tomato plants such that a significant portion of the fruit is affected and cannot be marketed. Furthermore, these QTLs are described as conferring resistance when present in homozygous form. As long as QTL2 on chromosome 9 is present in the presence of a Tm-2 2 Genetically identical loci, in regions that are usually transmitted “en bloc” without recombination, therefore this QTL on chromosome 9 is not suitable for Tm-2 2 Gene binding.
[0014] WO2019 / 110130 and WO2019 / 110821 disclose the identification of 3 different QTLs on chromosomes 6, 11 and 12 that were introgressed from currant tomatoes and allegedly confer resistance or tolerance to ToBRFV. However, the QTL on chromosome 11 is described as being located between 2 markers that define a 55 Mb region corresponding to almost the entire sequence of chromosome 11. Without any more explicit description, this QTL on chromosome 11 cannot be used for genetic introgression.
[0015] WO2020 / 018783 discloses a genetic region on chromosome 11 of tomato, which contains a Stemphylium resistance allele from currant tomato and is also said to contain a related ToBRFV resistance allele. Since both alleles are associated with the same marker according to the disclosure of this document, it is not possible to introgress only ToBRFV resistance, especially in plants that are already resistant to Stemphylium but susceptible to ToBRFV.
[0016] Since tobacco mosaic virus is not easily controlled but rather genetically improved through identification and use in breeding of resistance genes, and since currently available resistance genes for control of TMV and / or ToMV are not useful against the new tomato brown wrinkled fruit virus damage, and the tolerance or resistance QTLs that have been identified are not always sufficiently effective, are not well characterized and cannot be used in conjunction with Tm-2 2 Combined, there is an urgent need to identify resistance to this new tobacco mosaic virus, as failure to do so will result in entire regions no longer being able to produce tomato crops. Summary of the invention
[0017] The inventors have identified resistance to ToBRFV in wild-type S. pimpinellifolium plants and have been able to introgress this resistance gene into S. lycopersicum plants, thereby obtaining tomato (S. lycopersicum) plants resistant to ToBRFV. The resistance of the present invention is conferred by a newly discovered sequence that is linked to an additive quantitative trait locus (QTL) and is transferable to different tomato genetic backgrounds.
[0018] The newly discovered QTLs confer resistance to Tomato Brown Rugose Fruit Virus (ToBRFV) essentially at the fruit level of virus-infected tomato plants, for the QTL on chromosome 9 at the leaf level of virus-infected tomato plants, and for the QTL on chromosome 11 essentially at the leaf level of infected plants.
[0019] Therefore, the present invention provides these introgressed sequences, also referred to herein as QTLs, which confer a ToBRFV resistance phenotype at the tomato leaf and / or fruit level in tomato plants infected with ToBRFV.
[0020] The present invention provides tomato plants showing resistance to ToBRFV, including commercial plants, strains and hybrids, and methods for producing or identifying tomato plants or populations (germplasm) showing resistance to ToBRFV. The present invention also discloses molecular genetic markers, especially single nucleotide polymorphisms (SNPs), which are linked to the QTLs responsible for ToBRFV resistance of the present invention. Plants obtained by methods and uses of these molecular markers are also provided.
[0021] Furthermore, the resistance can be easily transferred to different genetic backgrounds, ie into tomato varieties, and the invention also extends to different methods allowing the transfer or introgression of QTLs conferring a phenotype.
[0022] The present invention also provides various methods and uses of information associated with these SNPs associated with QTLs that confer ToBRFV resistance, in particular methods for identifying ToBRFV-resistant plants and methods for identifying further molecular markers associated with such resistance, as well as methods for improving tomato yield in an environment infected by ToBRFV and methods for protecting tomato fields from ToBRFV infection.
[0023] definition:
[0024] The term "resistance" is defined by the ISF (International Seed Federation) Vegetable and Ornamental Crops Section to describe plant responses to pests or pathogens, and abiotic stresses in the vegetable seed industry. Specifically, resistance refers to the ability of a plant variety to limit the growth and development of a specific pest or pathogen and / or the damage they cause, compared to susceptible plant varieties under similar environmental conditions and pest or pathogen pressure. Resistant varieties may show some disease symptoms or damage under severe pest or pathogen pressure. Two levels of resistance are defined:
[0025] Highly resistant (HR): Plants that highly restrict the growth and / or development of a specific pest and / or the damage it causes under normal pest pressure, compared to susceptible plants. However, these plants may show some symptoms or damage under severe pest pressure.
[0026] Intermediately Resistant (IR): Plants that highly restrict the growth and / or development of a specific pest and / or the damage it causes, but may show a wider range of symptoms or damage than highly resistant plants. When grown under similar environmental conditions and / or pest pressure, intermediately resistant plants will still show less severe symptoms or damage than susceptible plants.
[0027] The term tolerance is often used to describe the ability of plants to withstand abiotic stress without severe consequences for growth, appearance, and yield.
[0028] However, in the literature and patents, the term is also used to refer to the phenotype of a plant, in which at least some disease symptoms remain absent when the plant is exposed to an infectious dose of the virus, whereby systemic or local infection, viral propagation, and at least under certain culture conditions, at least the presence of viral genomic sequences in the plant cells and / or their genomic integration can be determined. Thus, tolerant plants are resistant to symptomatic manifestations but asymptomatic to virus carriers. Sometimes, viral sequences can be present or even propagated in plants without causing disease symptoms. It should be understood that tolerant plants, although infected by viruses, are generally able to at least moderately restrict the growth and development of the virus.
[0029] For this reason, tolerant plants according to this definition are best characterized as moderately resistant plants.
[0030] In the case of ToBRFV, leaf resistance or foliar resistance refers to a phenotype of a plant in which disease symptoms on leaves remain absent or less pronounced when the plant is exposed to an infectious dose of ToBRFV. However, disease symptoms on fruit may appear on infected plants.
[0031] In the case of ToBRFV, fruit resistance refers to the phenotype of a plant in which disease symptoms on the fruit remain absent or less pronounced when the plant is exposed to an infectious dose of ToBRFV. However, disease symptoms on the leaves may appear on infected plants.
[0032] Symptoms on leaves infected with ToBRFV usually include mosaic, deformed leaflets, and in many cases webbing. Symptoms on fruit infected with ToBRFV usually include the typical yellow lesions (discoloration) and deformed fruit. In many cases, there are also "chocolate spots" on the fruit.
[0033] Susceptibility: The inability of the plant to restrict the growth and development of a specific pest or pathogen; susceptible plants display deleterious symptoms associated with viral infection, i.e. foliage damage and fruit damage in the case of ToBRFV infection.
[0034] Tomato plants susceptible to TBRFV, such as the commercial variety Candela mentioned in the publication by Salem et al., 2015.
[0035] To date, i.e. prior to the present invention, all commercially available tomato varieties grown in ToBRFV-infected areas were susceptible to ToBRFV or did not have sufficient resistance for those plants carrying tolerance QTLs, such as the deposited seeds of HAZTBRFVRES1 mentioned in PCT application WO2018 / 219941.
[0036] Thus, the plants according to the invention have at least improved resistance or tolerance to ToBRFV relative to the variety Candela and more generally relative to any commercial tomato variety grown in ToBRFV-infected areas, including tolerant plants, and relative to HAZTBRFVRES1. The improved resistance relative to the plants corresponding to HAZTBRFVRES1 is demonstrated in Example 5 of the experimental part.
[0037] As used herein, the term "offspring" or "progeny" refers to any plant produced as progeny by asexual or sexual reproduction from one or more parent plants or their progeny. For example, progeny plants can be obtained by cloning or selfing of parent plants, or by crossing two parent plants, and include selfing and F1 or F2 or further generations. F1 is the first generation of offspring produced by parents, wherein at least one parent is the donor used as a trait for the first time, and the offspring of the second generation (F2) or subsequent generations (F3, F4, etc.) are samples produced from selfing, such as F1', F2', etc. Therefore, F1 can be (and usually is) a hybrid produced by crossing two true genetic parents (true genetics is homozygous for traits), and F2 can be (and usually is) an offspring produced by self-pollination of the F1 hybrid.
[0038] As used herein, the terms "hybridization," "hybridized," "cross-pollination," or "cross breeding" refer to the process of applying pollen from one flower on one plant (artificially or naturally) to the ovules (stigma) of a flower on another plant.
[0039] As used herein, the term "genetic determinant" and / or "QTL" refers to any DNA fragment associated with a biological function. Thus, QTL and / or genetic determinant include, but are not limited to, genes, coding sequences, and / or regulatory sequences required for their expression. QTL and / or genetic determinant may also include non-expressed DNA fragments, for example, recognition sequences that form other proteins.
[0040] As used herein, the term "genotype" refers to the genetic makeup of a single cell, cell culture, tissue, organism (eg, plant), or population of organisms.
[0041] As used herein, the term "grafting" is the operation of grafting a rootstock to a scion. The main motivation for grafting is to avoid damage caused by soil-borne pests and pathogens when genetic or chemical methods of disease management are not available. Grafting a susceptible scion onto a resistant rootstock can provide a resistant cultivar without breeding resistance into the cultivar. In addition, grafting can enhance tolerance to abiotic stresses, increase yields and lead to more efficient water and nutrient use.
[0042] As used herein, the term "heterozygous" refers to a diploid or polyploid individual cell or plant that has different alleles (forms of a given gene, genetic determinant, or sequence) present at least at one locus.
[0043] As used herein, the term "heterozygous" refers to the presence of different alleles (forms of a given gene, genetic determinant, or sequence) at a particular locus.
[0044] As used herein, "homologous chromosomes" or "homologs" (or homologs) refer to a set of one maternal chromosome and one paternal chromosome that pair with each other during meiosis. These copies have the same type of genes at the same locus and the same centromere position, but their sequences or alleles may be different.
[0045] As used herein, the term "homozygous" refers to an individual cell or plant that has the same alleles at one or more loci on all homologous chromosomes.
[0046] As used herein, the term "homozygous" refers to the presence of identical alleles at one or more loci in homologous chromosome segments.
[0047] As used herein, the term "hybrid" refers to any individual cell, tissue, or plant produced by a cross between parents that differ in one or more genes.
[0048] As used herein, the term "locus" (plural: "loci") refers to any genetically defined site, which can be a single position (nucleotide) or a chromosomal region. A locus can be a gene, a genetic determinant, a portion of a gene, or a DNA sequence, and can be occupied by different sequences. A site can also be defined by a SNP (single nucleotide polymorphism), multiple SNPs, or two flanking SNPs.
[0049] As used herein, the term "rhizome" is the lower part of the plant that is capable of receiving the scion in the grafting process.
[0050] As used herein, the term "scion" is the taller part of a plant that can be grafted onto a rhizome in a grafting process.
[0051] The present invention includes plants of different ploidy levels, primarily diploid plants, but also triploid plants, tetraploid plants, etc.
[0052] In the context of the present invention, DNA strands and alleles are designed as TOP according to the TOP / BOT designation method developed by Illumina:
[0053] (https: / / www.illumina.com / documents / products / technotes / technote_topbot.p df). DETAILED DESCRIPTION
[0054] The present inventors have identified QTLs which, when present alone or in combination in tomato plants, provide improved resistance in fruits and / or leaves of tomato plants infected or potentially infected with Tomato Brown Ruffle Fruit Virus (ToBRFV).
[0055] The inventors have identified a major QTL on chromosome 9, hereinafter referred to as QTL9, which, when present in a tomato background, confers resistance to ToBRFV infection, especially fruit resistance; and another additive QTL on chromosome 11, hereinafter referred to as QTL11, which also confers resistance to ToBRFV, especially leaf resistance, and can be combined with QTL9 defined above.
[0056] Seeds and plants according to the invention have been obtained from initial crosses between wild plants of S. cerevisiae (the introgression partner showing the desired phenotype but in another species) and tomato plants (the recurrent susceptible parent) in order to transfer the resistance into the tomato genetic background.
[0057] Seeds of resistant tomato plants derived from this initial cross homozygously contain QTL9 and QTL11 and are called LVSTBRFVRES2 and have been deposited by the inventors with NCIMB on April 1, 2020, with the deposit number NCIMB 43591. Plants grown from these deposited seeds are tomatoes (S. lycopersicum) that are resistant to ToBRFV, i.e., show at least improved fruit resistance to the virus relative to any known tomato plants, in particular any commercial tomato plants.
[0058] As shown in the examples, the phenotype of the plant according to the invention is best characterized as resistance to ToBRFV rather than tolerance, i.e. fruit resistance or foliage and fruit resistance, tolerance only being applicable to abiotic stress. Tolerance is also widely used to characterize resistance or moderate resistance, however, the plants of the invention may also be characterized as tolerant plants. In the following, reference is made to resistance to ToBRFV; however, this phenotype includes a tolerant phenotype, as defined in certain publications, as well as intermediate resistance.
[0059] In addition, as also demonstrated in the examples, in particular in Examples 4, 5 and 8, the ToBRFV resistance according to the present invention is different from the tolerance / resistance disclosed in the prior art. In fact, Example 5 demonstrates that the level of resistance according to the present invention is higher than the level of resistance described in WO2018 / 219941. In addition, Example 4 demonstrates that the sequences responsible for ToBRFV resistance according to the present invention and according to WO2018 / 219941 are different. Example 8 demonstrates that the ToBRFV resistance according to the present invention is not related to resistance to Stolonifera, contrary to the genetic determinants disclosed in WO2020 / 018783, and is therefore different from this resistance.
[0060] Therefore, according to a first aspect, the present invention relates to a tomato plant comprising in its genome a QTL on chromosome 9, hereinafter referred to as QTL9, and / or a QTL on chromosome 11, hereinafter referred to as QTL11, conferring improved resistance to ToBRFV in the event of infection, in particular at the fruit level for QTL9 and at the branch and leaf level for QTL11; as well as seeds and cells of such a tomato plant comprising QTL9 and / or QTL11 in their genome.
[0061] Said QTL conferring resistance was originally introgressed from wild currant tomato genes and is therefore hereinafter referred to as resistance QTL, or QTL9 or QTL11, or introgression sequences of the invention. The invention also relates to cells of such plants or seeds comprising these resistance conferring introgression sequences.
[0062] The tolerance / resistance phenotype can be tested and scored as described in the experimental part, in particular in Example 1, by natural infection or by artificial inoculation, either at the first leaf level or at the fruit level.
[0063] The QTL conferring improved resistance to ToBRFV is preferably located within the chromosomal interval or region defined by SNP TO-0201220 (SEQ ID NO. 1) and the SNP having SEQ ID NO. 101 on chromosome 9.
[0064] Indeed, the inventors have demonstrated in the Examples section that the introgressed sequence corresponding to QTL9 in this region is inherited along with the phenotype of interest.
[0065] According to the present invention and the QTL9 that confers improved resistance to ToBRFV is selected from the QTL9 present in the LVSTBRFVRES2 seed genome. Therefore, QTL9 is present in the genome of these deposited seeds. Samples of these tomato seeds have been deposited by HM.Clause SA (rue Louis Saillant, 26800 Portes-les-Valence, France), according to and meet the requirements of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for Patent Procedure ("Budapest Treaty"), and were deposited in the National Collection of Industrial, Food and Marine Microorganisms (NCIMB) (NCIMB, Ltd, Ferguson Building, Craibstone Estate, Bucksburn, Aberdeen AB21 9YA, UK) on April 1, 2020 with a deposit number of 43591. The deposit of this tomato seed is preserved by HM.Clause SA (rue Louis Saillant, 26800 Portes-les-Valence, France).
[0066] Other QTLs that confer improved resistance to ToBRFV according to the present invention are preferably located on chromosome 11, within the chromosomal interval or region defined by SNP TO-0201237 (SEQ ID NO: 102) and SL2.50ch11_9924232 (SEQ ID NO: 115), preferably within the chromosomal interval or region defined by SNP TO-0201237 (SEQ ID NO: 102) and SNP TO-0201241 (SEQ ID NO: 106). QTL11 according to the present invention and conferring improved resistance to ToBRFV, can be combined with QTL9, selected from those present in the genome of seeds of LVSTBRFVRES2, NCIMB 43591. QTL11 is indeed present in the genome of seeds of LVSTBRFVRES2 NCIMB, deposit number 43591.
[0067] The specific polymorphisms corresponding to the SNPs (single nucleotide polymorphisms) or markers mentioned in this specification, as well as the flanking sequences of these SNPs or markers in the tomato genome, are given in the experimental part (see in particular Tables G and H for QTL9, and Table K for QTL11) and in the accompanying sequence listing. Their positions relative to the tomato genome version 2.50 on chromosomes 9 and 11, as well as their flanking sequences are also indicated.
[0068] In this regard it is to be noted that, by definition, a SNP refers to a single nucleotide in the genome which varies depending on the allele present, whereas the flanking nucleotides are identical. In order to facilitate clear identification of the positions of the different SNPs, their positions are given in Tables G, H and K, identified by SEQ ID numbers by reference to the tomato genome sequence in version 2.50 thereof and by reference to their flanking sequences. In a sequence associated with a particular SNP in the present application, for example SEQ ID NO:1 for SNP TO-0201220, only one nucleotide in the sequence actually corresponds to the polymorphism, i.e. the 201st nucleotide of SEQ ID NO:1 corresponds to the polymorphic position of SNP TO-0201220, which may be either A or G as shown in Table G. The flanking sequences are used to locate the SNP in the genome, but are not part of the polymorphism itself. Therefore, detecting a SNP marker or an allele of that SNP refers to detecting the polymorphic nucleotide of that marker, and it is not necessary that all flanking sequences are identical.
[0069] Similarly, the other markers mentioned in the specification and Table K are not SNPs strictly speaking, but INDEL markers, which cause a single nucleotide insertion. For example, for the marker SL2.50ch11_9684449 (SEQ ID NO: 112) at position 9684449 of SL2.50 according to Table K, this means that position 9684449 is an allele, i.e., C or CT, corresponding to an insertion of T. The position of "C" in SL2.50 is the position 9684449 mentioned in Table K. As long as the allele only involves one position of these INDEL markers, for simplicity, they may also be referred to as SNP markers by language extension in the following.
[0070] The genomic or chromosomal region identified by the flanking sequence, such as a SNP or INDEL marker (hereinafter referred to as SNP) is thus clearly and unambiguously defined.
[0071] The genomic region defined by two SNPs X and Y refers to the portion of the genome, more specifically the portion of the chromosome, located between the positions of the two SNPs, preferably including the SNPs, so that the nucleotide sequence of this chromosomal region starts with the nucleotide corresponding to SNP X and ends with the nucleotide corresponding to SNP Y, i.e. according to the present invention, the SNPs are contained in the region defined by them.
[0072] By "introgression sequence from Solanum cerevisiae" in a given genomic region, it is understood that the genomic sequence found in this region has the same sequence as the corresponding genomic sequence found in the Solanum cerevisiae donor, i.e., in the introgression partner, is located at the same locus and has the same sequence as the corresponding genomic sequence found in LVSTBRFVRES2 (NCIMB 43591) at the same locus. By "having the same sequence", it is meant that the two sequences being compared are identical, except for potential point mutations that may have occurred during the transmission of the genomic region to the progeny, i.e., preferably at least 99% identical over a length of 1 kb.
[0073] It can be concluded that, in the sense of the present invention, a given genomic region has the same sequence as the corresponding genomic region found in a C. solanum donor of the same locus if said genomic region is also capable of conferring resistance to ToBRFV and originates from C. solanum.
[0074] For example, the presence of introgressed sequences in the genome of a tomato plant, seed or cell can be shown by GISH (Genetic In Situ Hybridization). GISH is indeed a powerful technique for detecting the introgression of chromatin material from one species or subspecies into another. The advantage of GISH is that the introgression process is visualized by means of a "genomic picture of introgression". Using this technique, it is also possible to determine whether a specific region of the genome is homozygous or heterozygous, thanks to the use of codominant molecular cytogenetic markers. With this technique, it is also possible to determine in which chromosome the introgressed gene of interest is present.
[0075] The present inventors have identified and located the QTLs that confer ToBRFV resistance of the present invention, mainly by identifying the presence of sequences representing QTLs of gene introgression at different loci along the above-mentioned chromosome 9 and 11 regions, i.e., 101 different loci defined by 101 SNPs of SEQ ID NO.1 to 101 with QTL9, and 14 different loci defined by 14 markers of SEQ ID NO: 102 to 115 with QTL11. These SNPs are hereinafter referred to as the SNPs of the present invention, or the 101 SNPs of the present invention for QTL9. Among them, the preferred SNPs are the 14 SNPs with SEQ ID NO: 1 to 14; in particular, the SNPs with SEQ ID NO: 1, 2, 10, 12 and 14.
[0076] Therefore, in the genome of the plant, seed or cell of the present invention, the presence of introgressed sequences or QTLs that confer a resistance phenotype can be identified based on these SNP markers.
[0077] Preferably, for QTL9, one of the 101 SNPs having SEQ ID NOs: 1-101 is used, and preferably one selected from the group consisting of SNPs TO-0201220 (SEQ ID NO: 1), TO-0201221 (SEQ ID NO: 2), TO-0201222 (SEQ ID NO: 3), TO-0201223 (SEQ ID NO: 4), TO-0201224 (SEQ ID NO: 5), TO-0201225 (SEQ ID NO: 6), TO-0201226 (SEQ ID NO: 7), TO-0201227 (SEQ ID NO: 8), TO-0201228 (SEQ ID NO: 9), TO-0201229 (SEQ ID NO: 10), TO-0201230 (SEQ ID NO: 11), TO-0201231 (SEQ ID NO: 12), TO-0201232 (SEQ ID NO: 13), The presence of the gene introgressed sequence or QTL in tomato plants is identified or characterized by a SNP from a list of 14 SNPs of TO-0201220, TO-0201221, TO-0201229, TO-0201231 and TO-0201233. The QTL9 of the present invention can be identified or characterized, for example, by SNP TO-0201220 or SNP TO-0201229.
[0078] Another suitable SNP is one having SEQ ID NO: 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26; 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58 , 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 and 101.
[0079] According to a preferred embodiment, for QTL9, the presence of the introgressed sequence in the tomato plant, cell or seed of the present invention is identifiable by at least 2, preferably at least 3, or at least 5 of the 101 SNP markers, or the 14 SNP markers, preferably at least one of which is SNP TO-0201220 or SNP TO-0201229. For example, the presence of the introgressed sequence conferring resistance to ToBRFV is detected by the presence of a haploid consisting of at least 2 SNPs, for example one SNP is TO-0201229 and the other SNP is a different SNP selected from the SNPs having SEQ ID NO: 1-101 (excluding SEQ ID NO: 10).
[0080] For the 101 SNPs of the present invention, the alleles of these molecular markers representing the QTLs or gene introgression sequences conferring the resistance of the present invention are reported in the last column of Table H. For the above 14 SNP markers, the alleles representing the gene introgression QTL are SNPs allele G of TO-0201220, allele G of TO-0201221, allele A of TO-0201222, allele A of TO-0201223, allele A of TO-0201224, allele A of TO-0201225, allele A of TO-0201226, allele C of TO-0201227, allele C of TO-0201228, allele A of TO-0201229, allele C of TO-0201230, allele C of TO-0201231, allele G of TO-020132 and allele G of TO-020133.
[0081] Thus, the presence of a QTL in the genome of a tomato plant, cell or seed according to the invention can be detected or revealed by detecting a sequence representing the QTL at said locus, more preferably by detecting one or more resistance alleles of a SNP having SEQ ID NOs: 1-101, as reported in the last column of Table H, for example, by detecting allele G of SNP TO-0201220, allele G of TO-0201221, allele A of TO-0201222, allele A of TO-0201223, allele A of TO-0201224, allele A of TO-0201225. A, allele A of TO-0201226, allele C of TO-0201227, allele C of TO-0201228, allele A of TO-0201229, allele C of TO-0201230, allele C of TO-0201231, allele G of TO-0201232, and allele G of TO-0201233, more preferably by detecting SNP Allele G of TO-0201220, allele G of SEQ ID TO-0201221, allele A of TO-0201229, allele C of TO-0201231 or allele G of TO-0201233, and even more preferably detected or revealed by detecting SNP allele G of TO-0201220 and / or allele A of TO-0201229.
[0082] According to a preferred embodiment, the QTL on chromosome 9 of the present invention, i.e., QTL9, is detected in the genome of a tomato plant, cell or seed by detecting at least 2, preferably 3, and preferably at least 5 resistance alleles of SNPs with SEQ ID NOs: 1 to 101, preferably at least one detected resistance allele is allele G of SNP TO-0201220 and / or allele A of TO-0201229.
[0083] QTL9 is located on a chromosomal interval of chromosome 9 defined or flanked on one side by the flanking SNP TO-0201220 and on the other side by the flanking SNP marker having SEQ ID NO. 101. A more preferred chromosomal interval of chromosome 9 where QTL9 is found is the interval defined by TO-0201220 and TO-0201233. A more preferred interval is an interval defined by SNPs having SEQ ID NO: 20 and TO-0201233, or an interval between SNPs having SEQ ID NO: 22 and TO-0201233, or an interval between SNPs having SEQ ID NO: 26 and TO-0201233, or an interval between SNPs having SEQ ID NO: 30 and TO-0201233, or an interval between SNPs having SEQ ID NO: 34 and TO-0201233, or an interval between SNPs having SEQ ID NO: 38 and TO-0201233, or preferably an interval between SNPs TO-0201221 and TO-0201233.
[0084] QTL11 according to the present invention is preferably detected by one of the markers with SEQ ID NOs: 102 to 115, preferably by one of the SNP markers with SEQ ID NOs: 102 to 111, preferably by at least one of SNPs TO-0201237 (SEQ ID NO: 102), TO-0201238 (SEQ ID NO: 103), TO-0201239 (SEQ ID NO: 104), TO-0201240 (SEQ ID NO: 105) and TO-0201241 (SEQ ID NO: 106), and / or by markers SL2.50ch11_9684449 (SEQ ID NO: 112), SL2.50ch11_9779896 (SEQ ID NO: 113), SL2.50ch11_9823405 (SEQ ID NO: 114). Preferably, the presence of the QTL11 can be characterized by detecting one of the resistance alleles of the markers with SEQ ID NOs: 102 to 115, preferably by characterizing one of the resistance alleles of the SNPs with SEQ ID NOs: 102 to 111 and / or one of the markers with SEQ ID NOs: 112 to 115, as disclosed in the last column of Table K. According to a preferred embodiment, the presence of QTL11 is detected by detecting at least one of the alleles CT of SL2.50ch11_9684449, the allele AT of SL2.50ch11_9779896, the allele C of SL2.50ch11_9823405, the allele GT of SL2.50ch11_9924232, the allele G of TO-0201237, the allele A of TO-0201238, the allele A of TO-0201239, the allele A of TO-0201240 and the allele A of TO-0201241. Individual characterizations, preferably characterized by at least one of allele G of TO-0201237, allele A of TO-0201238, allele A of TO-0201239, allele A of TO-0201240 and allele A of TO-0201241, and / or at least one of allele CT of SL2.50ch11_9684449, allele AT of SL2.50ch11_9779896, allele C of SL2.50ch11_9823405 and allele GT of SL2.50ch11_9924232.Thus, preferred markers for QTLH are those with SEQ ID NOs: 102 to 115 (Table K), or those with SEQ ID NOs: 102-111, or the sequence of markers TO-0201237, TO-0201238, TO-0201239, TO-0201240, TO-0201241, SL2.50ch11_9684449, SL2.50ch11_9779896, SL2.50ch11_9823405 and SL2.50ch11_9924232. Table K, or a list of markers TO-0201237, TO-0201238, TO-0201239, TO-0201240 and TO-0201241, or a list of markers SL2.50ch11_9684449, SL2.50ch11_9779896, SL2.50ch11_9823405 and SL2.50ch11_9924232. Preferred resistance alleles are those corresponding to these different lists and given in Table K. These lists of markers and / or resistance alleles are applicable to all different aspects of the invention.
[0085] The tomato plants, cells or seeds of the present invention may be homozygous for QTL9, QTL11 or the introgression sequence of the present invention that confers ToBRFV resistance. However, the present invention is not limited to such homozygous plants, cells or seeds. In fact, the inventors have also demonstrated that the resistance conferred by such QTL9 is additive, and that such plants heterozygous for the QTL9 of the present invention are also resistant to ToBRFV (see the experimental section), with a resistance level lower than that of plants homozygous for the QTL, but higher than that of susceptible plants. Therefore, the present invention also includes tomato (S. lycopersicum) plants, cells or seeds of the present invention that heterozygously possess QTL9 or a gene introgression sequence in their genome on chromosome 9 as defined above.
[0086] QTL11 may also be present homozygously or heterozygously in a tomato plant, cell or seed of the invention, but only confers ToBRFV resistance at the homozygous stage, since the resistance allele is recessive (see Example 9 in this regard). The heterozygous or homozygous presence of QTL9 and QTL11 can be defined independently.
[0087] According to a preferred embodiment, the plant, seed or cell of the invention comprises QTL9 heterozygously or homozygously, and QTL11 homozygously or heterozygously as defined above. Preferred combinations are the presence of both QTL9 and QTL11 homozygously, QTL9 heterozygously with QTL11 homozygously, and the presence of both QTLs heterozygously.
[0088] Preferably, the tomato plant according to the invention is a commercial plant or line. Such commercial plants or lines preferably also show resistance to ToMV (Tomato Mosaic Virus), for example due to the presence of the Tm-2 gene (allele Tm-2 or Tm-2 2 (also known as Tm-2a)), which also confers resistance to TMV (Tobacco Mosaic Virus). Plants according to this aspect of the invention preferably also have the following additional characteristics: nematode resistance traits (Mi-1 or Mi-j), and resistance to Fusarium and Verticillium, and TYLCV resistance.
[0089] Other resistances or tolerances are also contemplated according to the present invention.
[0090] According to a preferred embodiment, the plant of the present invention has no resistance to Pepino Mosaic Virus (PepMV). According to another embodiment, the tomato plant of the present invention also has resistance to PepMV.
[0091] Furthermore, the commercial plants of the invention bear fruit under suitable conditions of at least 10 g, preferably 25 g when fully mature, preferably at least 100 g when fully mature, and / or even more preferably at least 150 g or at least 200 g when fully mature. Furthermore, the number of fruits per plant is not substantially affected by the presence of the QTL9 of the invention, i.e. the productivity of the plants according to the invention is not inferior by more than 20% to plants having the same genotype but lacking said QTL9. Thus, the plants of the invention, e.g. plants grown from deposited seeds, generally bear at least 3 tomatoes per cluster, preferably about 4, and these fruits have a weight of preferably 150 to 180 g.
[0092] According to still another embodiment, the plant of the present invention is a determinate, indeterminate or semi-indeterminate plant or a seed or a cell thereof, ie corresponds to a determinate, indeterminate or semi-indeterminate growth habit.
[0093] By determinate, it refers to tomato plants that tend to produce foliage first, then flowers, which ripen into fruit if pollination is successful. All the fruit tend to ripen on the plant at about the same time. Indeterminate tomatoes start out by producing some foliage, then continue to produce foliage and flowers throughout the growing season. At any given time, these plants tend to have tomato fruit at various stages of ripeness. Semi-determinate tomatoes have a phenotype somewhere in between determinate and indeterminate, they are typically determinate except that they grow larger than determinate varieties.
[0094] The present invention also relates to a hybrid plant of tomatoes, which can be obtained by crossing a plant homozygous for the QTL9 of the present invention with another tomato. Since the QTL9 of the present invention is additive, the hybrid plant of tomatoes produced by the above hybridization will have resistance to ToBRFV. Preferably, the hybrid partner of the other tomato is free of the QTL9 described in the present invention, but may contain one of the QTLs described in WO2018 / 219941, preferably QTL2 on chromosome 9 or QTL3 on chromosome 11. Alternatively, the hybrid partner of the other tomato may contain the QTL on chromosome 11 that confers ToBRFV resistance described in WO2020 / 018783, WO2019 / 110130 and WO2019 / 110821.
[0095] The present invention therefore also relates to a tomato plant, seed or cell comprising homozygous or heterozygous the disclosed QTL9, and:
[0096] - QTL2 on chromosome 9 as disclosed in WO2018 / 219941; heterozygous;
[0097] - QTL3 on chromosome 11, as disclosed in WO2018 / 219941, preferably homozygously;
[0098] -One or more QTLs on chromosome 11, as disclosed in WO2020 / 018783, WO2019 / 110130 and WO2019 / 110821, homozygously or heterozygously.
[0099] In addition, with respect to the QTL on chromosome 11 that the inventors of the present invention have identified, hereinafter referred to as QTL11, which confers resistance to ToBRFV, this QTL11 can be present in combination with the QTL9 of the present invention. This QTL on chromosome 11 also corresponds to the sequence introgressed from the introgression partner of the currant tomato that provides QTL9. The sequence of the introgression corresponding to QTL11 was found in the region defined by SNP TO-0201237 (SEQ ID NO: 102) and SNP TO-0201241 (SEQ ID NO: 106) on chromosome 11. As demonstrated in the experimental part of the present application, this QTL11, when present in the genome of a tomato plant, in particular when present in combination with QTL9 in the genome of a tomato plant; provides increased resistance to ToBRFV relative to the same plant lacking said QTL11. Thus, each QTL independently confers resistance to ToBRFV, but the combination of QTLs provides increased resistance relative to the resistance provided by only one QTL, i.e. at least cumulative, in particular because the resistance of QTL11 is essentially at the leaf level and the resistance of QTL9 is at the fruit level. The present invention therefore also relates to tomato plants, cells and seeds comprising this QTL11 in their genome homozygously or heterozygously, but preferably homozygously so as to confer resistance to ToBRFV, preferably resistance to the leaves. Preferably, this QTL11 is found in combination with the QTL9 of the present invention.
[0100] Therefore, the present invention also relates to a tomato plant comprising QTL9 and QTL11, thereby increasing the plant's resistance level to ToBRFV relative to the corresponding plant lacking said QTL11; the present invention also includes cells and seeds thereof.
[0101] Furthermore, as disclosed above, the presence of resistance genes that provide resistance to ToMV and TMV is advantageous, especially for indeterminate commercial varieties. According to some preferred embodiments of the present invention, the Tm-2 that confers resistance to ToMV and TMV 2 The gene (also referred to as Tm-22 or Tm-2(2)) is thus combined with QTL9 of the present invention, with QTL11 of the present invention, or with QTL9 and QTL11. However, the inventors indicate that Tm-2 2 The gene and QTL9 are located on the same arm of chromosome 9, in the transmitted “en bloc” region, which is not prone to recombination events. 2 The combination of genes and QTL9 on the same chromosome 9 is difficult to obtain routinely. However, due to the Tm-2 2 The gene and QTL9 are dominant or at least cumulative, Tm-2 2The gene and QTL9 are advantageously found on two different homologues of chromosome 9, i.e. they are both present heterozygously. 2 The gene is preferably present heterozygously.
[0102] According to an embodiment, the present invention thus relates to a plant, cell or seed, which heterozygously comprises a QTL9 according to the present invention and a Tm-2 that provides resistance to ToMV and TMV. 2 gene or its analogue. 2 The gene is well known to those skilled in the art; suitable sequences of the gene are referred to as Solyc09g018220 or GeneBank AF536201, and the protein sequence is AAQ10736. Variants and analogs are well known in the art. According to a preferred embodiment, the Tm-2 2 The gene is a gene encoding a protein having the 861 amino acid sequence reported in AAQ10736 (SEQ ID NO: 114), or a gene having at least 75%, preferably at least 80% sequence identity with the sequence and exhibiting Tm-2 2 activity, i.e., the ability of a gene to inhibit viral RNA replication of a ToMV strain.
[0103] According to a preferred embodiment, the tomato plant, cell or seed of the present invention thus heterozygously comprises QTL9 and Tm-2 2 The gene or its variant, and homozygously or heterozygously comprising the QTL11 of the present invention, this combination provides resistance to ToBRFV, ToMV and TMV. If appropriate, further resistances may also be added.
[0104] As disclosed in application PCT / IB2019 / 00674 under the name of the same applicant, the presence of the Tm-1 gene can also improve resistance to ToBRFV. Therefore, the plant, cell or seed of the present invention also advantageously comprises the Tm-1 gene. The Tm-1 gene is defined in particular in Ishibashi et al., a publication in 2007 (An inhibitor of viral RNA replication is encoded by a plant resistance gene). PNAS August 21, 2007 104 (34) 13833-13838); the preferred 'Tm-1 gene' reported in the literature refers to a gene sequence encoding a protein with Tm-1 activity, i.e., the ability to inhibit viral replication of wild-type ToMV strains susceptible to Tm-1, such as the ToMV-L strain disclosed in the document. According to a preferred embodiment, the Tm-1 gene according to the present invention is a gene encoding a protein having a 754 amino acid sequence reported in Ishibashi et al., corresponding to SEQ ID No: 115 (NCBI BAF75724) or a gene encoding a protein having at least 75%, preferably at least 80% sequence identity with the sequence and exhibiting Tm-1 activity (reported in Ishibashi et al., 2007), i.e., the ability of wild-type Tm-1 susceptible ToMV strains to inhibit viral RNA replication.
[0105] Therefore, in addition to the QTL9 of the present invention, the present invention also includes tomato plants, cells or seeds homozygously or heterozygously comprising the Tm-1 gene, and potentially Tm-2 2 Gene and QTL11, or QTL3 on chromosome 11 as defined in WO2018 / 219941. Therefore, in addition to the QTL11 of the present invention, the present invention also includes a tomato plant, cell or seed that homozygously or heterozygously, preferably homozygously comprises the Tm-1 gene.
[0106] Still according to another embodiment, the plant of the present invention is used as a scion or rhizome in a grafting process. Grafting is a process that has been used for many years in crops such as Cucurbitaceae, but has only recently been used in tomatoes. Grafting can be used to provide a certain level of resistance to telluric pathogens on the ground, such as Phytophthora or certain nematodes. Therefore, grafting tends to prevent the plant or variety to be cultivated from contacting infected soil. The variety that is interested in being used as a graft or scion can be selected as an F1 hybrid, grafted on a resistant plant used as a rhizome. The resistant rhizome remains healthy and provides a normal supply from the soil for the graft separated from the disease.
[0107] As described above, the present invention relates to tomato plants showing improved ToBRFV resistance, as well as seeds producing these plants, and cells of these plants or seeds, or other plant parts, comprising resistance QTL9 and / or QTL11 in their genome introgressed from the tomato gene, and to the progeny of the plants of the present invention comprising said QTL.
[0108] Progeny include the first, second and all further offspring of a cross with a plant according to the invention, wherein the cross includes a cross with itself or a cross with another plant. The plant or seed according to the invention may be a progeny or descendant of a plant grown from the deposited seed LVSTBRFVRES2, deposited in NCIMB, deposit number NCIMB 43591. Plants grown from the deposited seeds are indeed homozygous for the QTL9 and QTL11 of the invention that confer an improved phenotype; therefore, they carry the QTL of interest on each homolog of chromosomes 9 and 11 in their genomes. They can be used to transfer these sequences to another background by crossing and selfing and / or backcrossing.
[0109] The present invention also relates to deposited seeds of LVSTBRFVRES2 (NCIMB 43591) and plants grown from one of these seeds, homozygously containing QTL9 conferring the desired phenotype, and QTL11. It is noteworthy that these seeds do not correspond to plant varieties, and they are not homozygous for most genes except the QTL of the present invention; therefore, their phenotypes are not fixed during breeding, except for the ToBRFV resistance / tolerance of the present invention; most of their phenotypic traits are separated during breeding, except for the ToBRFV resistance of the present invention.
[0110] The invention also relates to a plant or seed as defined above, i.e. containing the QTL9 and / or QTL11 of interest in a homozygous or heterozygous state, said sequences conferring an improved phenotype, possibly in combination, which plant or seed is obtainable by transferring the QTL from a tomato plant, representative seeds of which are deposited under NCIMB accession number NCIMB-43591, into another tomato genetic background, for example by crossing said plant with a second tomato plant parent and selecting plants with the QTL9 and / or QTL11 controlling the phenotype of interest. In such a cross, QTL9 and, if applicable, QTL11 can be transferred.
[0111] It should be noted that the seeds or plants of the present invention may be obtained by different treatments and are not exclusively obtained by essentially biological treatments.
[0112] According to this aspect, the present invention relates to a tomato plant or seed, preferably a non-naturally occurring tomato plant or seed, which may contain one or more mutations in its genome, which provide the plant with fruit and / or foliage resistance to Tomato Brown Crinkle Fruit Virus, the mutation being present, for example, in the genome of the plant, a representative sample of which is deposited at NCIMB under the deposit number NCIMB 43591.
[0113] In another embodiment, the present invention relates to a method for obtaining a tomato plant or seed carrying one or more mutations in its genome, which provides the plant with fruit and / or foliage resistance to Tomato Brown Crinkle Fruit Virus. This method is shown in Example 7 and may include:
[0114] a) treating M0 seeds of the tomato plant to be modified with a mutagen to obtain M1 seeds;
[0115] b) growing plants from the M1 seeds thus obtained to obtain M1 plants;
[0116] c) producing M2 seeds by self-pollination of M1 plants; and
[0117] d) Optionally repeat steps b) and c) n times to obtain M1+n seeds.
[0118] M1+n seeds are grown into plants and infected with ToBRFV. Surviving plants, or those with milder symptoms of ToBRFV infection, are propagated for one or more generations while continuing to select for fruit and / or foliage resistance to ToBRFV.
[0119] In this method, the M1 seeds of step a) can be obtained by chemical mutagenesis (e.g., EMS mutagenesis). Other chemical mutagens include, but are not limited to, diethyl sulfate (des), ethyleneimine (ei), propane sultone, N-methyl-N-nitrosocarbamate (mnu), N-nitroso-N-methylurea (NMU), N-ethyl-N-nitrosourea (enu), and sodium azide.
[0120] Alternatively, mutations are induced by radiation, for example selected from X-rays, fast neutrons, ultraviolet radiation.
[0121] In another embodiment of the present invention, the mutation is induced by genetic engineering. Such mutations also include the integration of sequences that confer resistance to ToBRFV fruit and / or foliage, and the replacement of resident sequences with alternative sequences that confer resistance or tolerance to ToBRFV fruit and / or foliage. Preferably, the mutation is the integration of QTL9 and / or QTL11 as described above to replace the homologous sequences of tomato plants. More preferably, the mutation is the replacement of sequences or fragments thereof contained in SNP TO-0201220 (SEQ ID NO: 1) and SNP TO-0201233 (SEQ ID NO: 14) on chromosome 9 of the tomato genome with homologous sequences present on chromosome 9 in the plant genome, and a representative sample of the plant is deposited in NCIMB under the accession number NCIMB43591, wherein the sequence or fragment thereof confers resistance to ToBRFV. According to another embodiment, the mutation is to replace the sequence or fragment thereof contained in SNP TO-0201237 (SEQ ID NO: 102) and SL2.50ch11_9924232 (SEQ ID NO: 115) on chromosome 11 of the tomato genome (for example, the sequence contained in SNP TO-0201237 and SNP TO-0201241) with a homologous sequence on chromosome 11 present in the plant genome, wherein a representative sample is deposited in NCIMB with the deposit number NCIMB43591, wherein the sequence or fragment thereof confers resistance to ToBRFV when present homozygously.
[0122] Genetic engineering techniques that can be used include the use of all the so-called New Breeding Techniques, which are various new technologies developed and / or used to create new characteristics in plants through genetic variation, with the aim of targeted mutagenesis, targeted introduction of new genes or gene silencing (RdDM). Examples of such New Breeding Techniques are the promotion of targeted sequence changes by using the following techniques: Zinc Finger Nuclease (ZFN) technology (ZFN-1, ZFN-2 and ZFN-3, see U.S. Pat.

A major part of targeted genome editing, another name for new breeding techniques, is the application of inducing DNA double-strand breaks (DSBs) at selected locations in the genome where the modification is desired. Such applications can be used to generate mutations (e.g., targeted mutations or precise natural gene editing) as well as precise insertion of genes (e.g., homologous genes, within endogenous genes, or heterologous genes). Applications that result in mutations are generally identified as site-directed nuclease (SDN) technologies, such as SDN1, SDN2, and SDN3. For SDN1, the result is a targeted, non-specific gene deletion mutation: the location of the DNA DSB is precisely selected, but the DNA repair of the host cell is random and results in small nucleotide deletions, additions, or substitutions. For SDN2, SDN is used to generate targeted DSBs and a DNA repair template (a short DNA sequence identical to the target DSB DNA sequence, except for one or a few nucleotide changes) is used to repair the DSB: this results in targeted and predetermined point mutations in the desired target gene. For SDN3, SDN is used with a DNA repair template containing a new DNA sequence (e.g., a gene). The result of this technology is the integration of this DNA sequence into the plant genome.The most likely application for the use of SDN3 is the insertion of cisgenic, intragenic or transgenic expression cassettes at selected genomic locations. A full description of each technique can be found in the 2011 report by the European Commission's Joint Research Centre (JRC) Institute for Foresight Technologies titled "New Plant Breeding Technologies - Current State of the Art and Prospects for Commercial Development".
[0123] According to the present invention, resistance or intermediate resistance to ToBRFV corresponds to a significant reduction in non-marketable fruits of the resistant plants of the present invention; in particular, the resistant plants disclosed herein produce tomatoes such that at least 70% of the fruits are marketable when ripe, i.e., without discolored spots, without browning calyx, without undersize and rough surface, without brown necrotic spots. Preferably, even in the case of double infection, at least 80% of the fruits are still marketable when ripe, preferably at least 90% of the fruits are still marketable when ripe.
[0124] As defined above, the plant of the present invention is characterized in that on chromosome 9, an introgression sequence is present in the chromosomal region defined by SNP TO-0201220 and the SNP with SEQ ID NO: 101, and / or on chromosome 11, an introgression sequence is present in the chromosomal region defined by SNP TO-0201237 and SL2.50ch11_9924232, preferably by SNP TO-0201237 and SNP TO-0201241. However, introgression sequences from currant tomato may be found outside these borders or flanking sequences.

According to a preferred embodiment, the present invention relates to a seed as described above that develops into a plant according to the first aspect of the present invention, thereby being resistant to ToBRFV infection due to the presence of resistance QTL9 or QTL11 or gene introgression sequences, as defined above.

[0133] The present invention also relates to cells of a tomato plant, such that these cells comprise in their genome a QTL9 or QTL11 of the present invention, independently conferring a desired phenotype to the tomato plant, as well as potential QTL9 and QTL11. QTL9 and QTL11 are the ones already defined within the framework of the present invention, characterized by: the same features and preferred embodiments already disclosed for plants and seeds according to the preceding aspects of the present invention. The presence of such a QTL, i.e. QTL9 or QTL11, can be revealed by the above disclosed techniques and is well known to a person skilled in the art. Among other things, it can be determined whether the QTL is homozygously or heterozygously present in the genome of this cell of the present invention. The advantageous feature of QTL9 is the presence of at least one resistance allele of the SNPs in Table H; preferably the presence of allele G of SNP TO-0201220, allele G of TO-0201221, allele A of TO-0201222, allele A of TO-0201223, allele A of TO-0201224, allele A of TO-0201225, allele A of TO-0201226, allele C of TO-0201227, allele C of TO-0201228, allele A of TO-0201229, allele C of TO-0201230, allele C of TO-0201231, allele G of TO-0201232 and / or allele G of TO-020133, and more preferably the presence of SNP Allele G of TO-0201220, allele G of SEQ ID TO-0201221, allele A of TO-0201229, allele C of TO-0201231 or allele G of TO-0201233, even more preferably allele G of SNP TO-0201220 and / or allele A of TO-0201229 are present.

[0134] The cell according to the invention may be any type of tomato cell carrying the QTL9 and / or QTL11 of interest, in particular an isolated cell and / or a cell capable of regenerating a whole tomato plant.
[0135] The present invention also relates to a tissue culture of non-regenerable or regenerable cells of the plant defined above according to the present invention; preferably, the regenerable cells are derived from the embryo, protoplast, meristem cell, callus, pollen, leaf, anther, stem, petiole, root, root tip, fruit, seed, flower, cotyledon and / or hypocotyl of the present invention, and the cells contain in their genome QTL9 and / or QTL11 independently conferring an improved phenotype, i.e., QTL9's fruit resistance to ToBRFV and QTL11's branch and leaf resistance to ToBRFV.
[0136] Preferably, the cell comprises QTL9 homozygously or heterozygously and also comprises QTL11 as defined in the context of the present invention.
[0137] The cell advantageously also comprises any additional resistance or tolerance genes as disclosed in the context of the first aspect of the invention, which also apply here.
[0138] The tissue culture is preferably capable of regenerating plants having the physiological and morphological characteristics of the aforementioned tomato plants, as well as regenerating plants having substantially the same genotype as the aforementioned tomato plants. The present invention also provides tomato plants regenerated from the tissue culture of the present invention.
[0139] The present invention also provides a plant as defined above or a protoplast from a tissue culture as defined above, said protoplast comprising QTL9 and / or QTL11 conferring the improved phenotype of the present invention.
[0140] The present invention also relates to tissues of the plants of the present invention; the tissues may be undifferentiated tissues or differentiated tissues. Such tissues contain one or more cells containing the QTL of the present invention.
[0141] The invention also relates to propagation material capable of producing resistant tomato plants according to the invention, comprising the introgression sequence or QTL as defined above.
[0142] According to another aspect, the present invention also relates to a tomato plant according to the present invention, preferably homozygously comprising the QTL9 according to the present invention, for use as a breeding partner in a breeding scheme for obtaining a plant having an improved phenotype according to the present invention. In fact, such a breeding partner homozygously comprises in its genome the QTL9 conferring the target phenotype. By crossing this plant with a tomato plant, in particular a line, the QTL9 according to the present invention conferring the desired phenotype can therefore be transferred to the offspring. Therefore, the plant according to the present invention can be used as a breeding partner for introgressing the QTL9 gene conferring the desired phenotype into a tomato plant or germplasm, i.e. ToBRFV resistance. Although plants or seeds heterozygously carrying the target QTL9 can also be used as breeding partners as described above, the separation of the phenotype may make the breeding program more complicated.
[0143] The improved phenotype of the present invention is resistance to ToBRFV, particularly fruit resistance or foliage resistance, or fruit and foliage resistance.
[0144] The breeding partner may further comprise QTL11 as defined in the present invention, preferably homozygously comprise QTL11 as defined in the present invention.
[0145] The introgressed QTL9 will be advantageously introduced into varieties containing other desired genetic traits, such as disease resistance, early fruit maturity, drought tolerance, fruit shape, etc. Preferably, the introgressed QTL9 will be advantageously introduced into varieties containing Tm-2 2 Gene in plants or varieties.
[0146] According to another embodiment, the present invention also relates to the same use of a tomato plant according to the present invention, but homozygously comprising the QTL11 according to the present invention as breeding partner.
[0147] The invention also relates to the same uses as plants or seeds deposited at NCIMB under the deposit number NCIMB 43591 containing homozygously QTL9 and / or QTL11, and plants derived therefrom. Said plants are also suitable as introgression partners for breeding programmes aiming at conferring a desired phenotype to tomato plants or germplasm.
[0148] In such a breeding program, selection of progeny displaying a desired phenotype or carrying a QTL9 linked to a desired phenotype can advantageously be based on the alleles of the SNP markers, particularly based on the alleles of the SNP markers of the invention having SEQ ID NOs: 1-101.
[0149] For QTL9, preferably, the progeny of the plant are selected in the presence of SNPs G allele of TO-0201220, G allele of TO-0201221, A allele of TO-0201222, A allele of TO-0201223, A allele of TO-0201224, A allele of TO-0201225, A allele of TO-0201226, C allele of TO-0201227, C allele of TO-0201228, A allele of TO-0201229, C allele of TO-0201230, C allele of TO-0201231, G allele of TO-0201232 and / or G allele of TO-020133, more preferably in the presence of SNPs The progeny of the plant are selected in the presence of allele G of TO-0201220, allele G of SEQ ID TO-0201221, allele A of TO-0201229, allele C of TO-0201231 or allele G of TO-0201233, and even more preferably in the presence of allele G of SNP TO-0201220 and / or allele A of TO-0201229.
[0150] Alternatively, selection may be made based on the presence of any one resistance allele of the 101 SNPs of the present invention, or a combination of these alleles, that are associated with an improved phenotype.
[0151] This selection will be based on the presence of the target allele in the sample of genetic material of the plant to be selected. The presence of this or these alleles indeed confirms the presence of the QTL9 of the present invention or the gene introgression sequence at the locus defined by the SNP. However, after a point mutation or recombination event, it is conceivable that at least one or two of these alleles are lost, and the remaining chromosome fragment carrying the target QTL9 still confers the target phenotype.
[0152] Selection of progeny carrying QTL11 can advantageously be performed based on the alleles of markers having SEQ ID NOs: 102-115, preferably based on the alleles of SNP markers having SEQ ID NOs: 102-111, preferably based on allele G of TO-0201237, allele A of TO-0201238, allele A of TO-0201239, allele A of TO-0201240, allele A of TO-0201241, allele CT of SL2.50ch11_9684449, allele A of SL2.50ch11_9779896, allele B of SL2.50ch11_9779897, allele C of SL2.50ch11_9779898 The presence of gene AT, allele C of SL2.50ch11_9823405 and allele GT of SL2.50ch11_9924232; for example, by the presence of at least one of allele G of TO-0201237, allele A of TO-0201238, allele A of TO-0201239, allele A of TO-0201240 and allele A of TO-0201241.
[0153] Therefore, plants according to the invention or plants grown from seeds deposited under accession number NCIMB 43591 are particularly valuable in marker-assisted selection for obtaining commercial tomato lines and varieties having the improved phenotype of the invention.
[0154] The invention also relates to the use of said plants in procedures aimed at identifying, sequencing and / or cloning gene sequences conferring a desired phenotype.
[0155] Any of the specific embodiments described for the previous aspects of the invention also apply to this aspect of the invention, particularly with respect to the characteristics of QTL9 and QTL11 that confer the phenotype of interest.
[0156] According to yet another aspect, the present invention also relates to a method or process for the production or breeding of tomato plants, particularly commercial plants and inbred lines, having a desired phenotype. The present invention indeed also relates to the transfer of the QTL or gene introgression sequence of the present invention conferring ToBRFV resistance to other tomato plants, particularly other tomato varieties, or other species or inbred lines, and can be used to produce new types and varieties of tomatoes.
[0157] In this regard, the present invention also includes a method for breeding a tomato plant having resistance to ToBRFV, comprising the steps of crossing a plant grown from the deposited seed LVSTBRFVRES2 NCIMB 43591 carrying the QTL9 of the present invention conferring resistance to ToBRFV or its progeny with an initial tomato plant preferably lacking said QTL. The QTL is as defined above, i.e., introgressed from the tomato gene of currant, preferably present in the genome of the seed of LVSTBRFVRES2, NCIMB deposit number 43591. The QTL can be identified by at least one resistance allele of a SNP marker having SEQ ID NO: 1-101.
[0158] The present invention also relates to a method for conferring ToBRFV resistance to a tomato plant, comprising genetically modifying the plant to introduce the QTL9 resistance of the present invention. The QTL9 is as defined above and is preferably present in the genome of seeds of LVSTBRFVRES2, NCIMB deposit number 43591. The genetic modification can be performed by any method or means well known to those skilled in the art.
[0159] The present invention also relates to the same method for breeding tomato plants with ToBRFV resistance associated with QTL11 but not QTL9 and conferring tomato plants ToBRFV resistance associated with QTL11 but not QTL9. In this case, the QTL can be identified by at least one resistance allele of a marker having SEQ ID NOs: 102-115.
[0160] Therefore, the present invention relates to a breeding method for tomato plants with ToBRFV resistance, comprising the following steps: crossing a plant grown from the deposited seed NCIMB 43591 or its progeny carrying QTL9 on chromosome 9, which is introgressed from the currant tomato gene and confers ToBRFV resistance, with an initial tomato plant lacking the QTL9, wherein the QTL9 on chromosome 9 is present in the genome of the plant seed LVSTBRFVRES2, NCIMB deposit number 43591, and can be identified by allele G of SNPTO-0201220, allele G of SEQ ID TO-0201221, allele A of TO-0201229, allele C of TO-0201231 or allele G of TO-0201233.
[0161] The present invention also relates to a method for breeding tomato plants resistant to ToBRFV, comprising the steps of: breeding seeds from the deposited NCIMB Plants grown from 43591 or its progeny are crossed with an initial tomato plant lacking the QTL11, wherein the QTL11 on chromosome 11 is present in the genome of plant seeds LVSTBRFVRES2, NCIMB deposit number 43591, and can be identified by allele G of TO-0201237, allele A of TO-0201238, allele A of TO-0201239, allele A of TO-0201240, allele A of TO-020124, allele CT of SL2.50ch11_9684449, allele AT of SL2.50ch11_9779896, allele C of SL2.50ch11_9823405 or allele GT of SL2.50ch11_9924232.
[0162] In particular, the present invention also relates to a method or process for producing plants resistant to ToBRFV, comprising the following steps:
[0163] a) crossing a plant grown from the deposited seed NCIMB 43591 or a progeny thereof comprising QTL9 conferring ToBRFV resistance, with a starting tomato plant preferably lacking said QTL,
[0164] b) selecting a plant comprising the QTL9 of the present invention among the progeny thus obtained;
[0165] c) Optionally, the plants obtained in step b) are self-pollinated one or more times, and the plants thus obtained that are resistant to ToBRFV, whether fruit resistance, foliage resistance or both, are selected in the progeny.
[0166] Optionally, the method or process may include the following steps instead of step a):
[0167] a1) crossing a plant grown from the deposited seed (NCIMB 43591) or a progeny thereof corresponding to the deposited seed comprising QTL9 conferring ToBRFV resistance, and an initial tomato plant preferably lacking said QTL,
[0168] a2) Increase F1 hybrids by selfing to create F2 populations.
[0169] In the above methods or processes, preferably SNP markers are used in step b) and / or c) for selecting plants carrying a sequence conferring the desired resistance phenotype.
[0170] The SNP marker is preferably one or more of the 101 SNP markers of the present invention having SEQ ID NOs: 1 to 101, including all combinations thereof mentioned elsewhere in this application, and preferably has SNPs having SEQ ID NOs: 1-14.
[0171] By selecting plants based on the alleles of one or more SNPs, it can be understood that when the allele of the SNP is an allele of the LVSTBRFVRES2 parent corresponding to the SNP but not the allele of the initial tomato plant, the plant is selected as having ToBRFV resistance relative to the initial plant, whether it is fruit tolerance / resistance, foliage tolerance / resistance or both. For example, when allele G of SNP TO-0201220, allele G of TO-0201221, allele A of TO-0201222, allele A of TO-0201223, allele A of TO-0201224, allele A of TO-0201225, allele A of TO-0201226, allele C of TO-0201227, allele C of TO-0201228, allele A of TO-0201229, allele C of TO-0201230, allele C of TO-0201231, allele G of TO-0201232 and / or allele G of TO-020133 are detected, more preferably, when allele G of SNP TO-0201220, SEQ ID NO: 1, allele C of SNP TO-0201231, allele C of SNP TO-0201232 and / or allele G of SNP TO-0201233 are detected. When allele G of TO-0201221, allele A of TO-0201229, allele C of TO-0201231, allele G of TO-0201232 or allele G of TO-0201233, and even more preferably when allele G of SNP TO-0201220 and / or allele A of TO-0201229 are detected, plants having the improved phenotype of the present invention can be selected.
[0172] Preferably, the tomato plant of step a) is an elite line for obtaining plants with commercially desirable traits or desirable horticultural traits. Advantageously, due to the Tm-2 2 When the gene is present homozygously or heterozygously, the plant is resistant to TMV.
[0173] The method or process as defined above may advantageously comprise a backcrossing step, preferably after step c), to obtain plants having all the characteristic features of a tomato plant. Thus, the method or process for producing a plant having these characteristics may also comprise the following additional steps:
[0174] d) backcrossing the resistant plants selected in step b) or c) with tomato plants;
[0175] e) selecting plants carrying the QTL9 or introgression sequence of the present invention.
[0176] The plant used in step a), i.e. the plant corresponding to the deposited seeds, may be a plant grown from the deposited seeds; it may also be any plant carrying QTL9 or gene introgression sequences, conferring a phenotype, preferably homozygously carrying these sequences according to the first aspect of the invention.
[0177] Preferably such a plant further comprises the defined QTL11, preferably comprises the defined QTL11 homozygously.
[0178] In step e), the SNP marker can be used to select plants that are resistant to ToBRFV relative to the initial plant. The SNP marker is a marker of the present invention, as described in the previous sections. According to a preferred embodiment, the method or process of the present invention is carried out so that, for at least one selection step, i.e. b), c) and / or e), the selection is based on the detection of at least one resistance allele of a SNP having SEQ ID NO: 1-101. Preferred alleles and combinations have been disclosed and are suitable for this embodiment of the present invention.
[0179] It should be noted that when selecting plants with an improved phenotype and homozygously carrying the QTL conferring this phenotype, the selection is based on one or more SNPs of the present invention, in the presence of the allele representing the QTL, i.e. the allele LVSTBRFVRES2 parent, in combination with the absence of the allele representing the relapse-susceptible tomato parent.
[0180] Selection can also be based on any other markers that are related to the introgressed sequences and represent the presence of these introgressed sequences by contrast to the resident sequences of the susceptible parent. Methods for defining surrogate markers are also within the scope of the invention and are disclosed in another section.
[0181] The plants selected in step e) are preferably commercial plants, in particular plants having a fruit weight of at least 10 g but preferably 25 g, at least 100 g, at least 150 g or at least 200 g when fully mature under normal culture conditions.
[0182] Preferably, steps d) and e) are repeated at least twice, preferably three times, not necessarily with the same tomato plants. The tomato plants are preferably breeding lines.
[0183] In the selection step of each of the processes disclosed above, one may additionally select for resistance to a nematode trait or resistance to ToMV.
[0184] The selfing and backcrossing steps may be performed in any order and may be inserted, for example, backcrossing may be performed before and after one or more selfings, and selfing may be performed before and after one or more backcrossings.

Thus, identification of plants homozygous for the QTL or introgression sequence of the present invention will be based on identification of a resistance allele of at least one SNP having SEQ ID NO: 1-101 for QTL9, as well as the absence of a susceptible allele of said SNP. For example, identification of plants homozygously carrying the QTL9 of the present invention will be based on the identification of SNPs allele G of TO-0201220, allele G of TO-0201221, allele A of TO-0201222, allele A of TO-0201223, allele A of TO-0201224, allele A of TO-0201225, allele A of TO-0201226, allele C of TO-0201227, allele C of TO-0201228, allele A of TO-0201229, allele C of TO-0201230, allele C of TO-0201231, allele G of TO-0201232 and / or allele G of TO-020133, and the absence of the corresponding susceptible alleles, i.e., SNPs.

Therefore, the present invention also relates to a method for improving the yield of tomato plants in an environment infected by ToBRFV, comprising growing a tomato plant whose genome comprises QTL9 on chromosome 9 and / or QTL11 on chromosome 11, as defined according to the preceding aspects of the present invention, and conferring resistance to ToBRFV to the plant.
[0251] Preferably, the method comprises a first step of selecting or screening a tomato plant comprising said QTL or introgression sequence of interest. The method may also be defined as a method for increasing productivity of a tomato field, tunnel or greenhouse, or as a method for reducing the intensity or number of chemical or fungicide applications in tomato production.
[0252] The present invention also relates to a method for reducing tomato production losses under conditions of ToBRFV infection or infection, comprising growing a tomato plant as defined above.
[0253] These methods are particularly valuable for populations of tomato plants in the field, tunnel, or greenhouse.
[0254] Alternatively, the method for improving yield or reducing tomato production losses may include: a first step, namely identifying a tomato plant that is resistant / tolerant to ToBRFV and contains in its genome the QTL9 and / or QTL11 of the present invention that confers ToBRFV resistance to the plant; and then growing the resistant plant in an environment infected or likely to be infected by the virus. According to a preferred embodiment, the plant to be identified in the first step contains allele A of TO-0201229, or at least one resistance allele of a SNP having SEQ ID NOs: 1 to 101.
[0255] The resistant plants of the present invention are also able to limit the growth of ToBRFV, thereby limiting the infection of other plants and the spread of the virus. Therefore, the present invention also relates to a method for protecting a field, a tunnel or a greenhouse or any other type of plantation from infection with ToBRFV, or at least limiting the level of infection of the field, tunnel or greenhouse with ToBRFV, or limiting the spread of ToBRFV in a field, tunnel or greenhouse, in particular in a tomato field. This method preferably includes the step of growing a resistant or tolerant plant of the present invention, i.e. a plant comprising in its genome QTL9 on chromosome 9 that confers ToBRFV resistance to the plant. The plant of the present invention to be used preferably comprises allele A of TO-0201229, or at least one resistance allele of a SNP having SEQ ID NO: 1 to 101. According to another embodiment, the plant to be used comprises at least one resistance allele of a marker having SEQ ID NO: 102 to 115.
[0256] The invention also relates to the use of ToBRFV-resistant plants for controlling ToBRFV infection or infestation in fields, tunnels or greenhouses or other plantations; such plants are plants of the invention, comprising in their genome QTL9 and / or QTL11, or sequences of gene introgression from tomato on chromosomes 9 or 11 as defined above. This use or method is also a method for disinfecting a field, tunnel or greenhouse by reducing the virus population.
[0257] All preferred characteristics of the QTL are as defined in conjunction with the other aspects of the invention, i.e., preferably present in seeds of LVSTBRFVRES2 (NCIMB deposit number 43591), and identifiable by SNP markers having SEQ ID NOs: 1 to 101 for QTL9; preferably identifiable by SNP markers having SEQ ID NOs: 1 to 14, preferably identifiable by SNP markers having SEQ ID NOs: 1 to 14. Allele G of TO-0201220, allele G of TO-0201221, allele A of TO-0201222, allele A of TO-0201223, allele A of TO-0201224, allele A of TO-0201225, allele A of TO-0201226, allele C of TO-0201227, allele C of TO-0201228, allele A of TO-0201229, allele C of TO-0201230, allele C of TO-0201231, allele G of TO-0202132, and / or allele G of TO-020133 can be identified by a sequence having SEQ ID NO: 1 for QTL11. It is identified by using markers NO:102 to 115, preferably allele G of TO-0201237, allele A of TO-0201238, allele A of TO-0201239, allele A of TO-0201240, allele A of TO-0201241, allele CT of SL2.50ch11_9684449, allele AT of SL2.50ch11_9779896, allele C of SL2.50ch11_9823405 and / or allele GT of SL2.50ch11_9924232 of QTL11.
[0258] In a further aspect, the present invention also relates to a method for producing tomatoes, comprising:
[0259] a) growing a tomato plant of the invention comprising QTL9 and / or QTL11 as defined above;
[0260] b) allowing the plant to bear fruit; and
[0261] c) harvesting the fruits of the plant, preferably when ripe and / or before ripening.
[0262] All preferred embodiments concerning QTL9 and QTL11 have been disclosed in the context of the previous aspects of the invention.The method may advantageously comprise the further step of processing said tomatoes into a processed tomato food.

[0271] Example
[0272] Example 1 :Materials and methods.
[0273] 1.A. Source Verification Testing .
[0274] The test was performed in triplicate with approximately 15 plants per germplasm or genetic background tested. Plants were sown and infected at the 2-leaf stage. Scoring was then performed by visual assessment of leaves at 7, 14 and 28 days post infection.
[0275] For this test, the criteria are as follows:
[0276] 9: No symptoms
[0277] 5: Moderate mosaic and / or necrosis symptoms
[0278] 1: Severe mosaic and / or necrosis symptoms
[0279] At 32 days dpi, the four accessions were tested plant by plant by Elisa and the two susceptible controls were batch tested.
[0280] 1.B. Phenotyping of F2 population
[0281] Plants were sown and infected at the 2-leaf stage and then scored by visual assessment of leaves at 7, 14 and 28 days post infection.
[0282] For this test, the criteria are as follows:
[0283] 9: No symptoms
[0284] 7: Mild mosaic symptoms
[0285] 5: Moderate mosaic symptoms
[0286] 3: Strong mosaic symptoms and / or bubbling
[0287] 1: Very strong mosaic symptoms and / or bubbling and / or deformation
[0288] For QTL analysis, the inventors used different phenotypic variables / traits, specifically annotation at 14 dpi, annotation at 21 dpi, annotation at 28 dpi, AUDPC.
[0289] AUDPC (area under the disease progression curve) was calculated using the following formula:
[0290]
[0291] Wherein, "n" is the number of symptom assessments, "y" is the symptom intensity (1 to 9), and "t" is the time in dpi (days post inoculation).
[0292] 1.3.DNA extraction:
[0293] According to the manufacturer's procedure, use DNA was extracted from ground leaves using the Plant Kit (Macherey-Nagel). DNA purification was based on the Magnetic-bead10 technology for the isolation of genomic DNA from plant tissues. DNA concentration was determined using the Quant-iT TM Quantification by dsDNA Assay Kit.
[0294] 1.4. Protocol for evaluating ToBRFV resistance under field conditions
[0295] Inoculation phase: 10 and 17 days after planting. The plants are thus infected twice. Each time the 2 youngest leaves are inoculated. Finally, 4 different leaves are inoculated.
[0296] Inoculum preparation:
[0297] Isolate: ToBRFV Jordan local strain 2017. ToBRFV-infected young leaves were taken from naturally infected plants and from plants resistant to TYLCV (Ty) and TMV to avoid the presence of multiple viruses in the inoculum.
[0298] 1 g of young leaves with ToBRFV symptoms was required to prepare 4 mL of inoculum by grinding.
[0299] Verification and inoculation of inoculum:
[0300] Before inoculation, the inoculum was checked for the presence of ToBRFV using TMV immunostrips (which are not specific and can also recognize ToBRFV) and for the absence of PepMV (Pepino) using PepMV immunostrips. TMV immunostrips can detect the presence of ToBRFV in the inoculum as long as the infected plants are TMV-resistant.
[0301] The inoculum to be applied is positive on the TMV immunoassay and negative on the PepMV immunoassay.
[0302] The inoculum was applied to two young leaves of the plant to be tested by gently rubbing this leaf with a rough sponge soaked in the inoculum.
[0303] Symptom assessment
[0304] The first evaluation was done when the first bunch of fruits was red and the second bunch of fruits turned red.
[0305] When at least the 3rd string is red, the 2nd evaluation is performed.
[0306] Standards for leaf symptoms:
[0307] 9: no symptoms, / 7: weak symptoms on a few leaves, / 5: moderate symptoms on some leaves, / 3: moderate symptoms on all leaves, / 1: strong symptoms on all leaves.
[0308] Fruit symptom criteria:
[0309] 9: All fruits showed no symptoms
[0310] 7: Mild symptoms (discoloration) on one or a few fruits
[0311] 5: Mild / moderate fruit discoloration on at least 2-3 fruits
[0312] 3: Moderate / intense fruit discoloration and / or small fruit deformation on more than 30% of the fruits.
[0313] 1: Very intense discoloration and / or moderate / intense fruit deformation and / or necrotic spots on more than 50% of the fruits.
[0314] 1.5. Stemphylium spp. resistance assessment protocol
[0315] Stomachium is a plant pathogenic fungus; it is the causative agent of gray leaf spot on tomato. The Sm gene from the currant tomato (Lycopersicum pimpinellifolium) provides genetically dominant resistance to Stomachium.
[0316] Inoculum preparation:
[0317] Stolonifera, Sicilian strain, stored at -80°C. The inoculum was prepared directly from cryopreserved tubes after incubation on petri dishes with V8 medium. Conidia were obtained by scraping the surface of the medium, suspended in water containing 1% glucose, and then filtered on muslin cloth. Conidia containing 10 4 Up to 10 5 A solution of conidia.
[0318] Vaccination:
[0319] The seedlings to be tested are at the 3 expanded leaves stage, corresponding to 17 to 24 days after sowing.The inoculum is applied by spraying on all leaf surfaces until droplets form.
[0320] Symptom Assessment:
[0321] The leaves were then scored by visual assessment 7 to 8 days after infection.
[0322] For this test, the criteria are as follows:
[0323] 9: No symptoms
[0324] 7: Some brown necrotic lesions, fewer in number than susceptible plants
[0325] 1: There are small or large brown necrotic lesions on both sides of the leaves.
[0326] Example 2 : Identification of ToBRFV resistance donor and preliminary positioning of QTL.
[0327] Identification of suitable wild donors of ToBRFV resistance
[0328] The inventors screened over 500 different wild germplasms to identify potential sources of resistance to ToBRFV, thereby potentially introgressing resistance-conferring sequences in these wild germplasms into a tomato background, particularly in commercial plants.
[0329] Although the type of resistance the inventors expected was fruit tolerance / resistance, this test could not be applied to wild germplasm with different fruit size and form. Therefore, the inventors decided to rank the sources in the leaf symptom test as a surrogate for fruit resistance since this parameter could not be screened.
[0330] Among the screened wild germplasm, only four potential sources (0.9%) were identified in the species S. habrochaites, S. chilense and S. ribes, suggesting that, in contrast to other viruses, it is difficult to find sources of resistance to ToBRFV.
[0331] All of these sources had a high percentage of symptom-free plants, however these plants were all positive by ELISA, indicating that no overall resistance or immunity was found.
[0332] For the control, two plants, S1 and S2, known to be susceptible to ToBRFV were used; however, due to the 2 In the presence of the gene, the control plant S2 was resistant to TMV.
[0333] Plants were evaluated for potential resistance / tolerance at the foliage level; in fact, due to the different fruit shapes, colors, and sizes of these wild accessions, it was not possible to rank resistance at the fruit level.
[0334] Table A reports the results obtained:
[0335] Table A : Evaluation of ToBRFV resistance in 4 potential sources and 2 controls by visual scoring and ELISA testing
[0336]
[0337] However, after 32 dpi, all plants tested positive by ELISA, indicating that the resistance carried by these plants was not complete (Table A).
[0338] In view of the results obtained, the inventors decided to focus further work on source D, which showed a better level of leaf resistance at 28 dpi, although the aim of this study was to identify fruit resistance sources rather than leaf resistance sources.
[0339] F2 Positioning - HMC1* Source D - Manual Testing
[0340] Four F2 populations were developed by crossing the resistant wild-source D with the susceptible parent HMC1, which is a breeding line with an indeterminate growth habit and red round fruits weighing about 100 g. It contains Tm-2 2 Gene.
[0341] Visual scoring was performed on different days: 7, 14 and 28 dpi (see Table B above).
[0342] Table B shows the results of the F2 screening under artificial conditions: plants were scored on a scale of 1 to 9, where plants scoring “1” or “3” would be considered susceptible, plants scoring “5” would be considered moderately resistant, and plants scoring “7” or “9” would be highly resistant in terms of foliar resistance.
[0343] The number of plants with scores of 1, 3, 5, 7, and 9 is reported in columns 4-8. Column 9 (1=S) indicates the number of plants with scores of 1, 3, 5, or 7. Column 10 (9=R) indicates the number of plants with a score of 9. Columns 11 and 12 report the percentage of plants with a score of "S" (scores of 1, 3, 5, or 7) and a score of "R" (score of 9).
[0344] Table B: Scores of source D and its progeny
[0345]
[0346] QTL analysis
[0347] DNA was extracted as detailed in Example 1. For QTL analysis, the inventors used different phenotypic variables / traits: Annotated 14 dpi, Annotated 21 dpi, Annotated 28 dpi, AUDPC.
[0348] AUDPC (area under the disease progression curve) was calculated using the following formula:
[0349]
[0350] Wherein, "n" is the number of symptom assessments, "y" is the symptom intensity (1 to 9), and "t" is the time in dpi (days post inoculation).
[0351] Genotyping of the F2 population (based on source D and HMC1) was done using a panel of 169 SNPs. These SNPs were selected based on:
[0352] Polymorphism / allele frequency
[0353] SNP physical map distance is evenly distributed
[0354] QTL analysis was performed using the QTL detection (ANOVA) model for parental populations in MAST - A Marker Assisted Selection Tool (proprietary software).
[0355] Positioning results (see Figure 1 , illustrating the P-value plot for the trait corresponding to AUDPC) revealed two QTL candidates associated with ToBRFV resistance, which were located on chromosome 9 (QTL9) and chromosome 11 (QTL11), with the positive alleles coming from source D.
[0356] Table C summarizes the markers significantly associated with QTL9 and QTL11 associated with ToBRFV resistance and their locations in the tomato genome.
[0357] SNP chromosome Position SL2.5 P-value loci LOD R2. Locus TO-0196745 9 3 987 296 2.21E-05 4.66 0.04 TO-0145530 9 4 654 259 1.41E-07 6.85 0.05 TO-0178115 9 13 623 470 4.74E-06 5.32 0.04 TO-0145207 9 40 039 587 4.26E-06 5.37 0.04 TO-0008214 11 4 524 671 7.38E-08 7.13 0.05
[0358] The results showed that QTL9 responsible for ToBRFV resistance was located between position 3987296 and position 40039587 on chromosome 9 of the SL2.50 version of the tomato genome. This region of chromosome 9 is a region known to have a low recombination rate.
[0359] QTL11 responsible for ToBRFV resistance is located at position 4524671 on chromosome 11, also based on the SL2.50 version of the tomato genome.

[0361] BC1F2 QTL mapping and validation
[0362] A BC1F2 population between origin D and the susceptible parent HMC1 has been developed using the SNPs described in Table C. 158 individual plants have been phenotyped under field inoculation conditions in Jordan as described in Example 1.
[0363] Fruit symptoms were rated on a 9 to 1 scale:
[0364] 9: No symptoms - 7: Mild symptoms on a few fruits - 5: Moderate symptoms on some fruits - 3: Moderate symptoms on all fruits - 1: Strong symptoms.
[0365] Table D shows the results of the BC1F2 screening under field inoculation conditions: plants were scored on a scale of 1 to 9, where plants with a score of 1 or 3 would be considered susceptible, plants with a score of 5 would be considered moderately resistant, and plants with a score of 7 or 9 would be considered highly resistant. Fruit evaluation was not performed on source D due to fruit size, i.e. due to the small fruit of the currant tomato source.

[0368] DNA was extracted from leaves as described in Example 1.
[0369] The BC1F2 population was genotyped with a subset of SNPs significantly associated with ToBRFV resistance in the F2 mapping population. Marker trait associations were done by crossed ANOVA in MAST - Marker Assisted Selection Tool (proprietary software).
[0370] Mapping results showed that QTL9 was associated with fruit resistance to ToBRFV; the same region that had been associated with leaf resistance.
[0371] BC3F2 QTL Mapping - Field Testing
[0372] Three BC3F2 populations of approximately 140 individuals each between origin D and HMC1 were evaluated under inoculated field conditions. The inoculation protocol and symptom evaluation were the same as for BC1F2 and described in Example 1.
[0373] The scoring of these plants is detailed in Table E; the scale of scores 1 to 9 is the same as detailed for BC1F2.

[0376] DNA was extracted from leaves as described in Example 1.
[0377] BC3F2 individuals were genotyped with a subset of polymorphic SNPs on chromosomes 9 and 11 that were identified as associated with ToBRFV resistance in the F2 mapping population.
[0378] A genetic map of chromosomes 9 and 11 was constructed using JoinMap software to confirm the position and order of the markers.
[0379] QTL detection was performed using MapQTL software and genetic maps completed for these families.
[0380] The QTL mapping results confirmed the presence of a major QTL for fruit resistance to ToBRFV on chromosome 9. Peak-associated markers are described in Table F.

[0384] Example 4: Line resequencing and identification of unique SNPs.
[0385] Six tomato lines (including three ToBRFV tolerance / resistance sources, including source D and the line used in WO2018 / 219941 (HAZTBRFVRES1)) and three susceptible lines used as replicates in the mapping population were resequenced.
[0386] Seeds were sown, DNA was extracted from fresh leaves, and whole genome sequencing was performed.
[0387] The minimum sequencing depth was set to 20X. Sequencing was performed using Illumina NovaSeq 2x150nt technology.
[0388] Reads were mapped to the SL2.40 tomato reference genome and variant calling analysis was performed using samtools. In order to identify SNPs from source D as uniquely as possible, SNPs were filtered and alleles found in source D were compared with SNP alleles identified in other lines of the project and 360 tomato genomes ("Genomic analyses provide insights into the history of tomato breeding"; Lin et al. Nature Genetics, 2014).
[0389] On this basis, 310 unique SNPs from source D were identified in the interval containing QTL9 (from SL2.40ch09: 10 Mb to 55 Mb). To select the best SNPs, some quality filters were applied (unique Blast on the tomato genome and %AT in flanking sequences). A list of 101 SNPs was selected (see Table H).
[0390] 14 SNPs (see Table G) have been tested in a large number of backgrounds and they have confirmed their ability to track the presence of QTL 9. Five of them (see Table G) showed very good results in terms of specificity for origin D.

[0405]
[0406] Therefore, these SNPs allow to distinguish plants with QTL9 described in the present invention from plants derived from HAZTBRFVRES1 described in WO2018 / 219941, which have a different QTL providing tolerance to ToBRFV on chromosome 9. Therefore, the QTL disclosed in the present invention is significantly different in sequence from the QTL disclosed in WO2018 / 219941.
[0407] Example 5: Characterization of new QTL9 in field trials.
[0408] Two different trials were conducted in Jordan to confirm that in addition to the sequence differences between QTL9 of the present invention and the QTL mentioned in WO2018 / 219941, these different sequences also confer different types of ToBRFV resistance.
[0409] The first trial T1 (372 plants) was carried out in a tunnel in summer using different elite lines (checks), controls S1 and S2 mentioned in Examples 2-4, and plants containing the QTLs on chromosomes 9 and 11 mentioned in WO2018 / 219941.
[0410] A second trial, T2 (1165 plants), was conducted the following winter using two tunnels, including the same elite lines (check) and controls as in the previous trial, T1, and BC3F2 produced from source D, as described in Example 4.
[0411] In this example, the type / origin of the sequences found at the loci of QTL9 and QTL11 on chromosomes 6 and 9 of the test plants were defined as follows:
[0412] →Sequences found in elite lines at the QTL9 and QTL11 loci, as well as extended “alleles” of these loci in elite lines, are coded as “Re”;
[0413] →Sequences found in susceptible lines S1 and S2 at the QTL9 and QTL11 loci (“alleles” of these loci in susceptible lines) are coded as “S”;
[0414] → Sequences located at the QTL9 and QTL11 loci found in tolerant / resistant plants derived from HAZTBRFVRES1 described in WO2018 / 219941 (“alleles” of these loci in HAZTBRFVRES1) are coded as “Rh”;
[0415] → The sequences found in the resistant plant BC3F2 from origin D at the QTL9 and QTL11 loci (the "alleles" of these loci in the plants of the present invention) are coded as "Rd".
[0416] The plants were inoculated twice, first one week after planting and second two weeks later, as described in Example 1.
[0417] The plants were then scored for fruit and leaf symptoms according to the criteria mentioned in Example 1.4. Leaf symptoms were assessed at the adult stage (plants bearing red fruit), however, leaf symptoms were difficult to assess due to the sparse young leaves.
[0418] Statistical analysis of results.
[0419] The data were analyzed using a mixed model to determine the level of resistance conferred by the "allele" found at the QTL9 locus of the plants, taking into account other potential effects, namely the "allele" found at the QTL11 locus, the genotype of the plants, and the effects of tunneling. The mixed model was as follows:
[0420] Score = μ + (genotype) random + tunnel + QTL9 + QTL11 + ε
[0421] where score (fruit resistance or leaf resistance) is the observed variable, μ is the mean of the trait, ε is the residual, and (genotype) random, tunnel, QTL9 and QTL11 are the effects.
[0422] Since inspections are present in all tunnels, the tunneling effect is estimated.
[0423] The genotype effect was treated as a random effect to capture the variability of the population from which the tested varieties were drawn.
[0424] For each genotype and each trait (fruit symptoms and leaf symptoms) at the QTL9 locus, the inventors extracted adjusted values in order to better estimate the potential of each genotype independent of other effects.
[0425] For example, for the genotype corresponding to Rd / Rd, the adjusted value is:
[0426] μ+QTL9[RdRd]+average(genotype)+average(tunnel)+average(QTL11)
[0427] where μ is the estimated mean of the trait (fruit symptoms or leaf symptoms), QTL9[Rd / Rd] is the estimated effect of genotype RdRd on QTL9, and Mean(genotype), Mean(tunnel) and Mean(QTL11) are the means of the corresponding estimated effects.
[0428] Tukey's test was used for multiple comparisons between adjusted values
[0429] result:
[0430] Effects of QTL9 on fruit symptoms:
[0431] For traits corresponding to fruit symptoms, the mixed model detailed above was used to calculate adjusted values for the different tested genotypes regarding the QTL9 locus. The results are reported in Table I and are presented in Figure 2A and 2B Shown in.
[0432] Table I: Effects of QTL9 on fruit symptoms
[0433] QTL9_allele Fruit symptom adjustment Group N Rd 7,0853 A 203 R 5,73088 B 78 R 5,3609 BC 214 ReS 3,75473 CD 56 ReRe 3,46006 D 132 SS 2,51856 D 560
[0434] N = number of corresponding plants
[0435] Group: Group assigned according to Tukey test
[0436] For the sequence of the QTL9 locus, Rd, Rh, Re, and S correspond to the genotype of the plant.
[0437] From these results, it can be inferred that the presence of QTL9 defined in the present invention (corresponding to the Rd genotype in this example) provides a level of resistance that is significantly different from and significantly higher than the level of resistance provided by QTL2 defined in WO2018 / 219941 (corresponding to the Rh genotype in this example).
[0438] Furthermore, analysis of the effect of the alleles at QTL9 on fruit resistance showed that the Rd allele had a significant additive effect, as follows (extract from Table 1) and Figure 3 shown.
[0439] QTL9_allele Adjustment value Group N Rd 7,0853 A 203 R 5,3609 BC 214 SS 2,51856 D 560
[0440] Fruit score redistribution has also been determined by QTL9 genotypes. Figure 4 shown.
[0441] As shown in these results, QTL9 according to the present invention, in the homozygous state (genotype RdRd in this example), gave more than 80% of the plants a fruit score of 5, 7 or 9 (48, 61 and 59 out of 208, respectively). About 60% of the plants (120 out of 208) scored 7 or 9 after two rounds of infection, i.e., the fruit had almost no symptoms.
[0442] These results also demonstrate that QTL9 according to the invention, when present in a heterozygous state (genotype RdS in this example), gives about 50% of the plants a fruit score of 5, 7 or 9 (63, 36 and 13 out of 225, respectively). About 22% of the plants (49 out of 225) scored 7 or 9 after two rounds of infection, i.e. the fruit was almost symptom-free.
[0443] In contrast, for the RhRh genotype, also approximately 80% of the plants had fruit scores of 5, 7 or 9, but less than 35% of the plants had scores of 7 or 9 (30 and 1 of 89, respectively), ie, after two rounds of infection, the fruits were almost symptom-free.
[0444] Effects of QTL9 on leaf symptoms:
[0445] For traits corresponding to leaf symptoms, adjusted values for the different tested genotypes regarding the QTL9 locus were calculated using the mixed model detailed above. The results are reported in Table J and are presented in Figure 5 Shown in.
[0446] Table J: Effects of QTL9 on leaf symptoms

[0448] N = number of corresponding plants
[0449] Group: Group assigned according to Tukey test
[0450] For the sequence of the QTL9 locus, Rd, Rh, Re and S correspond to the genotype of the plant. From these results, it can be inferred that the presence of QTL9 defined in the present invention (corresponding to the Rd genotype in this example) provides a leaf resistance level that is significantly different from and significantly higher than the leaf resistance level provided by QTL2 defined in WO2018 / 219941 (corresponding to the Rh genotype in this example).
[0451] Furthermore, the results also showed that the heterozygous presence of QTL9 was sufficient to provide a high level of foliar resistance (the adjusted values for genotypes RdRd and RdS were statistically identical).
[0452] Example 6: Lineage resequencing and identification of unique SNPs on chromosome 11.
[0453] The same experiments disclosed in Example 4 for the QTL on chromosome 9 were applied to the QTL identified by the inventors on chromosome 11. The SNP analysis was performed on the same plant population.
[0454] The SNPs are informative about the presence of QTL11 according to the invention and are reported in Table K below (SEQ ID NOs: 102-111), as well as their location in the genome of the SL2.50 version and the susceptible and resistant alleles.
[0455] Then, the inventors conducted further searches to identify other markers for the presence of introgression sequences that confer resistance to ToBRFV. These markers are very specific to the introgression sequences from source D that confer resistance to ToBRFV.

[0460]
[0461] Example 7: Genetic modification of tomato seeds by ethyl methane sulfonate (EMS)
[0462] Seeds of tomato varieties were treated with EMS by dipping approximately 2000 seeds of each variety in an aerated solution of 0.5% (w / v) or 0.7% EMS for 24 hours at room temperature.
[0463] Approximately 1500 treated seeds per variety per dose of EMS are germinated and the resulting plants are preferably grown in a greenhouse, e.g., from May to September, to produce seed.
[0464] After maturity, the M2 seeds were harvested and batched in one pool per treatment. The resulting pool of M2 seeds was used as starting material to identify individual M2 seeds and plants resistant to Tomato Brown Ruffle Fruit Virus.
[0465] Example 8: Resistance to Stolonifera
[0466] WO2020 / 018783 discloses a genetic region on chromosome 11 of tomato containing a Stolonifera resistance allele from tomato plant Gooseberry, and allegedly also a TBRFV resistance allele, both of which are so closely linked that they are characterized as very similar markers and therefore introgressed at the same time. To confirm that the QTL on chromosome 11 identified by the inventors is different from the resistance allele disclosed in WO2020 / 018783, the inventors tested the plants according to the invention for Stolonifera resistance.
[0467] The protocol for Stolonifera resistance was as disclosed in Example 1.5.
[0468] result:
[0469] More than 157 different plants from 5 different genotypes were tested with at least 18 replicates per genotype.
[0470] The genotypes / cultivars tested were:
[0471] - A Sclerotium resistant control (R)
[0472] - A moderately resistant control of Sclerotium (IR)
[0473] - A Spatholobus susceptible control (S)
[0474] -Source D
[0475] -BC5F3 HMC1 * Source D
[0476] The results for Sclerotium resistance are reported in Table L below.
[0477]
[0478] Table L: Stolonifera resistance.
[0479] "Mean" means the average score of all plants from the same family according to the symptom evaluation detailed in 1.5. The meaning indicates whether the cultivar is considered resistant (R) or susceptible (S). QTL11 is a QTL according to the invention; its presence was tested with the markers disclosed in the previous examples. NT means not tested.
[0480] Conclusion: QTL11 from source D providing ToBRFV resistance according to the present invention is not associated with resistance to Stolonifera, contrary to the genetic resistance to ToBRFV according to WO2020 / 018783, since the tested plants, while containing the QTL11 of the present invention, were not resistant to Stolonifera.
[0481] Therefore, it can be concluded that QTL11 of the present invention is different from the resistance on chromosome 11 disclosed in WO2020 / 018783.
[0482] Example 9: Analysis of ToBRFV resistance provided by QTL11.
[0483] An F2 population between source D and susceptible parent HMC2 has been obtained. HMC2 is a line that is highly susceptible to ToBRFV at the leaf level. As described in Example 1.B, 134 individual plants were phenotyped for leaf symptoms after inoculation with ToBRFV and genotyped based on SNP markers of QTL11.
[0484] For traits corresponding to foliar symptoms, adjusted values for the different tested genotypes for the QTL11 locus were calculated using a mixed model similar to the one used for QTL9. The results are reported in Table M and are presented in Figure 6 Shown in.
[0485] Table M

[0487] Analysis of the effect of the alleles at QTL11 on foliage resistance showed a significant recessive effect of the resistance allele, as shown in Table M and Figure 6 shown.
