The present invention relates to an allele designated alpha-WOLF 24 which confers resistance to at least one Peronospora farinosa f. sp. spinacea race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that comprises in its amino acid sequence: a) the motif “MAEIGYSVC” (SEQ ID NO: 1) at its N-terminus; and b) the motif “KWMCLR” (SEQ ID NO: 2); and wherein the LRR domain of the protein has in order of increased preference at least 95%, 96%, 97%, 98%, 98.2%, 98.5%, 98.8%, 99%, 100% sequence similarity to SEQ ID NO: 10. The allele when present in a spinach plant confers complete resistance to at least Peronospora farinosa f. sp. spinacea race Pfs: 1, Pfs: 2, Pfs: 5, Pfs: 6, Pfs: 7, Pfs: 9, Pfs: 11, Pfs: 13, Pfs: 15 and Pfs: 17, and does not confer resistance to downy mildew race Pfs: 16.

The present invention relates to downy mildew, and especially downy mildew caused by the plant pathogen Peronospora farinosa, resistant spinach plants (Spinacia oleracea). The present spinach plants include a downy mildew resistance providing genomic fragment from Spinacia tetrandra. Specifically, the present invention relates to spinach plants being resistant to downy mildew, wherein the spinach plant includes a downy mildew resistance providing genomic fragment from Spinacia tetrandra such as spinach plants including in their genomes one or more nucleic acid sequences selected from the groups consisting of SEQ ID No. 1, SEQ ID No. 3, SEQ ID No. 5, SEQ ID No. 7, SEQ ID No. 9, SEQ ID No. 11, SEQ ID No. 13, SEQ ID No. 15, SEQ ID No. 17, SEQ ID No. 19, SEQ ID No. 21, SEQ ID No. 23, SEQ ID No. 25, SEQ ID No. 27, SEQ ID No. 29, SEQ ID No. 31, SEQ ID No. 33 and SEQ ID No. 35.

The present invention provides spinach plants that exhibit resistance to downy mildew caused by downy mildew, as well as methods of producing, identifying, or selecting a plant or germplasm having a downy mildew resistance phenotype. Such plants include spinach plants comprising a genomic introgression region conferring pest resistance. Further provided are compositions comprising novel polymorphic markers for the detection of plants comprising introgression loci.

The present invention relates to a Spinacia oleracea plant comprising a nucleic acid molecule which when homozygously present provides at least intermediate resistance to Peronospora effusa races Pe: 1, Pe: 2, Pe: 3, Pe: 4, Pe: 5, Pe: 6, Pe: 7, Pe: 8, Pe: 9, Pe: 10, Pe: 11, Pe: 12, Pe: 13, Pe: 14, Pe: 15, Pe: 16, Pe: 17, Pe: 18, Pe: 19 and Pe: 20, wherein said nucleic acid molecule comprises a gene which comprises a coding sequence according to SEQ ID NO: 1 and a gene which comprises a coding sequence according to SEQ ID NO: 2, or a gene which comprises a coding sequence having at least 95.0% sequence identity to SEQ ID NO: 7 and comprises an insertion of sequence motif GAAATA between nucleotides 1235 and 1236 of SEQ ID NO: 7 and a gene which comprises a coding sequence having at least 95.0% sequence identity to SEQ ID NO: 8 and lacks a sequence according to SEQ ID NO: 14, wherein the 95.0% sequence identity is over the part of SEQ ID NO: 8 without the lacking sequence, or genes comprising the corresponding genomic sequences or genes encoding a protein having an amino acid sequence according to SEQ ID NO: 3, and a gene encoding a protein having an amino acid sequence according to SEQ ID NO: 4, or genes encoding proteins showing 95% sequence identity thereto. The invention further relates to a plant carrying the nucleic acid molecule and to methods of selecting, producing and growing such plants.

The present invention relates to an allele designated alpha-WOLF 31 which confers resistance to at least one Peronospora effusa race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that comprises in its amino acid sequence: a) the motif "MAEIGYSVC" at its N-terminus; and b) the motif "KWMCLR"; and wherein the protein has an amino acid sequence that in order of increased preference has at least 97% sequence similarity to SEQ ID NO: 11. The allele when present in a spinach plant confers complete resistance to at least Peronospora effusa race Pe:1, Pe:2, Pe:4, Pe:5, Pe:6, Pe:7, Pe:10, Pe:12, Pe:13, Pe:14, Pe:15, Pe:16, Pe:18, Pe:19, and Pe:20.
