Provided herein are spinach plants resistant to Peronospora farinosa and Stemphylium vesicarium, and spinach plants additionally resistant to Cucumber Mosaic Virus (CMV). Also provided herein are genomic fragments providing the present resistances and use thereof for identifying spinach resistant to Peronospora farinosa and Stemphylium vesicarium, and spinach plants additionally resistant to Cucumber Mosaic Virus (CMV). Provided herein are a spinach plant resistant to Peronospora farinosa and Stemphylium vesicarium: including a genomic fragment of Spinacia tetrandra located on chromosome 4 between positions 8255074 and 8620598 of the spinach reference genome, the genomic fragment of Spinacia tetrandra lacking a lethal factor and providing Peronospora farinosa resistance and including a genomic fragment located on chromosome 3 and between positions 1177586 and 1271037 of the spinach reference genome providing Stemphylium vesicarium resistance.

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 relates to an allele designated beta-WOLF 28 which confers resistance to at least one race of Peronospora farinosa (P. farinosa) Peronospora effusa ​ ) wherein the protein encoded by said allele is a CC-NBS-LRR protein comprising in its amino acid sequence: a) at its N-terminus the motif "MAEIGYSVC"; and b) the motif "HVGCVVDR"; and wherein said protein has an amino acid sequence having in order of increasing preference at least 95.5% sequence similarity with SEQ ID NO: 11. When present in homozygous form in a spinach plant, said allele confers full resistance to at least P. farinosa 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 and Pe:13 and does not confer resistance to races Pe:14, Pe:15, Pe:16, Pe:17, Pe:18 and Pe:19.
