The present invention relates to spinach plants displaying resistance to Peronospora effusa. The present invention also relates to seeds and parts of said plants, for example leaves and heads. The present invention further relates to methods of making and using such seeds and plants. The present invention also relates to genetic sequences associated with said resistance to Peronospora effusa and to molecular markers associated with said genetic sequences.

The present invention relates to an allele designated alpha-WOLF 15 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 at its N-terminus; and b) the motif KWMCLR; and wherein the LRR domain of the protein has in order of increased preference at least 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID No:10. The allele when homozygously present in a spinach plant confers complete resistance to Peronospora farinosa f. Sp. spinacea races pfs:1, pfs:2, pfs:3, pfs:4 and pfs: 5, pfs:6, pfs:8, pfs:9, pfs:11, pfs:12, pfs:13, pfs:14, pfs:15, pfs:16 and isolates UA1014 and US1508, and confers intermediate resistance to pfs:10, and does not confer resistance to pfs:7.
