The present invention relates to a spinach plant comprising an R15 resistance conferring allele, wherein said allele confers resistance to at least Peronospora farinosa f. sp. spinaciae races Pfs:1, Pfs:2, Pfs:3, Pfs:4, Pfs:5, Pfs:6, Pfs:9, Pfs:11, Pfs:12, Pfs:13, Pfs:14, Pfs:15 and isolate UA1014 and does not confer resistance to Peronospora farinosa f. sp. spinaciae race Pfs:7, and wherein said allele is as found in a plant grown from a seed of which a representative sample was deposited with the NCIMB under NCIMB accession number 42466. When the spinach plant comprises the R15 resistance conferring allele heterozygously said allele further confers at least intermediate resistance to Peronospora farinosa f. sp. spinaciae races Pfs:8 and Pfs:10.
