The present invention provides a spinach plant having resistance to a broad range of races, a method for producing said spinach plant, and the like. The present invention provides a downy mildew resistant spinach plant having a downy mildew resistance RPF-SK1 gene in at least one allele, wherein in the RPF-SK1 gene: (a) the SNP identified by chr3_1215815 is cytosine, (b) the SNP identified by chr3_1215855 is thymine, (c) the SNP identified by chr3_1216014 is cytosine, (d) the SNP identified by chr3_1216093 is guanine, the SNP identified by chr3_1216094 is guanine, and the SNP identified by chr3_1216095 is adenine, (e) the SNP identified by chr3_1216288 is adenine, or (f) the SNP identified by chr3_1216291 is guanine.
A downy mildew resistant spinach plant having a downy mildew resistance RPF-SK1 gene in at least one allele, wherein
A downy mildew resistant spinach plant that is a downy mildew resistant spinach plant specified in accession number FERM BP-22426, a hybrid plant obtained using the downy mildew resistant spinach plant as a parent, or a progeny of either of these plants.
A method for predicting downy mildew resistance of a spinach plant, or screening downy mildew resistant spinach plants, the method comprising investigating genotypes of at least one SNP selected from the group consisting of chr3_1215815, chr3_1215855, chr3_1216014, chr3_1216093, chr3_1216094, chr3_1216095, chr3_1216288 and chr3_1216291 of a test spinach plant,
