Spinach Cultivars Resistant to Peronospora farinosa f. sp. spinaciae Isolate SAI-2

Abstract

Spinach cultivars reaction to Peronospora farinosa f. sp. spinaciae isolate SAI-2, suspended race numbering, obtained from Saitama Prefecture, Japan in 2010 were studied. It was suggested that commercial cultivars resistant to race 8 had also potential for resistance against the pathogenic strain involving isolate SAI-2.
