Abstract

A collection of common wheat cultivars grown in Poland were analyzed for resistance to powdery mildew disease by using eleven differential isolates of Erysiphe graminis f. sp. tritici (Blumeria graminis). Among a total of 69 accessions, 48 cultivars possessed resistance which is attributed to known resistance genes present either individually or in a combination. Four cultivars were resistant to all the isolates used and another four cultivars revealed race-specific resistance which does not correspond to the response patterns of previously documented resistance. Resistance genes Pm2 and Pm6 in a combination were most widely distributed, and genes Pm3d, Pm4b, Pm5 and Pm8 were also postulated.
