摘要

During 4 years, 27 cultivars and breeding lines of winter wheat (Triticum aestivum) were tested in small plot experiments for resistance to powdery mildew fungus. The most resistant were Frimegu, RE9607, Runal, Asset, Folke and Wasmo. The cultivars Asta (Pm2,6) and Vlasta (Pm2,6 and another not determined specific gene or minor genes of resistance) fall into resistant cultivars. It seems that the specific genes of resistance Pm2 and Pm6 are still very effective against the present Czech population of powdery mildew on wheat. Resistance of the cultivars Hereward and Tarso, having the gene of resistance Pm8, can be ascribed to an additional undetermined gene that is effective only in mature plants. The cultivars Mikon and Ramiro with partial resistance had a higher infection type and disease severity than resistant cultivars, but lower disease severity than the susceptible cultivar Kanzler.Keywords:Triticum aestivum; powdery mildew; disease severity; resistancedownload PDF Impact factor (Web of Science – Thomson Reuters) 2016: 0.742
