Virulence frequency to powdery mildew resistances in winter barley cultivars

Popis výsledku v původním jazyce

Virulence frequencies to powdery mildew resistances in winter barley cultivars were studied in 2007 and 2008. Random samples of the air populations were obtained by means of a mobile version of a jet spore sampler. Conidia were sampled by driving acrossthe Czech Republic. In total 349 isolates were studied and 17 differentials were used. The virulence frequencies to specific resistances of given cultivars showed wide range from 0% to 100%. Nine differentials were used to distinguish 134 pathotypes, ofwhich 32 representing 63.9% of isolates were detected in both years. The pathotype 773 was most abundant that broke down the resistance of eight differentials. In 2008, lower virulence frequencies to all differentials, and thus lower population complexity, were determined, which may be caused by different regional origins of the isolates examined. Importance of the study of the given pathogen population is discussed in terms of successful breeding resistant barley cultivars.
