| Description
| - V letech 2007 a 2008 byla studována frekvence virulencí k odolnostem odrůd ječmene ozimého k padlí ječmene. Náhodné vzorky vzdušné populace patogenu byly získány pomocí mobilní verze lapače spor. Konidie byly odchyceny při průjezdu po trasách vedoucích vybranými oblastmi České republiky. Celkem bylo prostudováno 349 izolátů na 17-ti členném diferenciačním souboru. Byly zjištěny frekvence virulencí ke specifickým odolnostem daných odrůd v širokém rozpětí 0 až 100%. Pomocí vybraných 9 diferenciátorů bylo rozlišeno 134 patotypů. Z nich 32 patotypů, které byly zjištěny v obou sledovaných letech, reprezentovalo 63.9% izolátů. Nejhojnější byl patotyp 773, který překonával odolnost 8 diferenciátorů. V r. 2008 byla zjištěna nižší frekvence virulencí ke všem diferenciátorům a tím i nižší komplexnost populace, což může souviset s odlišným regionálním původem studovaných izolátů. Je diskutován význam studia populace daného patogenu pro úspěch šlechtění odolných odrůd ječmene. (cs)
- 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 across the 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, of which 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.
