| Description
| - Byly zjišťovány frekvence virulencí ke genům odolnosti obsaženým v odrůdách ječmene ozimého. Náhodné vzorky populace patogena byly získány odchytem konidií ze vzduchu nad územím České republiky pomocí mobilní verze lapače spor. Bylo použito celkem 14 diferenciačních odrůd, které obsahují 18 z 20 dosud identifikovaných genů odolnosti, obsažených v odrůdách ječmene ozimého. Byly zjištěny vysoké frekvence virulencí (85-100%) k většině genů odolnosti. Nižší frekvence virulencí (14.1-40.1%) byly zjištěny jen k třem dosud nepopsaným genům odolnosti [Mlu(Va), Mlu(Dt) a Mlu(Ca)]. Je diskutována důležitost odolnosti odrůd ječmene ozimého nejen z hlediska předcházení ztrátám na výnose a kvalitě produkce, ale také s ohledem na omezení rychlosti adaptace patogena ke genetickým odolnostem obsaženým v komerčních odrůdách ječmene ozimého i jarního, jakož i s ohledem na nutnost zvýšení efektivnosti vynakládaných prostředků na ochranu ječmene před napadením padlím travním.

- Virulence frequencies to powdery mildew resistance genes possessed by winter barley cultivars were studied. Random samples of the population were obtained from the air by means of a mobile version of a jet spore sampler mounted on the car roof. Conidia were sampled by driving across the Czech Republic. Fourteen differentials, carrying 18 out of 20 currently identified resistance genes present in winter barley cultivars, were used. High virulence frequencies (85?100%) to most resistance genes were found. Lower virulence frequencies (14.1?40.1%) were found to the three resistance genes only [preliminary designated Mlu(Va), Mlu(Dt) and Mlu(Ca)] that have not been described yet. The importance of resistance of winter barley cultivars is discussed with respect to limiting the speed of the pathogen adaptation to genetic resistances possessed by commercial cultivars of both winter and spring barley and necessity of increasing the effectiveness of costs for powdery mildew control in barley.
