Description	Padlí travní je v České republice nejběžnější chorobou ječmene, a ozimý ječmen hraje v přezimování a reprodukci patogena rozhodující roli. Tato práce byla zaměřena na identifikaci genů rezistence v odrůdách ozimého ječmene pěstovaných v České republice od roku 1971 do 2005. Geny rezistence byly identifikovány metodou postulace. Ve fázi klíčních rostlin bylo 41 odrůd a jedna rodičovská linie testováno na reakci k 32 vybraným izolátům Blumeria graminis f. sp. hordei. Celkem bylo zjištěno 26 spekter rezistence a nalezeno následujících 18 genů rezistence: Mla6, Mla7, Mla8, Mla13, Mla14, MlaMu2, MlaNo3, MlaRu4, Mlg, Mlh, MlLa, Mlra, Ml(Bw), Ml(Ch), Ml(Dr2), Ml(Dt5), Ml(IM9) a Ml(St). Dvě odrůdy (Kiruna a Sorna) byly v reakci na padlí travní heterogenní. Je diskutováno o dalším zdroji Mla13 a možných centrech původu genu Ml(Bw). (cs) Powdery mildew is the most common disease of barley in the Czech Republic and winter barley plays a crucial role in the winter survival and reproduction of the pathogen. This study aimed at identifying resistance genes in winter barley cultivars grown in the Czech Republic from 1971 to 2005. Resistance genes were identified using the method of postulation. Forty-one cultivars and a parental line were tested at the seedling stage for their reaction to 32 selected isolates of Blumeria graminis f. sp. hordei. In total, 26 resistance spectra were detected and the following 18 resistance genes were found: Mla6, Mla7, Mla8, Mla13, Mla14, MlaMu2, MlaNo3, MlaRu4, Mlg, Mlh, MlLa, Mlra, Ml(Bw), Ml(Ch), Ml(Dr2), Ml(Dt5), Ml(IM9) and Ml(St). Two cultivars (Kiruna and Sorna) exhibited heterogeneity for mildew resistance. Another source of Mla13 and a possible centre of origin of Ml(Bw) are discussed.
