摘要：

Fifteen powdery mildew resistance genes and the gene MlaN81 derived from 'Nepal 81' were found in 76 Czech and Slovak spring and winter barley cultivars when tested for reaction to a set of powdery mildew isolates. Nine cultivars ('Donum','Expres', 'Jubilant','Orbit', 'Primus', 'Progres', 'Stabil', 'Vladan' and 'Zlatan') are composed of lines with different resistance genes. The Mlat gene is present in nine cultivars and was transferred from the Anatolian landrace 'A-516'. The resistances derived from 'KM-1192' and 'CI 7672' were identical and designated Ml(Kr). Five winter barley cultivars possess the Ml(Bw) resistance. The winter barley line 'KM-2099' carries the mlo gene. The parental cultivar 'Palestine 10' was also tested in which the genes Mlk1, MlLa were identified. The German cultivar 'Salome', a parent of seven cultivars tested, probably carries the gene MlLa in addition to mlo and Mla7. The gene mlo6 may be present in the cultivar 'Heris'. Most of the results were confirmed by the pedigrees of the cultivars.
