Název v původním jazyce

Powdery mildew resistance of Czech and Slovak spring barley breeding lines in variety trials

Popis výsledku v původním jazyce

In 2001-2005, resistance to powdery mildew was studied in 227 Czech and Slovak breeding lines of spring barley included in the pre-registration and registration trials. Seventeen known resistances were identified (Al, Ar, At, HH, Kr, La, Ly, Mlo, N81, Ri, Ru, Sp, St, Tu, We, Mla21, and Mlp1). Unknown resistances were found in 11 breeding lines, of which in five resistance was effective against all used pathotypes of the pathogen. Besides identified resistances, unknown resistances were detected in another three breeding lines. Sixty-five breeding lines (= 29%) exhibited heterogeneity in the examined trait, i.e. they are composed of components with different resistances to powdery mildew. Comparison of current results with the previous ones shows the considerable increase in the proportion of breeding lines carrying the resistance Mlo (72%), a namely off the resistances located at the Mla locus, particularly Ru.
