Description
  • 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.

  • Byla prostudována odolnost k padlí travnímu ve 227 českých a slovenských liniích ječmene jarního zařazených v uvedeném období do předregistračních a registračních zkoušek. Bylo identifikováno 17 známých odolností k padlí travnímu (Al, Ar, At, HH, Kr, La, Ly, Mlo, N81, Ri, Ru, Sp, St, Tu, We, Mla21 and Mlp1). V 11 šlechtitelských liniích byly zjištěny neznámé odolnosti, z toho v pěti liniích byly tyto odolnosti účinné vůči všem použitým patotypům daného patogena. V 65 šlechtitelských liniích (= 29%) byla zjištěna heterogenita sledovaného znaku, tzn. že jsou tvořeny komponentami s rozdílnými odolnostmi k padlí travnímu. Porovnáním stávajících výsledků s předchozími bylo zjištěno významné zvýšení podílu šlechtitelských linií, obsahujících odolnost Mlo (72%), a to na úkor odolností lokalizovaných v Mla lokusu, zvláště Ru. Sledovaný soubor se vyznačuje vysokým podílem šlechtitelských linií odolných ke všem použitým domácím patotypům daného patogena (78%), ale nízkou diverzitou sledované odolnosti. (cs)
