    Powdery mildew resistance of winter barley varieties in Czech Official Trials.

  • Original language description

    In 1996?2005, resistance to powdery mildew was studied in 167 winter barley varieties (of them 83 two-rowed and 84 six-rowed, 45 Czech and 122 foreign ones) included in the Czech Official Trials in that period. Seventeen known resistances to powdery mildew were identified (Ar, Bw, Di, Dr, Dt, Ha, HH, Ch, IM9, La, Lu, Ly, Ra, Ru, Sp, St and We). Unknown resistances were found in 25 varieties, in six of which (= 3.6% of all the examined set) they were effective to all used pathotypes of the pathogen. Sixvarieties exhibited heterogeneity in the examined trait, i.e. they are composed of lines with different resistances to powdery mildew. The most frequent resistances in the set were Ra, which was detected in 89 varieties (= 53%), and Bw was found in 30 varieties (18%). The resistances Sp, Ly, Ha, HH and Ch were also frequent. However, the frequency of the last three resistances cannot be quantified since we were not able to identify these resistances during the whole examined period.

    Rezistence k padlí travnímu u odrůd ozimého ječmene ve státních odrůdových zkouškách.

  • Czech description

    V letech 1996?2005 byla studována rezistence k padlí travnímu u 167 odrůd ozimého ječmene (z toho 83 dvouřadých a 84 šestiřadých, 45 českého a 122 zahraničního původu) zařazených v tomto období do Státních odrůdových zkoušek. Bylo zjištěno 17 známých rezistencí k padlí travnímu (Ar, Bw, Di, Dr, Dt, Ha, HH, Ch, IM9, La, Lu, Ly, Ra, Ru, Sp, St a We). Neznámé rezistence byly nalezeny u 25 odrůd, z nichž u 6 (= 3.6% z celého studovaného souboru) byly účinné ke všem použitým patotypům patogena. Šest odrůd bylo ve sledovaném znaku heterogenních, tj. jsou složeny z linií s rozdílnou rezistencí k padlí travnímu. Nejčastěji se vyskytující rezistence v souboru byla Ra zjištěná v 89 odrůdách (= 53%) a Bw ve 30 odrůdách (18%). Časté byly také rezistence Sp, Ly, Ha, HH a Ch. Frekvenci posledních tří rezistencí však nelze kvantifikovat, protože nebylo možné identifikovat tyto rezistence během celého sledovaného období.
