    Virulence and diversity of Blumeria graminis f. sp. hordei in Israel and in the Czech Republic.

  • Original language description

    309 isolates were obtained from three natural populations of Blumeria graminis f. sp. hordei occurring on wild barley at two locations in Israel during 1997 and 1999. Their virulence frequency was determined on 32 differential lines. No isolate was virulent on the differential lines possessing the genes Mla13, mlo, Mlf1, and Mli, and conversely no isolate was avirulent on the differential lines possessing the genes MIRu2, MILa, Mlh, Mla8, Mla25, and Mlj. The frequencies of isolates overcoming the genesMlg, Mla7, and Mla27 were 0 to 16% at individual locations; frequencies of isolates overcoming the genes Mla9, Mla17, and Mla18 ranged from 37 to 78%, and frequencies of virulences to genes Mla1, Mla3, Mla6, Mlp1, Mlat, Mla12, Mlra, Mlk1, Mla19, Mla20, Mla26, Mla28, Mla29, Mla30, Mla32, and mlt1 were 79 to 99%. Based on examination of 376 isolates collected in the same years from the Czech Republic, these populations differed greatly from the Israeli ones.

    Virulence a diverzita Blumeria graminis f. sp. hordei v Izraeli a v České republice

  • Czech description

    Na dvou lokalitách v Izraeli bylo v letech 1997 a 1999 získáno 309 izolátů ze tří přírodních populací patogena Blumeria graminis f. sp. hordei vyskytujícího se na divokém ječmeni Hordeum vulgare subsp. spontaneum. Frekvence jejich virulence byla zjišťována na 32 diferenciačních liniích. Žádný izolát nebyl virulentní k diferenciačním liniím obsahujícím geny Mla13, mlo, Mlf1 a Mli, a naopak žádný izolát nebyl avirulentní k diferenciačním liniím obsahujícím geny MIRu2, MILa, Mlh, Mla8, Mla25 a Mlj. Frekvence izolátů překonávajících geny Mlg, Mla7 a Mla27 byla na jednotlivých lokalitách 0 až 16%; frekvence izolátů překonávajících geny Mla9, Mla17 a Mla18 kolísala od 37 do 78%, a frekvence virulencí ke genům Mla1, Mla3, Mla6, Mlp1, Mlat, Mla12, Mlra, Mlk1,Mla19, Mla20, Mla26, Mla28, Mla29, Mla30, Mla32 a mlt1 dosahovala 79 až 99%. Na základě studia 376 izolátů získaných ve stejných letech v České republice se tyto populace značně lišily od izraelských populací.
