Identification of resistance genes against powdery mildew in four accessions of Hordeum vulgare ssp. spontaneum

Original language description

Four newly detected accessions of wild barley (Hordeum vulgare ssp. spontaneum) resistant to powdery mildew caused by Blumeria graminis f. sp. hordei were studied with the aim of finding the number of genes/loci conferring the resistance of individual accessions, the type of inheritance of the genes and their relationships to the Mla locus. F2 populations after crosses between the winter variety Tiffany and four wild barley accessions and use of microsatellite DNA markers were focused on the identification of individual resistance genes/loci by means of their chromosomal locations. In PI466495, one locus conferring powdery mildew resistance was identified in highly significant linkage with the marker Bmac0213. This location is consistent with the knownlocus Mla on chromosome 1HS. In the other three accessions the resistance was determined by two independent loci. In PI466197, PI466297 and PI466461, one locus was identified on chromosome 1HS and three new loci were revealed on chromoso

Identifikace genů odolnosti k padlí travnímu u čtyř zdrojů Hordeum vulgare ssp. spontaneum

Czech description

Čtyři nově identifikované zdroje odolnosti divokého ječmene Hordeum vulgare ssp. spontaneum k padlí travnímu (původce Blumeria graminis f. sp. hordei) byly studovány s cílem zjištění počtu genů/lokusů determinujících odolnost u jednotlivých zdrojů, typ dědičnosti genů a jejich vztah k lokusu Mla. Populace F2 po křížení ozimé odrůdy Tiffany se čtyřmi zdroji odolnosti a mikrosatelitové DNA markery byly použity k lokalizaci jednotlivých genů odolnosti na chromozomech ječmene.
