    IGenetic analysis of thirteen accessions of Hordeum vulgare ssp. spontaneum resistant to powdery mildew

  • Original language description

    Thirteen accessions of wild barley (Hordeum vulgare ssp. spontaneum) resistant to powdery mildew caused by the fungus Blumeria graminis f. sp. hordei were studied with the aim of determining the number of resistance genes and their allelic relationshipsto the Mla locus on the short arm of chromosome 1H. In five accessions (PI391130, PI466193, PI466200, PI466495 and PI466510), the resistance was caused by one gene, in seven accessions (PI354949, PI391081, PI466158, PI466197, PI466211, PI466297 and PI466461) by two independent genes and in PI301004 by three independent genes. The type of inheritance of all analysed genes except two was dominant or semi-dominant; only one of two genes in PI391081 and PI466297 was recessive. Allelism tests confirmed thatin 10 accessions one gene was allelic with the Mla locus, and in three accessions (PI391081, PI466193 and PI466297) the resistance genes were different from the Mla locus.

    Genetická analýza třinácti zdrojů odolnosti k padlí travnímu Hordeum vulgare ssp. spontaneum

  • Czech description

    Třináct zdrojů divokého ječmene (Hordeum vulgare ssp. spontaneum) odolných k padlí travnímu (původce Blumeria graminis f. sp. hordei) bylo studováno s cílem zjištění počtu genů determinujících odolnost a jejich alelismus s lokusem Mla. U pěti zdrojů (PI391130, PI466193, PI466200, PI466495 a PI466510) byla odolnost determinována jedním genem, u sedmi zdrojů (PI354949, PI391081, PI466158, PI466197, PI466211, PI466297 a PI466461) dvěma nezávislými geny a u zdroje PI301004 třemi nezávislými geny. Odolnost byla u všech analyzovaných genů kromě dvou determinována dominantní alelou, pouze u dvou zdrojů PI391081 a PI466297 recesivní alelou. Test na alelismus potvrdil, že u deseti zdrojů byl vždy jeden gen alelní s Mla a u tří zdrojů (PI391081, PI466193 a PI466297) byly geny nealelní s Mla.
