Název v původním jazyce

Identification of resistance genes against powdery mildew in wild barley PI284752 by DNA markers

Popis výsledku v původním jazyce

A newly detected accession of wild barley (Hordeum vulgare ssp. spontaneum) resistant to powdery mildew caused by Blumeria graminis f. sp. hordei was studied with the aim of finding the number and identity of genes conferring the resistance. Therefore, F2 population derived from a cross between the winter variety Tiffany and the wild barley accession PI284752 consisted of 449 plants was established. Use of DNA markers was focused on the identification of individual resistance genes by means of their chromosomal locations. The number of plants in the two phenotypic categories (427 resistant and 22 susceptible) found in F2 population was compared with a theoretical Mendelian segregation ratio by a chi-square test and a two-locus model of resistance was shown by this genetic analysis (chi-square=1.37). In PI284752, dominant alleles of two independent genes were present; the allelism test indicated that one gene was located at the Mla locus. All parental plants of PI284752 showed the highe
