Název v původním jazyce

Genetic and molecular analysis of new sources of resistance to mildew in barley (Hordeum vulgare ssp. spontaneum).

Popis výsledku v původním jazyce

Thirteen newly identified resistance sources of wild barley Hordeum vulgare ssp. spontaneum to powdery mildew were studied with the aim to identify the number of genes conferring resistance to powdery mildew, their allelic relationships, their allelism with Mla gene, and the to localise individual genes on barley genetic map. The genetic and the molecular analyses were performed in the segregating F2 populations of crosses between winter barley Tiffany and individual resistance sources. In five resistance sources the resistance was found to be determined by one gene, in seven sources by two independent genes and in one by three independent genes. The mode of inheritance of all analysed genes except one was determined to be dominant or semi-dominant, only one was recessive. Allelism tests confirmed that one resistance gene in all sources was Mla. Apparently, various alleles of Mla often participate in the genetic determination of this trait and the gene belongs to those with the highest
