Abstract
Powdery mildew, caused by Blumeria graminis f. sp. hordei the windborne fungal pathogen, is one of the most economical important barley foliar diseases in harvest. Breeding for resistance is the important direction for breeders. Introducing and pyramiding new resistance genes to cultivars leads to reducing the impact disease to yield. Barley landraces are rich sources of genetic diversity, but still low operated. Disclosure this materials open new dimension for breeders. Barley landrace Bgh255-3-3, resistant to broad spectrum to B. graminis isolates was crossed with susceptible cultivar Manchurian. The main aim was to define new resistance locus. To achieve this goal; 100 molecular SSR markers was tested in bulk segregants analysis (BSA) method and high throughput diversity array technology (DArT) was applied to F2 population. Identifying new sources of resistance and new molecular markers associated to resistance genes provide possibility to use marker-assisted selection (MAS). This work has practical importance by broadening barley gene pool available to breeders.
