Newly discovered genes for resistance to powdery mildew in the subtelomeric region of the short arm of barley chromosome 7H

Original language description

Two dominant genes for resistance to powdery mildew (caused by Blumeria graminis f.sp. hordei) from the PI296825 and PI466461 accessions of wild barley (Hordeum vulgare subsp. spontaneum) were identified close to the subtelomeric region of the short armof chromosome 7H. Genetic analyses predicted two resistance loci in F2 populations established from crosses between each of the two accessions and the winter barley (H. vulgare) variety Tiffany. Genetic mapping revealed a highly effective (52% of phenotypic variation) resistance gene from PI296825 located between the markers GBMS192 and GBM1060. In F2 plants exhibiting resistance reaction types (RT) 0 to RT1?2, specific DNA fragments for co-segregating markers were amplified. In plants with RT2 and RT2?3, the resistance was conferred by another unidentified resistance gene. In PI466461, the resistance gene found on the short arm of chromosome 7H was flanked by the markers GBM1126 and GBM1060. Another resistance gene coincided with the M
