Název v původním jazyce

Mapping of resistance genes to powdery mildew in barley

Popis výsledku v původním jazyce

The introduction of resistance genes to powdery mildew present in two accessions of Hordeum v. spontaneum into H. vulgare was performed by the cross with the variety Tiffany. Resistance tests on plants of F2 generation revealed the segregation ratio 15 1in Tiffany x PI354949 and 3 : 1 in Tiffany x PI466495, which indicated presence of two and one dominant resistance genes, respectively. To identify individual R genes, technology of microsatellite DNA markers and linkage recombination analysis was applied. One of resistance genes in PI354949 was determined to be located in Mla locus linked with Bmac0213 (25.0 cM in distal position) and the other on chromosome 7H linked with Bmag0507 (14.0 cM in proximal position). In PI466495, R gene was linked with Bmac0213 (8.4 cM in distal position) and it is also located in Mla locus. The aim of this work is fine-mapping of the promising gene located on 7H chromosome and identification of tightly linked DNA markers for marker assisted selection.
