Název v původním jazyce

Investigation of the wild barley germplasm collection for powdery mildew resistance

Popis výsledku v původním jazyce

In 1997 and 1998, in total 972 spring accessions of wild barley were studied. The accessions originate from the Mediterranean region and are housed at the USDA-National Small Grains Collection Aberdeen, USA. In spring form of wild barley 225 accessions were resistant to all 22 European powdery mildew pathotypes and showed also high resistance in the field. In 1999, we started to study the winter part of wild barley. Out of 364 winter barley accessions tested in the greenhouse, 76 accessions were resistant to four pairs of pathotypes in the greenhouse as well as in the field. The collection we studied showed its richness and diversity in powdery mildew resistance. This is a result of long-term co-evolution of wild barley and the pathogen in the Mediterranean region, and particularly in Israel, where most accessions originated. It is apparent that the collection provides a sufficient amount of genetic resources for breeding new barley cultivars resistant to powdery mildew.
