Changes in the population of Blumeria graminis f.sp. hordei in the Czech Republic from 2009 to 2010

Popis výsledku v původním jazyce

Virulences to powdery mildew resistances in barley cultivars mostly carrying unknown resistances were deter -mined in 2009 and 2010. Random spore samples of the airborne pathogen populations originating from winter and spring barley fields were obtainedby means of a mobile version of a jet spore sampler by travelling across the Czech Republic. In total 301 isolates were studied, 55 differentials carrying mostly unknown resistances were used and 80 pathotypes were found, of which 26 representing 73.1% of isolates were detected in both years. Viru -lence frequencies showed a wide range from 0% to 100%. Complexity of the 2010 population slightly increased, mostly due to increasing frequencies of virulence to new resistances, whereas the complexity of virulences to resistances in most other differentials decreased. Pathotype 00027 was the most abundant (10.0%). Diversity of the 2010 population considerably increased due to changes in virulence frequencies.
