Has the European Barley Powdery Mildew Population Reached Beijing? Not yet!

Popis výsledku v původním jazyce

The virulence of 236 Blumeria graminis f. sp. hordei isolates collected from four Chinese locations was studied in 2003. The determined virulence frequencies were compared with analogical results of the Czech (Central-European) population from 2002. Bothpopulations significantly differ from each other. In the Chinese population, virulences to resistance genes possessed by seven differential varieties were detected. No virulence to the resistance genes Mlg, Mlp, Mlat and to any used resistance genes ofthe Mla locus (except Mla8) was found. There were differences also among Chinese sub-populations but all of them exhibited common (?Chinese?) characteristics. Distinction between the Chinese and European isolates and their low complexity (at least untilnow) does not correspond with the hypothesis of Limpert et al. (2002) about the virulence accumulation of airborne nomadic pathogens in the direction of prevailing winds, i.e. from west to east ("from Paris to Beijing").
