Pathogenicity of Blumeria graminis f. sp. hordei in New Zealand in 1997

Popis výsledku v původním jazyce

The pathogenicity of 137 isolates of Blumeria graminis f. sp. hordei originating from five locations in New Zealand was analysed using a differential set of 15 near-isogenic lines (Pallas). The isolates belonged to 14 pathotypes. The pathotypes exhibitedfour to seven virulences, and all possessed Vg, Vra and Vh. They were also avirulent for resistance genes Mla3, Mla6, [Mla7 Mla(No3)], Mla9, Mla13 and Mlk1, but differed by the presence (or absence) of virulences Va1, Va12, VLa, Vat, V(Ru2) and Vp1. Forty-nine isolates (35.8%) belonged to the predominant pathotype 14055. There were considerable differences in the composition of individual sub-populations, which could indicate that the vegetative stage is less important for survival and distribution ofthe pathogen in New Zealand. Direct selection of the pathogen population on host varieties is apparently slower in New Zealand than in Central Europe. Little or no gene flow occurs between the New Zealand and Australian populations.
