Virulence phenotypes of Blumeria graminis f. sp hordei in South Africa

Popis výsledku v původním jazyce

Virulence analysis of 224 isolates of Blumeria graminis f. sp. hordei (barley powdery mildew) from South Africa was performed. The isolates were collected from eight fields and a greenhouse in 2004 and 2007. The isolates were tested for virulence on a set of 20 differential varieties. All isolates were virulent on the resistance genes Mla8 and Ml(Ch) and avirulent for the resistance genes Mla3, Mla6, Mla7, Mla9, Mla13, Mla23, Mlp1 and MlaN81. Virulence frequencies of field isolates for the resistance genes Mla12 + MlaEm2, Mlat, Mla22, Mlk1 and Mlh were 52.9-99.5 % and for Mla1 + MlaAl2, MlLa, Mlra, Mlg + MlCP and Ml(Ru2) were 0.5-23.5 %. In total, 46 pathotypes were detected in the field and seven other pathotypes in the greenhouse. Only nine pathotypes were found in both years, but they included 61.8 % of the isolates. The predominant pathotype represented 15.9 % of the isolates, and was the only one common to all three field populations. The average relative virulence complexity per
