2001
Delalic, Z.
It was collected 43 samples and 172 isolates were analysed. Multiplication inoculum was founded on susceptible cultivar Little Club. For analysis virulence of pathotypes were used 20 cultivars and isogenic lines with know genes of resistance. The results confirmed the supposition that the variability of powdery mildew population in north-west part of Bosnia (Bosnia and Herzegovina) is very expressed and there are pathotypes with great number of virulence genes. In this investigation 129 pathotypes were identified. In pathotypes frequency of virulence genes ranged from 8.7-98.2%.
