Özet

Two mildew populations on wild barley were sampled for cleistothecia in western Turkey at the end of May in 1333. Testing the ascospore descendants on a differential, representing 23 monogenic mildew resistances, gave mean virulence complexities of 11.4 and 12.4, respectively, for the pathogen populations. Differences between the two mildew populations were indistinct, when compared for the existence of virulences. Examining the pathotype composition revealed a clear difference between the populations. In this respect, the mildew populations were highly heterogeneous. The predominant pathotype had a frequency of nearly 18 % in one population of 31 pathotypes, while its proportion was approximately 11 % in the second population with 61 pathotypes.
