Resistance to powdery mildew (Blumeria graminis (DC.) E. O. Speer f.sp. tritici Em. Marchal) in Aegilops crassa Boiss., Ae. ventricosa Tausch, Ae. biuncialis Vis., Ae. triuncialis L. and Ae. cylindrica Host was tested at the stage of primary leaves in the years 2000 and 2001. All plants of Ae. ventricosa, Ae. biuncialis and sample No. 9 of Ae. cylindrica repeatedly showed a susceptible reaction after being inoculated by all powdery mildew isolates used. In contrast, plants of Ae. crassa, sample No. 8 of Ae. cylindrica and all samples (No. 13, 21, 22, 24 and 26) of Ae. triuncialis were resistant to all isolates. Samples No. 5, 6, 7, 19 and 23 of Ae. cylindrica contained resistant and susceptible plants in both years. Virulence to these samples ranged from 3% to 18%. Cluster analysis using DNA microsatellite markers showed that the accessions are arranged in groups based on taxonomic relationship but not on basis of resistance. Plants susceptible to powdery mildew at the juvenile stage showed satisfactory adult plant resistance.
