Abstract: ur experimental evidence suggests that of all the winter wheat cultivars tested only 6.3% possessed complex resistance to powdery mildew (PM) and tan spot (DTR). The cultivars susceptible to both diseases accounted for 50%. The genotypes with only PM resistance were more numerous (29.2%) than those with only DTR resistance (12.5%). Maximal severity of DTR was scored 9, while that of PM - 7 (using a 1-9 scale). The mean of area under disease progress curve (AUDPC) for all cultivars was 188 for PM and 516 for DTR. The cultivars ‘Aperitif ’, ‘Torild’, ‘Striker’, ‘Tulsa’, ‘Director’, ‘Dromos’, ‘Symbol’, ‘Tuareg’ and ‘Brilliant’ possessed the highest complex resistance to both diseases. Maximal severity of PM for these cultivars was scored 4, DTR - 5. The maximal AUDPC for PM was 69 and for DTR 342.
