Sažetak

Over 1500 wheat sources of resistance were tested under conditions of artificial infection and chosen 7 genotypes werw mutually crossed by using the scheme of partial diallel. Sources of resistance markedly differed in level of resistance, which ranged from 0,65 to 3,89(rating scale 0-5). Improving the level of resistance was obtained in F1 generation, as well as in F1 x F1 crosses in the several combinations in comparison withtheir components. Additive gene effect(i.e. minorgene effects) and dominance were noticed.The highest level of resistance was found in F1 generation snd in F1 x F1 crosses of combinations involving sources of resistance Bizel and Poncheau.
