This article presents data on the level and frequency of positive transgressions for the production elements of winter common wheat. It was established that genotypic factor is of great importance in the expression of transgressive potential of hybrid combinations. Were obtained the date on the level of dependency for the relations of transgressions with the degree of dominance, genetic distances of parents, also on the distribution of phenotypic classes in parental and segregating F2 populations.
