ECOLOGICAL PLASTICITY OF GENETICALLY POLYMORPHIC SAMPLES OF SPRING BREAD WHEAT
In the article data on the influence of genetically polymorphic strains on yield stability of spring bread wheat in Ob' forest-steppe of Altai territory are given. It was established that the mixture of a limited number of morphologically different genotypes as a breeding approach did not effect the size and the stability of wheat yield. Genetic heterogeneity of segregated hybrid generations provides them with advantages in the general adaptability in a number of environments compared to parental forms.
