Экологическая пластичность генетически полиморфных образцов яровой мягкой пшеницы

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.
