| Abstract: | It is shown that the genetic growth of a grain yield (GY) is provided with two factors: a biological yield (BY) and a harvest index (HI). Depending on the ecological conditions their contribution can be both positive and negative. The genetic diversity BY is a result of the genotype-environment interaction. The interaction of genotypic factors with ecological conditions permits to consider genetic progress GY as two-step-by-step process, first of which is a creation of the corresponding ecological conditions which provide advantages to new genotypes, and second is a selection of these new genotypes. |
