Mathematical modelling in plant breeding. II. Algorithms for control of genetic-breeding improvement of economically valuable properties in self-pollinators

The authors considered the brand new approaches to choose the breeding pairs (varieties) for crossing and prediction of eco-genetic picture of new variety. The algorithm of control of breeding process on the basis of mathematical model for «genotype—environment» interaction was proposed, which consists in successive choose the variants of mutually complementary eco-genetic character of potential parents and prediction of resultant quantitative breeding determinants. The choose of the variants is performed until a required degree of coincidence between predictable and specified breeding determinants occurs. Under the control of ecological factors such choose is supplementing by optimization of environment parameters, and it provides the maximal usage of eco-genetic potential and the increase of reliability of identification of progeny genotypes on their phenotypes in the sequel.
