The answers of the breeding yield gain process tasks, that stem from the theory of an ecological - genetic implementation of quantitative traits

Abstract

In the period of 1984-2014 our scientific school (by 2017 - 35 Candidates of Sciences and 12 Doctors of Sciences) evolved a new theory of an ecological - genetic implementation of quantitative traits. The theory is based on the discovery of a new epigenetic phenomenon - change of genes products under a quantitative trait when the limiting factor of the environment changes. It follows by the theory that there are 24 of priority issues and 10 know-how, which can eliminate some “tight spots” of the traditional breeding technologies of a yield gain. The methods of elimination of 16 “tight spots”, that are experimentally well-tried on many agricultural plants, are described in the paper and the perspective of new varieties in Breeding phytotron creation, in which it is quite possible to create any dynamics of limiting factors of the environment for typical years of any region of globe, is demonstrated.
