Peculiarities of manifestation of the degree of transgression in populations of winter bread wheat for inheritance of breeding value elements

Abstract

The objective of this research was to identify the characteristics of transgressions degree in terms of main spike productivity in populations of the second and third generation of winter soft wheat. The material for the research comprised 30 hybrid combinations created through the use of a full diallel crossing scheme of six winter soft wheat varieties carrying wheat-rye translocations (WRT). There were: 1AL.1RS (Zolotokolosa, Columbia, Ekspromt), 1BL.1RS (Svitanok Myronivskyi, Legenda Myronivska, Kalynova). The involvement of the local gene pool of winter bread wheat-rye translocations represents a highly effective measure that can serve as the next stage of significant improvement of varieties in terms of yield.
