ADAPTIVE POTENTIAL AND PROSPECTS OF BREEDING USE OF SPRING VETCH COLLECTION SAMPLES
Abstract
The results of the longstanding studies of spring vetch collection samples of N.I. Vavilov Poltava State Agricultural Experimental Station, their response to changes of environmental conditions, an analysis of the indices of ecological plasticity are presented in the paper. As a result of the conducted researches, the forms characterized by a high genotypic effect and a medium plasticity level (Ri) have been isolated. These forms successfully combine relatively high productivity potential with relatively stable manifestation of it and as initial material are of the most interest for the adaptive breeding. The forms with a high regression coefficient (ecological plasticity) have the “internal” reserve for productivity increase which enables them to implement their genetic potential at the improvement of vegetation conditions. These forms may be valuable for the use in intensive breeding technologies or in the breeding of the varieties oriented toward such technologies.
