Evaluation of indicators of ecological adaptivity of winter soft wheat assortment in the forest-steppe of the Middle Volga region

Abstract

A comparative characteristic of 16 varieties of winter soft wheat cultivated in the Ulyanovsk region is given in terms of yield and various indicators of environmental adaptability: the value of the yield potential realization, plasticity, stability, homeostaticity, stress resistance, adaptability coefficient. The influence of external conditions (77.8%), varieties (2.7%) and interaction of factors (13.3%) on the grain yield of winter soft wheat was established.
