The work is devoted to the study of winter hardiness and its phenotypic stability of breeding lines of winter soft wheat under varying environmental conditions. The factors influencing the winter hardiness of the crop in the research area are considered. A fairly high level of winter hardiness of the studied genotypes of winter soft wheat was established - 3.8-4.7 points. High ecological buffering in terms of phenotypic stability of winter hardiness was revealed for breeding lines of winter soft wheat number 7, 13, 23, 32 - SF = 1.19-1.28. Of interest for breeding practice is the breeding line of winter soft wheat number 13, which combines a high level of winter hardiness - 4.6 points and the highest value of phenotypic stability of this indicator - SF = 1.19.
