The paper reports on the results of the study of eleven cultivars and strains of winter soft wheat tested in the conditions of the submontane zone of the Central Caucasus. The average annual yield (2016-2018) varied from 0.66 to 1.05 kg/m2. A comprehensive assessment of the parameters of environmental plasticity and adaptability using various methods was carried out. According to the results of variance analysis, the genotypes of the studied samples (the “cultivar” factor) had the highest impact on the overall variability of productivity – their proportion was 50%. The proportion of variability caused by the influence of environmental conditions (the “year” factor) was 26.5%. To identify adaptive genotypes by productivity, regression, and correlation analyses were performed and various selection indices were calculated.
