Adaptability of winter wheat samples under the conditions of Western Siberia

The yield data (2017-2021) and adaptability parameters calculated on their basis are presented for highly productive winter wheat samples from the laboratory of Winter Crop Breeding of the Omsk Agrarian Scientific Center (ANC). Line 43/18 showed the highest yield in experiments (5.69 t/ha), was characterized by low variability (7.9%), had the best values of genetic flexibility and homeostaticity, and was also included in the group of samples promising for breeding value. Line 46/19 was distinguished by four adaptability parameters, and lines 26/16, 45/19 and 48/19 were distinguished by three. When ranking the adaptability parameters, it was found that the smallest sum of ranks was inherent in the lines 46/19 (18), 43/18 (19), 45/19 (28), 48/19 (31), 53/17 (31). The noted samples as sources of high adaptability and yield can be used in the selection of winter wheat in the region.
