| Abstract | The aim of the research was to analyze the level of adaptability of winter spelt wheat samples created by hybridization of Triticum aestivum L. × Triticum spelta L. and to identify promising genotypes for their involvement in the selection process of creating highly adaptive crop varieties. According to the results of the assessment of the grain yield of winter spelе wheat samples, it was established that it varied in the range of 3.97–6.45 t/ha on average for 2018–2020. Samples 1645 (6.45 t/ha), 1817 (5.81 t/ha), 1559 (5.78 t/ha) and 1725 (5.70 t/ha) were distinguished by the highest yield. Calculations of ecological plasticity of the studied samples showed that winter spelе wheat samples 1817 (bі = 1.37), 66 (bі = 1.27), 1786 (bі = 1.17), 40 (bі = 1.15), 47 (bі = 1.11), 1559 (bі = 1.12), 1725 (bі = 1.13), 1755 (bі = 1.07) are highly plastic. Calculations of environmental stability showed that the most stable samples are 15 (S2dі = 0.013), 95 and 1695 (S2dі = 0.014), 1691 (S2dі = 0.011), 1694 (S2dі = 0.016), 13 and 1721 (S2dі = 0.017). High homeostaticity was recorded in samples 95 (Hom = 266.1), 155 (Hom = 238.3), 1691 (Hom = 283.0), 1695 (Hom = 342.2), 1725 (Hom = 241.0), 1755 (Hom = 230.1), 1817 (Hom = 262.4). samples 76 (Sc = 6.5), 95 (Sc = 6.7), 108 (Sc = 6.5), 155 (Sc = 6.5), 1674 (Sc = 6.4) had the highest selection values , 1691 (Sc = 6.7), 1695 (Sc = 7.5), 1725 (Sc = 7.0), 1817 (Sc = 7.4). Samples of winter spelled wheat 66, 124, 1786, 1817 characterized by high ecological plasticity (bі = 1.17–1.27), homeostaticity (Hom = 131.1–262.4) and breeding value (Sc = 6.0–7.4) were selected. It is expedient to use the obtained samples as source material in selection for adaptability. | ||
