| Abstract | The purpose of our research was to determine the indicators of homeostaticity, selection value and variability of wheat spelled samples according to grain quality indicators with the aim of differentiating them according to the level of adaptive potential. The determination of adaptability indicators was carried out during 2015–2021 in the conditions of the Uman National University of Horticulture. The object of research was 25 samples of spelled wheat created by interspecies hybridization with common wheat by university scientists. Analysis of the results of determining the weight of 1000 grains showed a significant difference in this indicator in years with limited and optimal conditions. The range of variability according to individual genotypes was the lowest in samples 25, 1786 and 1817 (4.1 g), and the highest in sample 124 (8.7 g). By gluten content, samples 40 (62.1 %), 76 (52.3 %), 86 (53.2 %), 179 (46.7 %), 1559 (43.8 %) and 1817 (44.7 %) significantly exceeded the standard. Samples 40, 76, and 86 had high homeostaticity and selection value. Samples 76, 86, 179, 1559, 1691, 1721, 1786, and 1817 significantly exceeded the standard in terms of protein content. High homeostaticity and selection value in terms of protein content in grain was recorded in sample 40. Statistical analysis of the results of the study of wheat spelled samples for homeostaticity and selection value for grain quality indicators made it possible to differentiate genotypes according to their adaptive properties. The analysis of adaptive features and selection value according to the set of grain quality indicators made it possible to single out sample 40, which has a high selection value according to the main indicators of grain quality and significantly exceeds the standard for the content of protein and gluten in grain. | ||
