Purpose. To analyze lines of competitive testing of soft spring wheat in terms of ecological plasticity and stability using statistical methods of analysis and identify lines with high stability of grain yield. Methods. The studies were carried out during 2018–2020, on the basis of the V. M. Remeslo Myronivka Institute of Wheat NAAS of Ukraine. When considering the results obtained, generally accepted methods of genetic and statistical analysis were used. Results. Evaluation of breeding material in different years makes it possible to obtain information about the characteristics of the reaction of genotypes to changes in environmental conditions. As a result of the studies, it was found that the lines Lutescens 14-32 (bi = 0.59), Erythrospermum 15-32 (bi = 0.44), Lutescens 14-47 (bi = 0.22) were of high plasticity. Calculations of ecological stability indicate that lines are considered stable, the variance of stability is zero or close to zero. From a practical point of view, lines with a combined manifestation of high ecological plasticity and stability are considered valuable. This was the line Erythrospermum 15-32 (bi = 0.44; S2di = 0.01) that indicates its low reaction rate and the ability to provide a consistently high level of yield under any growing conditions. The most valuable are the genotypes that combine a low level of the coefficient of variation, high homeostaticity and breeding value, which include the lines Erythrospermum 15-32 (Hom = 206.42, Sc = 4.11), Lutescens 14-47 (Hom = 98.41, Sc = 3.91), Erythrospermum 17-08 (Hom = 78.57, Sc = 3.76), Erythrospermum 14-65 (Hom = 54.84, Sc = 3.75), Lutescens 14-32 (Hom = 54.60, Sc = 4.17), Lutescens 14-13 (Hom = 35.60, Sc = 3.78), Lutescens 14-48 (Hom = 46.66, Sc = 3.58). Conclusions. The evaluation of breeding material is of great importance when creating new high-performance varieties with adaptive potential. The method for assessing ecological plasticity and variants of its stability made it possible to differentiate wheat lines of soft spring competitive testing by their response to changes in growing conditions. For a more optimal selection of breeding material in terms of ecological plasticity and stability, breeding programs should take into account ranked estimates of genotypes.

“…Since the weather conditions become more and more changeable every year, the creation of new varieties with a high level of productivity, regardless of growing conditions, remains relevant up to now. The application of ecological plasticity and stability is widely used in such agricultural crops as winter bread wheat [22], spring bread and hard wheat [23,24], winter and spring barley [25−28], soybean [29], winter triticale [30], oats [31,32], corn [33], bean [34], etc. The stability of the breeding trait of sample is the deviation of empirical data in each environmental condition from the ecological plasticity of the breeding trait, that is, from average response to changing growing conditions.…”

When working with collection material, one of the main problems is the study of most of the samples in a cycle of three years and the annual partial renewal of the set under study. Therefore, only a part of the varieties can be directly compared with each other in terms of ecological stability, and the main grouping has to be carried out by comparing the behavior of samples with standard varieties under conditions of different years. Even well-studied varieties are not always suitable for such comparisons. When selecting the starting material for breeding, it is important not only to find forms with a high level of manifestation of quantitative traits, but also to minimize this level under unfavorable conditions for plant growth and development. The purpose of our research was to determine the stability and plasticity of collection samples of spring durum wheat of various ecological and geographical origins. Over the years of the research, the yield averaged 330.3 g/m 2 and varied from 434.3 g/m 2 (max) in 2015 to 188.5 g/m 2 (min) in 2018. This indicates that the genotype and contrast weather conditions of the years significantly affect the yield of collection samples of spring durum wheat. Stable and plastic collection samples of spring durum wheat were identified for yield: 193 THKNEE 8 (Mexico) (b i = 1.02, S 2 d i = 0.11), ARN AAZ-1.040 YRC-4M (Mexico) (b i = 1.35, S 2 d i = 0.12), SHAG 21 / CASCA (Mexico) (b i = 1.07, S 2 d i = 0.23), Hordeiforme 13-07 (Ukraine) (b i = 2.11, S 2 d i = 0.31). According to the results of our research, it was found that the highest grain weight per spike (1.90 g) was in the sample Voronezhskaya 11 (Russia), and the lowest value was in the sample Damsinskaya yantarnaya (Kazakhstan) (1.57 g). Among the plastic and stable collection samples by the grain weight per spike, the following samples were distinguished: DUN / MUSK 1 (b i = 3.45; S 2 d i = 0.07), SHAG 9 / BBUTO / 7 (b i = 1.61; S 2 d i = 0, 05), CASM 3 // SRN 3 ASAIH 15 (b i = 1.47; S 2 d i = 0.00), GREEN / SOMO (b i = 1.35; S 2 d i = 0.01) (Mexico), Lilek (Russia) (b i = 0.92, S 2 d i = 0.03), MAGH 72 FUTO ALG 86 (Mexico) (b i = 0.75, S 2 d i = 0.01), YAZI 13 (Mexico) (b i = 0.12, S 2 d i = 0.07).
