“…N.I. Vasko (2018) notes that the study of ear length is essential for breeding improvement, and selection based on this trait allows the creation of the desired length in combination with a greater number of ears, grains, and larger grain size. Research by several scientists has provided numerous facts about the emergence of new forms in ear length and other characteristics not present in the parental plants, which can be attributed to transgression.…”

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.

“…Meanwhile, N.I. Vasko (2018), studying barley, notes that selecting for plant height is promising, although its impact on productivity is indirect. However, in the breeding process, the level of expression of this trait must be considered, as a reduction in plant height may lead to a loss of yield due to a decrease in vegetative mass and nutrient assimilation.…”

One of the most effective methods for increasing yield and resistance to abiotic and biotic factors in the environment is genetic selection and improvement of varieties. Solving these tasks is possible using positive transgressions, which are of great practical importance at this stage of selection. The aim of the research was to determine the coefficient of heritability in the broad sense (H2 ) and the degree and frequency of transgressions for productivity traits in second-generation hybrids of naked oat, created by crossing based on the eco-geographical principle and selection of economically valuable biotypes for further breeding work. During 2021, research was conducted on 15 intervarietal hybrids. F2 and parental components were analysed for traits such as plant height, spike length, number of spikelets per spike, number of grains per spikelet, and grain weight per spikelet. Field research methods (phenological observations), laboratory methods (structural analysis of the material under study), and mathematical-statistical methods (objective evaluation of the experimental data obtained) were used. A prominent level of the coefficient was observed for the trait “grain weight per spikelet”, ranging from 0.66 to 0.88 in hybrid populations OM 11-3007/Abel, OM 2803/Abel, Percy Can/Inermis, Percy Can/Abel. The analysis of the second-generation F2 intervarietal hybrids of naked oat allowed the identification of transgressions for all the studied traits. The highest number of positive transgressions was found for the following productivity traits: spike length (Tf 31.82 – 59.09%, Td 7.53 – 15.49%); number of spikelets per spike (Tf 27.30 – 54.50%, Td 8.85 – 26.49%); number of grains per spikelet (Tf 45.50 – 77.27%, Td 16.63 – 27.62%); and grain weight per spikelet (Tf 63.64 – 81.80%, Td 18.12 – 25.36%). The selection-genetic analysis of studying the nature of heritability, frequency, and degree of transgressive variation in spikelet productivity traits of F2 naked oat hybrids allowed the identification of a considerable number of transgressive forms, in which productivity elements vary widely, indicating successful selection work in creating promising high-yielding breeding material
