Grain production stabilization is one of the main criteria for the development of agriculture in Russia. In this regard, in modern breeding, when developing varieties, considerable attention must be paid to their adaptability, i.e. parameters that ensure stable productivity in various growing conditions. The purpose of the current study was to estimate the spring barley samples according to the trait ‘yield’ for adaptability to the arid conditions of the Stavropol Territory and their further use in breeding work. The material for the study were 86 spring barley samples. In order to determine the stability, there was used a variance coefficient (V%) according to the method of B.A. Dospekhov (2014). The ecological adaptability (bi) and the environment index (Ij) were determined according to the method of S.A. Eberhart and W.A. Russell (1966) as presented by V.Z. Pakudin (1984). Homeostaticity (Hom) was assessed according to the method of V.V. Hangildin (1981). Stress resistance was determined according to the equations of A.A. Rosielle and J. Hamblin as presented by A.A. Goncharenko (2005). There were identified the highly productive samples ‘Mamlyuk’ (389 g/m2) and ‘Stirling’ (378 g/m2), possessing high responsiveness to improving environmental conditions (bi = 1.44–1.21), variability (V = 58.9–51,2%) and low stress resistance (Ymin – Ymax = -538–488). Such genotypes are capable of forming high yields in favorable conditions and may be of interest for breeding high-intensity varieties. The samples weakly responsive to changes in growing conditions were distinguished by high stability and homeostaticity according to the trait ‘yield’, namely ‘Nutans 74840’ (Hom = 2.88; V = 38.4%) and ‘Veles’ (Hom = 2.56; V = 38.5%), as well as the adaptable variety ‘Getman’ (Hom = 2.89; V = 40.6%). These samples are the most adaptive to the arid conditions of the Stavropol Territory and regions with similar cultivation conditions. They are recommended for use in breeding work.

Spring barley breeding in the Rostov region is aimed at developing early maturing, drought-resistant, high-yielding varieties with good technological qualities of grain. Productivity is mainly affected by the economic and biological parameters of the variety and the environmental conditions in the growing area. The purpose of the research is to conduct a comparative assessment of spring barley varieties by indicative parameters of ecological plasticity and yield stability to changes in environmental conditions. In 2018-2020, for a targeted study of this impact, trials with 18 spring barley varieties of Russian and foreign breeding to estimate their ecological adaptability and stability were carried out. Square of the plot – 10 m2; experiment was replicated thrice. Soil – chernozem ordinary with humus content in the arable layer at the level of 3.0–3.5%, pH = 7.0–7.1. Phosphorus content – 15–20 mg/kg of soil, exchangeable potassium – 300–500 mg/kg. The estimation of the effect on the ecological plasticity and stability of varieties was carried out according to the method of S.A. Eberhart, W.A. Rassel edited by V.A. Zykin (2005). Indicators of homeostaticity and breeding value were calculated according to the V.V. Khangildin and N.A. Litvinenko method (1981). Over the years of research, the productivity formation was mainly influenced by the factors ‘variety’ (66.1%) and ‘year’ (31.7%). The environmental conditions index showed that more favorable growing conditions were in 2020 (Ij = +0.23); in 2018, on the contrary, they were relatively unfavorable (Ij = –0.19). As a result of the three-year analysis, the highest productivity was identified in the varieties ‘Format’ (4,9 t/ha), ‘Fedos’ (4,8 t/ha) and ‘Gris’ (4,8 t/ha). In general, according to the complex of adaptivity parameters, ‘Format’ variety was distinguished. It has high indicators of breeding value (Sc = 4.6), stress resistance (Ymin-Ymax = –0.3), high stable productivity, as well as a high homeostatic index (Hom = 531) and a low coefficient of variation (V = 3.1%).

SUMMARYIncreased harvest index (HI) has been one of the principal factors contributing to genetic yield improvements in spring barley (Hordeum vulgare L.), oat (Avena sativa L.) and wheat (Triticum aestivum L.) cultivars. Although high HI demonstrates high-yielding ability when cultivars are compared, it can also indicate challenges to yield formation when comparisons are made across differing growing conditions. The present study was designed to investigate variation in HI among modern cereal cultivars relative to that brought about by a northern environment, to assess whether HI still explains the majority of the differences in grain yield when only modern cereal cultivars are compared, and to monitor key traits contributing to HI. Stability of HI was also investigated with reference to the role of tillers. Twelve experiments (3 years, two locations, two nitrogen fertilizer regimes) were carried out in southern Finland to evaluate 12 two-row spring barley, 10 six-row barley, 10 oat and 11 wheat cultivars. In addition to HI, days to heading and maturity, length of grain filling period, grain yield, test weight and 13 traits characterizing plant stand structure were measured and analysed with principal component analysis (PCA) to detect traits associated with HI and those contributing to stability of HI. Although only modern cereals were studied, differences among cultivars were significant both in mean HI and stability of HI, and HI was associated with short plant stature in all modern cereal species. Also, single grain weight was associated with HI in all species. Differences between, but not within, species in HI were partly attributable to differences in tiller performance. Grain yield was associated closely with HI except in two-row barley. It may be possible to further increase HI of wheat, as it still was relatively low. High HI did, however, not indicate the degree of success in yield determination when environments are compared.
