“…В настоящее время наличие у новых сортов только высокой потенциальной урожайности недостаточно: она должна оптимально сочетаться со стабильностью (Gudzenko et al, 2017;Nikolaev et al, 2019). Данное свойство возможно оценивать одним из многочисленных современных методов, а именно изменчивостью индекса стабильности (ИС) (Hangildin, Asfondiyarova, 1977).…”

Background. The barley collection at the N.I. Vavilov AllRussian Institute of Plant Genetic Resources (VIR), being the main source of source material for breeding, is insufficiently studied under conditions of extreme continental climate. The purpose of the research was to assess the adaptability of barley cultivars held by VIR to extreme continentality.Material and methods. The research targets were 24 barley cultivars representing various breeding centers and tolerance regions of Russia. The cultivar ‘Omsky 91’ developed at Omsk Agrarian Scientific Center was used as the reference.Results and discussion. According to the genetic profiles for alleles of hordein-coding loci, provided by the Vavilov Institute of General Genetics, more than 70% of the studied barley cultivars (‘Chelyabinsky 99’, ‘Priazovsky 9’, ‘Zadel’, ‘Sokol’, ‘Zernogradsky 584’, ‘Zadonsky 8’, ‘Khadzhibey’, ‘Beatrice’, ‘Knyazhich’, ‘Zevs’, ‘Kazak’) were linear in their hordein-coding loci. The homeostasis of the cultivars, their stability indices and plasticity levels were calculated. Their intensity measures and selection differentials were determined.Conclusion. The adaptability assessment based on the sum of ranks (calculated using the abovementioned adaptability parameters) showed that the monomorphic cultivars ‘Priazovsky 9’ and ‘Chelyabinsky 99’ as well as cv. ‘Severyanin’ (not listed in the State Register for Selection Achievements) were most adapted to extreme continental climate conditions (sums of ranks ranged from 8 to 29). The adaptability of the identified cultivars was confirmed by high-yielding hybrid populations produced from crossing the selected adaptable cv. ‘Chelyabinsky 99’ with cvs. ‘Omsky 91’ and ‘Omsky 95’ released by Omsk Agrarian Scientific Center. The obtained lines demonstrated higher yields than both the mean yield of the parent cultivars (+1.20 t/ha) and the yield of the best parent cultivar (+0.76 t/ha).

Spring oats are one of the most important crops among grain crops, and they are well adapted to the conditions of Western Siberia. To realize qualitative and quantitative characteristics of yield and increase productivity, new varieties should be characterized by responsiveness to changing environmental factors (adaptability) with sufficient potential productivity and ability to realize it even in the stressful conditions of this region. The aim of the research was to determine adaptive properties of spring oat cultivars developed in Omsk Agrarian Scientific Center. The experiments were carried out on the experimental fields of the Omsk Agrarian Scientific Center, located in the southern forest-steppe zone of Western Siberia, in 2011-2019. The st following adaptability parameters were calculated: stress tolerance Kst (according to A.V. Bykov), homeostaticity Hom (V.V. Khangildin), breeding value of cultivar Sc (according to N.A. Orlyansky), genotypic effect Ɛi (B.P. Guriev), coefficient of variation V and coefficient of uniformity B (B.A. Dospekhov), resilience of stability index У (R.A. Udachin and P.A. Golovchenko), rate of reaction of varieties to the environmental conditions Re (V.V. Novokhatin), equivalent plasticity Wi (C. Wricke). Using a significant number of indicators to obtain a final assessment of adaptability, a ranking of cultivars was carried out. Among hulled oat cultivars, Orion (control), Irtysh 13 and Irtysh 21 had increased adaptability (the sum of the ranks was 23, 35 and 36, respectively). In naked oat cultivars, Progress was more stable (the sum of the ranks was 79). These cultivars are recommended for cultivation in conditions of the southern forest-steppe of Western Siberia.

Spring barley is a key grain-fodder and fodder crop, which forms an increased yield compared to other grain-fodder crops due to early maturity and drought resistance. Taking into account climatic factors and production demands, breeding for increased productivity and adaptability to local natural and climatic factors, resistance to biotic and abiotic stresses is relevant today. The purpose of the research was to assess the fitness of spring barley varieties (Hordeum sativum L.) bred by the Omsk Agrarian Scientific Center for the conditions of climate transition from continental to sharply continental in Western Siberia. The object of the research: eleven varieties of spring barley, which belong to the multi-row hulled (standard ‘Omskiy 99’), two-row hulled (standard ‘Omskiy 95’), multi-row hulless or “naked” (standard ‘Omskiy golozerny 2’) and two-row hulless (standard ‘Omskiy golozerny 1’). The studies were carried out in the zone of the southern forest-steppe of Western Siberia from 2011 to 2019. The coefficient of linear regression and the stability of the reaction of the yield of varieties were calculated. Under the conditions of the continental and sharply continental climate of Western Siberia, the average yield of spring barley for the period of research was 4.03 t/ha (Lim. = 2.23–5.63 t/ha). The intensive group includes varieties ‘Omskiy golozerny 4’, ‘Sibirskiy Avangard’ and ‘Sasha’ (regression coefficient more than 1). Increased stability of the yield was noted in the varieties ‘Omskiy golozerny 2’, ‘Omskiy golozerny 1’, ‘Sasha’, ‘Omskiy 90’, ‘Omskiy 96’, ‘Omskiy 100’ (stability variance less than 0.29). Varieties ‘Omskiy 96’ and ‘Omskiy 100’ are characterized by full compliance of the formed yield with those agrotechnical conditions in which they are grown at a fairly stable level of productivity formation. The highest average yield over the years of the study was formed by the varieties ‘Sasha’ (4.70 t/ha) with values of plasticity (regression coefficient is equal 1.1) and stability (stability variance is equal 0.18), ‘Omskiy 100’ (4.89 t/ha; 1.02; 0.11, respectively). We recommend them for cultivation in the region.
