“…In the Kyzylorda region, the allelic effects of genes exceeded the no allelic ones in the length of the growing season, while in the piedmont zone of the Almaty region, both additive and non-additive gene interactions equally controlled the said trait. Although, when determining the peculiarities of the combinational ability of spinous and spineless cultivars of spring barley and their parent forms in F 1 , strong SCA effects resulted in thousand-grain weight (Kompanets et al, 2017). Therefore, this feature depends not only on the influence of the environment but also on the barley cultivars.…”

For assessing the combining ability, the top cross method proved more economical and less laborious compared with the diallel analysis. It also allows the breeder to obtain valuable information about the inbred lines and their hybrids for various traits. In the existing research, determining the combining ability of barley (Hordeum vulgare L.) hybrids took place in two regions of Kazakhstan with contrasting soil and climatic conditions. The additive and non-additive genes played a vital role in determining almost all the traits in barley. Analysis of variance showed varying significance among the barley cultivars and their hybrids and testing sites for the majority of the traits. Analysis of variance also revealed significant differences in general combining ability (GCA) and specific combining ability (SCA) among the parental cultivars and their hybrids in barley. The predominance of additive gene interactions in controlling the traits under environmental conditions of the Aral Sea region indicates the possibility of effective selection already in the F2 generation. However, in the piedmont zone of the Almaty region, the dominant genes managed the traits, and thus, necessary to differentiate the hybrid populations, starting from the first generation, until further selection from several cycles achieved the homozygosis of loci carrying dominant genes. Barley cultivars, Rihane, WI2291/Roho/WI2269 (ICARDA), and the tester, Odessa-100 (Odessa Selection and Genetic Institute, Ukraine), showed greater practical interest and therefore, recommended for use as reliable donors in future breeding programs.

“…Тритикале -штучно створений біологічний вид, який не має природнього центру походження і тривалого процесу еволюції. Тому необхідною умовою для успішної селекційної роботи є постійне отримання нового вихідного матеріалу із залученням широкого різноманіття наявних форм і віддалених видів, зокрема, пшениці та жита з найкращими характеристиками за господарсько-цінними ознаками і властивостями [1,2].…”

Different weather conditions provide unequal growth and development of plants, in addition, biotypes react differently to changes in external environmental factors. Scientists from Ukraine and other countries analyze varieties and samples of spring barley for the purpose of determine donors of useful traits in different soil and climatic conditions. For the purpose of combine a number of useful traits in one genotype, hybridization between geographically distant biotypes is used. Uman National University of Horticulture has a collection of spring barley samples by different geographic origin. The analyze of breeding material by biometric traits, which will allow us to determine the level of manifestation of each of them in different conditions of 2018–2020 and to determine the donors of useful traits for the further breeding process, was carried out. The weather conditions of the years of research were very different. 2018 was the most unfavorable year for early spring crops. The reason for this was the presence of snow cover until the end of March. After that were strong heat and lack of precipitation. 2019 and 2020 were more favorable for spring barley due to the long cool spring. In addition, in 2020, May and June characterized by increased rainfall. The average plant height of the studied biotypes ranged from 50 to 64 cm. Most samples had the lowest plant height 40–57 cm in 2018, and the highest – in 2020 – from 54 to 88 cm. The average spike length of the analyzed samples was 5.9–8.1 cm. There was not dependence between conditions of the research year and spike length. The number of spikelets per spike was naturally determined by the research conditions. The lowest indicators were observed in 2018 — from 7.0 to 12.0 units, while in 2019 — 16.6–23.9 units, and in 2020 — 20.2–27.7 units. The variation of plant height of the analyzed samples was medium and significant with coefficients from 13.7 to 32.6 %. There was a slight, medium and significant variation of the length of the ear (V = 2.9–23.6 %). The index of number of spikelets per spike most varied — the coefficients of variation were 32.6–55.5 %.

“…The manifestation of any quantitative trait depends on the combined action of a set of genes and the environment [10,11], which determine the genotypeenvironmental interaction -a powerful factor in increasing productivity [12]. At the same time, it should be borne in mind that an effective method for creating adaptive, yielding varieties is diallel analysis [13][14][15][16]. Due to the fact that selection in early generations is ineffective, which is associated with the effects of dominance, heterosis epistasis [17], and overdominance (according to many traits), which disappear with repeated replanting, due to a decrease in non-additive variances, therefore, the selection of productive genotypes is facilitated in later generations [12,18].…”

The selection of parental pairs is carried out considering their genealogical trees and the dynamics of the lim factors of the environment, in the creation area, with further hybridization, and subsequent multiple re-sowing of the population. The Kazakhstanskaya rannespelaya variety was created by selection from the F5 hybrid combination of Novosibirskaya 67 × Omskaya 9, the Interdepartmental program DIAS. The breeding record of Novosibirskaya 67 consists of 9 and Omskaya 9 – of 37 varieties, of which 19 are of winter origin. The inheritance of ear productivity, in both varieties, followed the type of complementary epistasis, with incomplete dominance and overdominance, with a large proportion, of recessive genes. In conditions of the Northern Trans-Urals, an early-ripening, yielding line was selected in F5 - Lutescens 1227-8-79, which became the ancestor of the Kazakhstanskaya rannespelaya variety. The variety has successfully passed the State variety testing and is registered in the Qostanay, North Kazakhstan and Kokchetav regions of Kazakhstan, and in the Chelyabinsk region of the Russian Federation, according to the grain quality it is included in the list of strong varieties. In the north of Kazakhstan, Kazakhstanskaya rannespelaya is cultivated on large areas. This variety, as a genetic source, has a good variety-forming ability. With its participation, 6 varieties were created in the Research Institute of the Northern Trans-Urals. Of these, Tyumenskaya 29 and Grenada are registered in 9 and 10 zones of the Russian Federation. It is used in the breeding programs of the Republic of Kazakhstan.
