Abstract The top cross method for assessing combining ability more economical and less laborious compared to diallel analysis, and also allows the breeder to obtain quite valuable information about the inbred material. In this research, the determination of the general (GCA) and specific (SCA) combining ability of barley (Hordeum vulgare L.) hybrids in two regions of Kazakhstan contrasting in soil and climatic conditions, the role of additive and non-additive genes in the determination of the traits under study has been revealed. It is concluded that the predominance of additive gene interactions in the control of the traits understudying the conditions of the Aral Sea region indicates the possibility of effective selection already in the F2 generation, and in the piedmont zone of the Almaty region, due to the high determination of these traits by dominant genes, it is necessary to differentiate the populations of hybrids, starting from the first generation and further selection shall be carried out in several cycles until the achievement of homozygosity of loci carrying dominant genes. Consequently, the genetic contribution of the additive and non-additive effects of genes to the determination and inheritance of the studied traits significantly depends on the conditions of growing the genotypes of spring barley. Of greatest practical interest are the varieties Rihane, WI2291/Roho/WI2269 from the International Center ICARDA and the variety-tester Odessa 100 (Odessa Selection and Genetic Institute, Ukraine) with high GCA and SCA effects, little dependent on growing conditions, which are recommended to be used as reliable donors in breeding programs.

The specifics of the soil and climatic conditions of the Aral sea region, Kazakhstan, primarily associated with salinization, various types of droughts, uneven distribution of precipitation during the growing season, and late spring frosts, make it necessary to create crop varieties with resistance to biotic and abiotic environmental factors. In this regard, the expansion of the area under crops of nontraditional salt-tolerant grain crops in the Kyzylorda region is one of the main directions of increasing the sustainability of agriculture in the region. Studies have shown that among the grain crops cultivated in the region, spring barley (Hordeum vulgare L.) is a reliable crop that can make the most of the region's bioclimatic resources to form sustainable yields. The purpose of this study is to create a new promising source material of barley based on a comprehensive study of collection material of various ecological and geographical origin by applying various methods of classical breeding. Based on a comprehensive assessment of the collection material of barley, a working collection of 250 varieties with agronomic resistance to environmental stress factors of the Aral Sea region was created. The selected samples are recommended for use in practical breeding in order to increase the adaptive potential of modern barley varieties.

The long-term dynamics of the main meteorological indicators is analyzed, their compliance with the requirements of growth and development of promising varieties of barley is established. Over the past 19 years, there has been an upward trend in temperature and precipitation over all months during the growing season. The significant effect of the sum of effective temperatures and hydrothermal coefficient on the yield formation of the studied barley varieties was established. The data obtained indicate the need to create varieties that are more resistant to high temperatures. Under changing meteorological conditions, important indicators of varieties are their resistance to stress conditions of growth (U2 – U1) and genetic flexibility of the variety (U1 + U2)/2. In our experiments established that the high stress resistance have varieties of Dina and Kotlasskiy; the increased genetic flexibility was highest in the varieties Kotlasskiy and Tausen'. The lowest coefficient of variation (V) was observed in Kotlasskiy variety, the most high — variety Vard. The highest stability index and index of the level of stability of the yield of the variety were noted in the Kotlasskiy variety.

The selection work has been carried out on the base of the Primorskiy branch of the Federal Center for Integrated Arctic Research of the Russian Academy of Sciences (FCIARctic) in 2005-2016, in a selection seven-field crop rotation. Various weather conditions contributed to a complete and comprehensive assessment of the selected sample. Data on agrometeorological research were provided by the Federal State Budgetary Institution “Northern UGMS” of the Hydrometсenter at the post of Kurtsevo. Assessment of breeding material was carried out by the main breeding valuable traits, taking into account the length of the growing season, resistance to lodging and grain yield according to the methodology of the State Commission for the Testing of Crops (1985).  Statistical processing of the experiment results were carried out using the genetic and selection software package AGROS version 2.07. A new variety of spring fodder barley “Kotlas” with increased adaptability for variable growing conditions was developed, it intended for cultivation in extreme climatic conditions of the Far North as an early ripening, productive, adaptive to unfavorable environmental factors to obtain concentrated feed for livestock and poultry. The variety is immune to net blotch of the Arkhangelsk population. The stability index (L) of the variety is 53. The new variety usage will increase the yield of spring barley, increase the economic efficiency of using the variety to 15%, the economic effect of introducing the variety per unit volume of production is 7.85 thousand rubles.

In small-grain cereals, grain yield is closely associated with grain number. Improved spikelet survival is an important trait for increasing grain yield. We investigated spikelet number, spikelet survival and yield-related traits under greenhouse conditions, and pot- and soil-grown field conditions. Thirty-two spring barley (Hordeum vulgare L.) accessions (14 two- and 18 six-rowed accessions) were manually dissected to determine spikelet/floret number on the main culm spike (SNS) at awn primordium (AP), tipping (TIP), heading and anther extrusion. We observed a significant difference between two- and six-rowed barley for SNS and spikelet survival at all stages and growing conditions. Both traits were highly genetically controlled, with repeatability and broad-sense heritability values of 0.74–0.93. The rate of spikelet survival from AP to harvest was higher in two- (~70%) than in six-rowed (~58%) barley. Spikelet abortion, starting immediately after AP, was negatively affected by increased SNS and the thermal time required to reach the AP stage. The largest proportion of spikelet reduction happened during the AP–TIP phase, which was the most critical period for spikelet survival. The duration between AP and the end of stem elongation correlated better with spikelet survival and yield-related characters than the estimated duration of stem elongation using leaf height measurements. Our observations indicate that the main spike plays an important role in single-plant grain yield. Extending the length of the critical AP–TIP phase is promising for improving yield through increased spikelet development and survival. The results also demonstrate that greenhouse conditions are appropriate for studying traits such as phase duration and spikelet survival in barley.

During growth, kernel of cereals can be provided with carbohydrate and nitrogen (N) from the translocation of pre-anthesis accumulated reserves stored either in the vegetative plant parts or from current assimilation during kernel development. This study was conducted to assess the effects of nitrogen level and cultivars on dry matter and N accumulation and mobilization during pre-anthesis and post-anthesis. Twenty two-rowed spring barley (Hordeum vulgare L.) cultivars were grown on a non-calcareous chernozem soil in four growing seasons (1995–1998) atNovi Sad (45°20'N, 15°51'E,86 m a.s.l.) at two nitrogen levels. Dry matter accumulation before anthesis ranged from less than 50% in unfavorable to 90% in favorable growing conditions. Dry matter translocation occurred in favorable growing conditions only. Pre-anthesis accumulated N represented 57–92% and 54–129% of total N at maturity at the low and high N levels, respectively. Translocated N represented 41–85% and 37–153% of grain N at the low and high N level, respectively. N losses occurred in favorable growing conditions when anthesis N exceeded 150 kg/ha. N accumulation during grain filling was in negative correlation with dry matter and N accumulation before anthesis. The N harvest index was 0.57–0.63 and 0.71–0.74 in unfavorable and favorable growing conditions, respectively. Selection of genotypes with a higher ability of pre-anthesis reserve utilization or genotypes with longer leaf area duration after anthesis may be two possible solutions in spring barley breeding for Mediterranean growing conditions.

Early Ripening

Barley (Hordeum vulgare L.) occupies more than 80% of the sown area of forage crops. Barley is widely cultivated in many areas with contrasting soil and climatic conditions; breeding varieties that are resistant to abiotic and biotic environmental stress factors is an important factor that would make it possible to obtain grain with the required nutritional and forage qualities. The creation of barley varieties is a promising area of breeding in the world. To create varieties, it is necessary to consider the main directions: early ripening and high yield. To create an early ripening, high-yielding variety and hybrid of spring barley with high technological qualities of grain, the leading role belongs to the scientifically grounded selection of the source material. The article presents the results of a 3-year collection samples’ study from the world collection of the All-Russian Institute of Plants’ Genetic Resources named after N.I. Vavilov (VIR).

Aim. The study’s purpose was to establish genetic patterns of waxy barley breeding on the basis of determination of genetic and breeding characteristics of accessions with different fractional composition of starch during 10/11-year cycles of the breeding process upon creation of waxy barley cultivars. Methods. Analysis of variance, calculus of variations, correlation analysis, genetic and breeding methods were used to investigate peculiarities of genotypes in topcross, diallel and pair-crossing designs. Results. The important scientific problem concerning establishment of genetic patterns of waxy spring barley breeding was solved. We determined morpho-biological features, variability, correlations and genetic peculiarities of inheritance, heritability, genetic variation and combining ability for quantitative traits of plants as well as for amylopectin content in starch of F1 hybrids derived from forms with different fractional composition of starch. As a result of establishing the patterns, the effectiveness of creation of valuable lines and waxy barley cultivar Shedevr with amylopectin starch was demonstrated. Conclusions. The morpho-biological, breeding and genetic peculiarities of plant traits with different fractional composition of starch were determined. On this basis, the genetic patterns of waxy barley breeding were established, and the first Ukrainian waxy barley cultivar Shedevr (with amylopectin starch) was created. Keywords: Hordeum vulgare L., accession, cultivar, amylopectin starch, genetic peculiarities.
