Winter barley is one of the early ripening grain crops. It is the early ripeness combined with high productivity, lesser needs in good growing conditions that determines the great national economic importance of this culture. To increase and stabilize gross yields of winter barley, it is necessary to develop new varieties adapted to the negative environmental factors. The purpose of the study is to identify promising breeding material for winter barley to grow varieties with high agroecological stability and adaptability to local soil and climatic conditions. The studies were conducted in the FSBSI “Agricultural Research Center “Donskoy” in 2015–2018. The objects of research were the commercial varieties “Timofey”, “Yeryoma”, “Vivat”, the new winter barley varieties “Foks 1”, “Marusya”, as well as the promising breeding lines. The weather conditions of 2017 were more favorable compared with those of 2016 and 2018, which allowed producing higher yields. All the studied winter barley varieties, even in the wet conditions of 2017, showed a high resistance to lodging (4–5 points by a 5-point scale). In the spring and summer months of 2018, there was a significant increase in temperature in comparison with that of 2017. In June there were some days with dry wind, and therefore the air humidity dropped to 38% (23% lower than the multiyear average). The analysis of the yield structure showed that in 2016 the winter barley varieties showed higher values of the traits “number of kernels per ear” and “1000-kernel weight”, and “number of productive stems per 1 m2” in 2017. According to a comprehensive estimation, there have been identified the promising winter barley varieties “Marusya”, “Parallelum 1960” and “Parallelum 1962”, which significantly exceeded the standard variety “Timofey” in terms of productivity, and showed complex resistance to leaf diseases. In 2016, the variety “Marusya” was sent to be studied in the State Variety Network of RF through the North Caucasus region.

Currently, more than 70 wheat rust resistance genes are known, but few of them are effective. The purpose of this work is to screen lines of Lr gene carriers for resistance to leaf rust under conditions of the North Caucasus region. Investigations were carried out in 2016-2018 at the infectious site of VNIIBZR. Research material was 49 near isogenic lines of winter wheat cultivar Thatcher. Infectious material was the combined populations of P. triticina, obtained as a result of route surveys of industrial and breeding crops of winter wheat in the areas of the Krasnodar, Stavropol Territories and the Rostov Region, conducted in 2016-2018. According to the assessment, the genes are ranked as follows: - highly efficient genes (plants with no signs of damage): Lr9, Lr42, Lr43 + 24 and Lr50; effective (1R-5R) Lr genes: 19, 24, 29, 36, 37, 38, 45, 47; moderately effective (10MR-20MR) Lr genes: 17, 18, 21, 22a, 28, 32, 41, 52. The remaining Lr-lines were susceptible to P. triticina (25 MR - 90S) to varying degrees. Highly efficient and effective genes Lr9, Lr19, Lr24, Lr29, Lr38, Lr42, Lr43 + 24, Lr47 and Lr50 showed resistance in the seedling phase and can be recommended for inclusion in breeding programs to protect wheat from leaf rust in different phases of plant ontogenesis in the North Caucasus region.

The article is devoted to the consideration of the worldview positions of famous educators of the past century regarding the state of school education among Muslims of the North Caucasus region. It is proved that the enlighteners advocated the creation of a new type of national non-class school and the construction of the didactic foundations of the educational process in it. The novelty of the work is that, based on the analysis of the views of the advanced intelligentsia of the region, aimed at understanding the current socio-cultural situation, an attempt was made to scientifically understand the problems and prospects for the development of the Muslim educational system of the past from the point of view of the modern scientific paradigm. The practical significance of the publication lies in expanding the understanding of the system of Mohammedan education in the context of its historical heritage, which will help to comprehend modern problems associated with the reform of general and vocational education in the national Muslim republics.

The aim of the study was to monitor the virulence of Puccinia graminis Pers. f. sp. tritici in the North Caucasus.  The objectives of the study were to collect P. graminis infectious material from sown winter wheat varieties and evaluate the long-term dynamics of the pathogen virulence in the North Caucasus region in 2014-2019. As a result, an analysis of the virulence of the stem rust pathogen population of wheat collected in Krasnodar, Stavropol Territories, and Rostov Region was carried out. 81 mono-empty mushroom isolates were isolated and differentiated.  The genes Sr5, Sr31, Sr38 were characterized by high efficiency.  On the lines with the genes Sr7b, Sr8b, Sr9f, Sr9g, Sr10, Sr11, Sr12, Sr13, Sr14, Sr21, Sr22, Sr23, Sr26, Sr29, Sr32, Sr33, S35, Sr37, SrDp2, SrWLD, a variation in the virulence frequencies of P. graminis was observed.  Significant changes (in the direction of increasing occurrence) in the North Caucasian population 2014-2019  the pathogen was noted in the frequency of clones virulent to wheat lines with resistance genes Sr11, Sr21, Sr22, Sr26, Sr32, Sr33. A decrease in the frequency of clones virulent to Sr8b, Sr9g, Sr10, Sr12, Sr14, Sr35. At approximately the same level, the occurrence of clones virulent to the genes Sr6, Sr7a, Sr8а, Sr9a, Sr9b, Sr9d, Sr9e, Sr13, Sr15, Sr16, Sr17, Sr19, Sr20, Sr24, Sr25, Sr27, Sr30, Sr36, Sr39, Sr40, Sr44, SrGt, SrTmp. Effective genes that have shown their resistance to P. graminis in the seedling phase are proposed for use in breeding in southern Russia to create new varieties of wheat.

Relevance. The success of breeding work is largely determined by the source material, the search and creation of which for target breeding begins with the collection and study of collectible samples for the alignment of morphological features; for the precocity and amity of maturation; for the keeping quality and transportability of bulbs; for the quality of vegetable products (high content of biologically active substances and antioxidants); for resistance to biotic and abiotic stressors of a specific growing zone.Materials and methods. On the basis of the North Caucasus branch FSBSI FSVC, 90 samples of spring onions from 26 countries of the world were evaluated in the number nursery for the period from 2017 to 2019, 71 of them were varieties and 19 were F1 hybrids. In a hybrid nursery, 25 hybrid combinations obtained from FSBSI FSVC (VNIISSOK) were evaluated. The laying and placement of experiments, agricultural techniques of cultivation, accounting and evaluation of economically valuable traits, biochemical analyses were carried out according to generally accepted methods. The standards are the new Primo and Ampex varieties of the selection of the FSBSI FSVC and the Italian F1 hybrid Ranko, which were placed every 10 collection samples.Results.According to the results of the assessment, among the studied F1 varieties and hybrids, sources of economically valuable traits such as yield (20-27 t/ha), precocity (80-90 days), preservation (more than 85%) when laid for long-term storage up to 7 months, purple, white and pink color of bulbs, as well as sources of long-shaped bulbs were identified. The greatest interest for breeding for yield is represented by 9 promising varieties and 9 F1 hybrids of onions of various origins, as well as 4 hybrid combinations that were distinguished by high yields, the yield of marketable products and the mass of marketable bulbs. These samples are recommended for use in the breeding process as sources for the creation of new varieties and hybrids with high yields for the agro-climatic conditions of the foothill zone of the North Caucasus.r breeding
