The practice of using collection material in the breeding of forage crops has long been relevant and one of the most effective methods for identifying genetic sources of economically valuable traits for breeding new highly productive varieties adapted to local environmental conditions. The purpose of the current study was to create and identify a new promising initial material for breeding crested wheatgrass for productivity in the North Caucasus region. Productivity improvement is the main concern of plant breeding, which all other specific directions are subordinate to. The study was carried out in 2017–2020. The objects of the study were 31 varieties of various ecological and geographical origin taken from the world collection of the All-Russian Research Institute of Plant Production named after N.I. Vavilov and 13 varieties developed by the Stavropol Research Institute of Agriculture, including the variety ‘Vikrav’, approved for use in the North Caucasus region as a hay and pasture grain crop in 1994. The trial was laid in fallow, in a single repetition, the accounting plot area was 1.75 m2 . According to the green and hay mass productivity, there have been identified 7 samples, they are ‘K-50974’ (from the Ukrainian village of Petrovsky), three wild-growing samples ‘K-52357’ (from Ukraine), ‘K-51330’ (from the Chelyabinsk region) and ‘K-52441’ (from Kazakhstan) and three samples ‘2/2–18’, ‘4/2–18’, ‘6/2–18’ (developed by the SNIISKh). According to seed productivity there have been distinguished 9 samples ‘K-50974’ (from the Ukrainian village of Petrovsky), four wild-growing samples ‘K-52357’, ‘K-51330’, ‘K-52441’, ‘K-51104’ and three samples ‘2/2–18’, ‘4/2–18’, ‘6/2–18’ (developed by the SNIISKh). According to the complex of the above described traits there have been identified 5 samples.

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.

The article examines the problems of open and latent ethnonational tension in Russian society, which in the conditions of aggravation of the social situation, may lead to the use of spontaneous methods of solving ethnonational conflicts, including those of a violent nature. A survey of 20 experts, who are qualified specialists in the sphere of ethno-extremism counteraction and ethno-national conflict localization, conducted by the author of the article, has shown that the majority of them have assessed both the current and forecasted situation in the sphere of ethnonational relations as “tense” for the next five to seven years. In their opinion, “ethnonational tension” is conditioned by a number of long-term factors that will influence the content and dynamics of ethnonational conflict in the Russian Federation: the desire of the USA for global dominance and the confrontational policy of NATO member states towards Russia; the antiRussian policy of the Ukrainian leadership, which is attempting to accuse Russia of “unleashing and waging a hybrid war against Ukraine” and actively pushing Western countries to strengthen confrontation with the Russian Federation; attempts by some states to bring territorial claims against Russia; intensification of the fight against embezzlement of budgetary funds, systemic corruption and ethno-extremist manifestations in the North Caucasus region; the ethnopolitical situation in the Republic of Crimea, characterized by manifestations of Ukrainian nationalism and militant Islamism. According to expert estimates, the highest degree of ethnonational tension is currently maintained in the Republic of Dagestan, the Republic of Ingushetia, the Kabardino-Balkarian Republic, the Karachayevo-Circassian Republic, the Republic of Crimea, the Republic of Bashkortostan and the Republic of Tatarstan. The results of research in the article testify to the necessity of constant study of the problem of ethnonational conflicts, research into the factors influencing the maintenance and dynamics of conflict potential, definition of Russian regions with an increased level of tension, development of recommendations to authorities on prevention and localization of ethnonational conflicts.
