Relevance. Leek (Allium porrum L.) has been known as a cultivated plant since ancient times. It plays an important role in human nutrition. To increase the interest of the population, increase demand and consumption, as well as widespread and popularize this culture, it is urgent to create new promising varieties of leeks that meet modern requirements and have valuable economically useful traits. The creation of new highly productive varieties is associated with the search for sources of valuable biological and economic traits: productivity, early maturity, yield. The aim of the research was to study collection varieties of leeks, to identify the sources of the necessary valuable traits for their further use in breeding work. Materials and methods. The initial material was 73 samples of leeks of the European subspecies of various ecological and geographical origin from the collection of VIR. The studies were carried out at the collection site of the Krymsk EBS, VIR Branch (Krasnodar Territory, the city of Krymsk). Results. As a result of the study of phenological, biological, morphometric and economic characteristics, the foliage of the plant, the size of its and the false stem of the "leg", productivity and yield were determined. Formed groups of samples by ripeness and use. Comparative assessment of collection samples made it possible to identify the sources of productivity: the weight of the plant and the stem, its diameter and height, the yield of plants and the yield of marketable products. The isolated sources of valuable traits are recommended as a starting material for the selection of leeks.

Within the town of Norton, Massachusetts, close by the boundary between it and the city of Taunton, lies the beautiful little body of water known to this day by its Indian name of Winneconnet. This lake, fed by a system of streams from the north and west and draining southward through a complicated network of ponds, swamps, and streams into the Taunton River, seems to have been the center of a large area of Indian population in ancient times. Cultivation and other disturbances of the earth surfaces have demonstrated the existence of many sites of former Indian habitation, while numerous items in local tradition point to the fact that many Indians lived and died within the township. Hardly a garden plot that has not yielded its quota of stone implements to the collections of local “relic hunters” exists in this vicinity.

The article presents archaeologically fixed objects of wooden architecture of ancient times in Podil Kyiv, which scientists first interpreted as baths. Although there have been attempts in the national scientific literature to interpret the structures as baths (a monumental stone building of the XI century in the yard of the Kyiv Metropolitan, a wooden structure on the site 34 in Petrovsky's estate), first, these interpretations provoked debates. Secondly, they involved data only from Upper Kyiv - there was no case of identifying as a bath an archaeologically fixed object of wooden architecture in Podil. In the article, based on the analysis of available written, ethnographic and archaeological sources, the author proves the possibility of the existence of similar structures in the largest area of ​​Ancient Kyiv.The author addresses several issues regarding the mass development and planning structure of the ancient Russian hem. The first is the selection of more than 300 fixed objects of wooden architecture of this period, actually a bath. In doing so, it is proposed to use the technique of Khoroshov, which he proposed and implemented at the excavations of Ancient Novgorod. The second question concerns the revision and re-interpretation of the functional purpose of the investigated objects of ancient Russian architectural architecture recorded at the hem of Kyiv. Three buildings of the XII century are presented for consideration. (building No. 4, Obolonskaya St., 4, 1989, building No. 1, Pochayninska St., 27/44, 2003, building No. 8, Nizhniy Val St., 43, 1989), which the author proposes considered as baths that were part of the city planning structure. The author states that confirmation of the existence of bath-houses will allow to investigate the objects related to hygiene in the Old Rus and to expand not only the life of ancient Kyiv significantly. Also, it will be possible to make adjustments to the general reconstructions of the ordinary old-Russian manor and quarter.

Creation and introduction of new hybrids of sugar sorghum adaptive to arid conditions allow stabilizing and increasing the productivity of forage mass over the years, which is of current importance. The aim of the research was to clarify the scheme and methods of selection of the initial material, assess the level of true heterosis, quantitative traits of green mass yield and plant height in the best obtained hybrids of sugar sorghum. The research was carried out according to the methods of laboratory and field experiments. The scheme of the breeding process included nurseries of source material and breeding nurseries, as well as creation of self-pollinated and sterile lines, hybridization, assessment of samples for CMS, combining ability, and testing new hybrids by saturating crosses and topcross. According to this scheme, sterile lines ‘A-63’, ‘Knyazhna’, ‘Zersta 38A’ were created. By methods of multiple and individual selection with subsequent inbreeding from hybrid populations, fertile paternal forms ‘Stavropolskoe 36’, ‘Galia’ and ‘Larets’ were created. Also, obtained on their basis hybrids ‘Silosnoe 88’ (standard), ‘Alga’, ‘Kalaus’, ‘Yarik’ served as the object of research. On average for 2016–2019, the most significant plant height under the conditions of the “North-Caucasus Federal Agrarian Research Center” was found in late-ripening combinations ‘Yarik’ (301.4 cm) and ‘Kalaus’ (289.0 cm). The level of true heterosis of this trait was 41.7 % and 31.6 %, respectively. In the studied hybrids, the pollination period of the parental forms coincides, the heterosis of the thickness of the stems is observed. The significant leafiness of the plants is also found to be in the late-ripening forms (15.7–16.0 %). The maximum yield of green mass was obtained from hybrids ‘Yarik’ (102.0 t/ha) and ‘Kalaus’ (86.7 t/ha). The level of true heterosis of the studied trait in these combinations was 67.9 t/ha and 47.0 t/ha, respectively, or 66.5 % and 54.2 %. The combination of other genetic plasmas provided a lower level of true heterosis. The late-ripening hybrids ‘Yarik’ and ‘Kalaus’ have significantly higher sugar content in the juice of the stems (12.89–14.03 %) compared with the mid-ripening ‘Silosnoe 88’ (8.9 %) and the medium-late ‘Alga’ (11.14 %).

Over the last decades, the strategic profile of the discourse with which wars are narrated has been reinforced. This discourse has also varied in the light of a recent – and alleged – peace culture permeating Western societies. Whereas the war discourse in Russia during the Second Russian-Chechen War has been widely studied, this has not been the case of the rhetoric of the Chechen Islamist guerrillas. The aim of this paper is to contribute to bridging this gap in the academic literature on the North Caucasus, employing to this end a critical discourse analysis (CDA) of a selection of texts posted by the Kavkaz Center (KC) news agency. On the basis of this analysis, it can be concluded that one of the main discursive strategies revolved around the construction of an “us” embodying the Chechen victims of the initial aggression in a conflict provoked by the Russian “other”.

The article presents the results of a long-term study of the world collection of pears, which is one of the largest in the RIPB system. It is kept at the Maykop Experimental Station of the Federal Research Center of the All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov» branch and has 875 varieties, 248 species, forms and varieties, and is constantly updated with new samples. The collection includes wild species, as well as Russian and foreign varieties from Europe, America, Asia. The research was carried out in the soil and climatic conditions of the foothill zone of the North Caucasus in 2005–2015. The aim of the research is to study the dependence of biological traits and properties on the origin of samples and to isolate genotypes with the maximum expression of traits for use in breeding. In the research the methodological instructions of the All-Russian Research Institute of Breeding of Fruit Crops and the North Caucasus Center for the Breeding of Fruit, Berry, Flower and Ornamental Crops and Grapes have been used. The analysis of weather conditions has been carried out using meteorological data of the MES of the RIPB Branch. The regularities of the manifestation of signs and biological properties of the studied samples depending on their geographical origin have been established. The varieties that combine a fairly good quality of fruits and other, valuable characteristics have been identified: late flowering for protection from frost – Obilnaya Tuza, Uspenka; resistance to fungal diseases – Vodnik, Utrennyaya Svezhest; early maturity – Borup, Napoca and high regular yield – P. regelii x P. pyrifolia № 2 interspecific hybrid. As a result of many years of studying the world collection of pears the list of isolated genotypes of valuable traits has been added, the use of which contributes to a significant increase in the efficiency of breeding work.

The subject of this research is the toponyms Yessentuk, Yessentuchok, Yessentuki. The goal is ti determine their origin. The author leans on the data of explorations of the remains Golden Horde mausoleums of the XIV century, which were conducted in the late XX and early XXI centuries on the outskirts and in the area of the city of Yessentuki of Stavropol Krai. The article considers the previously revealed connection between mausoleums of the XIV century, Podkumok River Valley, and the Kabardian-Abazin tombstones of the XVIII century located here. It is worth noting that at the time of construction of the Yessentuki reduit at the end of the XVIII century, the general population of the area were Kabardians and Abazins. The application of comprehensive approach alongside various methods of historical and philological sciences allowed determining the origins of the toponyms Yessentuk, Yessentuchok, Yessentuki, as well as carrying out further reconstruction of the history of the Central Fore-Caucasus of pre-Russian and Russian eras. The conclusion is made that the name Yessentuk (in later versions – Yessentuchok and Yessentuki) stems from the Kabardian word combination Yesen tlygu – the edge, area, or border) of Yesen. The personal name Yesen is of Turkic-Mongolian origin and can be occasionally seen in the anthroponymy of the Adyghe and neighboring peoples. The obtained results can be used in studying history of the North Caucasus, toponymic research, museology, creation of science education films.

This article has been retracted. Aim. To evaluate the experience of participating in the creation of a national registry of hematopoietic stem cells donors.Methods. Potential hematopoietic stem cells donor filled out a questionnaire, after the examination, he was assigned an individual donor code (bar code). The results of typing and questionnaires are placed on the registry of potential hematopoietic stem cells donors. Maintenance of HLA-typed potential hematopoietic stem cells donors registry and the selection of compatible «donor-recipient» pairs in RMSPC «Rosplazma» were performed using a specialized program «Prometheus» (Steiner Ltd., Czech Republic).Results. 484 donors, who were indigenous peoples of Stavropol and Stavropol Krai, as well as representatives of the North Caucasus small nations of different nationalities, were included into the registry for the period from 08.20.2013 to 20.06.2014. Age ranged from 19 to 42 years. As of 31.10.2015, 31 491 potential hematopoietic stem cells donors (54% - female, 46% - male) were included into the registry, 28 509 donors were typed: 24 310 for HLA - A, B, C, and DRB1 loci; 2305 for HLA - A, B, C, DRB1, and DQB1 loci; 1894 for HLA - A, B, and DRB1 loci. The registry has the highest number of A-B-DRB1 typed donors among Russian registries. New HLA-alleles in the Russian populations were revealed in 57 cases for 28 509 typing (1:500).Conclusion. There is a clear need to enhance cooperation of RMSPC «Rosplazma» with all regions of Russia and create unified national registry of hematopoietic stem cells donors with its inclusion in international databases.

Цель публикации – всестороннее изучение хода борьбы за Краснодар между Красной Армией и вермахтом в начале 1943 г., в результате которой 12 февраля административный центр Кубани был освобожден от немецкой оккупации. Изучены различные аспекты сражения, развернувшегося за город во время наступления советских войск на территории Краснодарского края в начале 1943 г. Использованы данные, приведенные в работах советских историков. Основными источниками для исследования стали советские и немецкие оперативные документы и воспоминания участников битвы за Кавказ. Проанализированы планирование и подготовка операции на краснодарском направлении, дана характеристика советским и немецко-румынским силам, выделены основные этапы боев за Краснодар. Раскрыты трудности, с которыми столкнулись советские войска в ходе первой крупномасштабной наступательной операции на Северном Кавказе. Определены мотивы, которыми руководствовалось советское и германское военное командование в ходе борьбы за Краснодар. The offensive operation of the Red Army in the North Caucasus in 1943 was one of the turning points of the Great Patriotic War of 1941–1945. During this battle, on February 12, Krasnodar, the administrative center of the Kuban and an important transport hub in southern Russia, was liberated from German occupation. According to the tradition established in historiography, the struggle for this city is associated with the events of the first half of February 1943, when the fighting took place within the city and on the outskirts of Krasnodar. The aim of the publication was a comprehensive study of the course of the struggle for Krasnodar between the Red Army and the Wehrmacht in early 1943. The article used the data presented in the works of A.S. Zavyalov, A.S. Kalyadin, A.A. Grechko, V. Tike, S.V. Janusz, R. Forzik. The main sources for the study were Soviet and German operational documents of the Central Archive of the Ministry of Defence of the Russian Federation and the National Archives and Documentation Administration of the United States. Along with them, the memories of the participants in the hostilities near Krasnodar were used. In the course of the study, the author relied on historical-comparative and historical-genetic methods. The planning and preparation of the operation in the Krasnodar direction are analyzed, the Soviet and German-Romanian forces are characterized, the main stages of the battles for Krasnodar are identified, the operations of the Red Army combat units in the course of the struggle for the city are studied and systematically described. Particular emphasis is placed on studying the difficulties that the Soviet troops encountered during the first large-scale offensive operation in the North Caucasus. Considerable attention is paid to determining the motives that guided the Soviet and German military commanders during the struggle for Krasnodar. The Red Army failed to implement the full-scale offensive plans near Krasnodar. Victories near Stalingrad and the Middle Don allowed counting on the defeat of the troops of Germany and its allies in the North Caucasus. But the Soviet troops did not have enough strength and time to implement this plan. The command of the German Seventeenth Army managed to escape encirclement and divert its forces to the line prepared for defense—the Kuban bridgehead. Nevertheless, the winter campaign of 1943 ended with a retreat, which means the defeat of the Wehrmacht in the Caucasus and the entire south of Russia, the beginning of a turning point in the struggle on the Soviet-German front.
