The research was conducted in 2014-2017 in the department of selection of fodder, grain ears, and industrial crops in the fields of scientific crop rotation of the Institute of Fodder and Agriculture of Podillya NAAS of Ukraine. A collection of 114 hexaploid specimens of different ecological and geographical origins was used as research material. Six varieties of winter triticale of different ecological and geographical origin and the manifestation of valuable economic features were used in crosses according to the scheme of full diallel analysis: Polovetske (UA0602494), Amos (UA0602627) originating from Ukraine; Kapryz (UA0601781), Tsekad 90 (UA0602066) - Russia; Dubrava (UA0602222) - Belarus and Pawo (UA0602555) - Poland. Only the best plants, which did not lag in growth and were normally developed, were selected for hybridization. The obtained generation F0 was sown in 2016, and generation F1 – 2017 manually in an experimental field with the same depth, which provides plants with the same area of nutrition. After full maturation, the plants were also collected manually in sheaves, structural analysis was performed on the main indicators of productivity. The frequency and degree of manifestation of positive transgressions in hybrids of the second generation (F2) of winter triticale were evaluated based on productivity: productive bushiness, number and weight of ear grains and grain weight from the plant. The best hybrids by degree and frequency of manifestation of positive transgression are selected. The degree of transgressions in productive bushiness averaged 65.3%, frequency - 43%; number of grains in the main ear - 7.4%, frequency - 15.3%; weight of grain in the ear - 13.8% at a frequency of 27, 7%; weight of grain from the plant - 91.5% with a transgression frequency of 52.7%. The best hybrid combinations of winter triticale on the basis of "productive bushiness" - Polovtsian / Caprice and Dubrava / Polovtsian (Tc = 100%), the maximum frequency of transgressions on this basis - hybrids Polovtsian / Caprice / Pawos and Pawo are selected and offered for use in the selection process. TC = 60); "Number of grains from the ear" - the maximum degree of transgressions was found in the hybrid Pawo / Polovtsian (Tc = 18.1%), the maximum frequency - in the hybrid Caprich / Pawo (Tch = 40); "Ear grain mass" - Pawo / Amos (Tc = 37.0%), the highest frequency of transgressions - in hybrids Amos / Dubrava and Kaprikh / Pawo (Tch = 50); "Grain weight from the plant" - Polovtsian / Amos (Tc = 37.0%), the frequency of transgressions - hybrids Polovtsian / Amos and Polovtsian / Caprice (Tc = 85%).

The article presents the results of a five-year study of the yield of the Melba apple variety on dwarf, semi-dwarf and medium-sized rootstocks selected by the North Caucasus Federal Scientific Center for Horticulture, Viticulture, and Winemaking (SKFNCSVV). The aim of the research is to study the influence of rootstocks of different growth strengths on the productivity potential of the Melba apple variety in the natural and climatic conditions of the Astrakhan region. The research revealed the influence of the rootstock genotype on the main productivity indicators: perishability, yield, frequency of fruiting, stability of productivity, marketable qualities of fruits. The early fruitfulness of the variety was most affected by the dwarf subspecies SK 3, SK 7 and semi-dwarf SK 2, on which 60–100% of the trees bloomed in the first year of growth in the garden. Among the studied combinations, the highest rates of crop growth in the Melba variety were noted on the dwarf rootstock SK 3 and semi-dwarf SK 2, in combination with which the variety was characterized by maximum values of average (19.4–16.3 t/ha) and total yield (97.2–81.6 t/ha), with the values of these indicators on the control variants 16.0–10.6 t/ha and 80.2–53.1 t/ha respectively. Low indicators of the periodicity index were noted on the dwarf rootstock SK 3 (15.6) and semi-dwarf rootstock: control M 26 (23.0), SK 2 (20.0), SK 5 (27.5), high index of productivity stability (0.75–0.86) – on rootstocks SK 3, SK 2 and SK 5. In the arid conditions of the Astrakhan region, the zoned variety Melba is recommended to be grown in an intensive garden on rootstocks SK 3 and SK 2, which ensure regular and stable yields.

This paper presents the influence of varieties and different doses of applied nitrogen on grain yield and protein content of triticale. The experiment was set in the period from 2010 to 2012 in the north of Montenegro, in the vicinity of Bijelo Polje. The research included 5 varieties of winter triticale (Odyssey, Kg-20, Triumph, Rtanj and Tango) originating from different breeding houses and the following varieties of fertilization: control (without fertilization), only nitrogen in the amount of 60 kg ha-1 and nitrogen in the amount of 60 and 90 kg ha-1 in combination with the same amount of phosphorus and potassium (80 kg ha-1). The results of the study showed that the lowest average grain yield was obtained in the non-fertilizing variant - control. The use of fertilizers in all tested varieties has led to a very significant increase in yield in all variants compared to control. The Kg-20 variety had the lowest average yield, and the Tango variety had the highest. The highest average protein content was achieved in the fertilizer variant where only nitrogen was used in the amount of 60 kg ha-1. Among the researched varieties, the Triumph variety had the highest protein content in the grains. The data on the achieved yields and the content of protein in grains, depending on the variety and the used doses of fertilizer, indicate the characteristics of individual varieties and can serve as a criterion for the selection of the most suitable variety for certain agroecological conditions. This is particularly important for cattle-oriented farms, where the main priority is to ensure a sufficient amount of quality food.

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”.

Breeding improvement of triticale requires the search for genetic sources for hybridization. Our research aims at identifying high-yielding genotypes of winter triticale and determining the influence of structural elements on this indicator to optimizing selection during the breeding process. In 2014–2018, fifty variety samples of triticale were studied in the North Caucasus Federal Agricultural Research Centre. Soil – ordinary chernozem, medium loamy, medium-thick, low-humus. Black fallow preceded all × Triticosecale Wittmack samples. The experiment was laid having only one replication. The area of the plot was 1 m2. Triticale variety ‘Valentin 90’ served as a standard. We identified 25 medium-yielding and 25 high-yielding varieties. Grain yield in the first group was lower than in the second one and amounted to 784 ± 191 g/m2 and 1024 ± 202 g/m2, respectively. High-yielding samples exceeded the average-yielding ones in the number of spikelets (32.0 ± 2.17 and 31.2 ± 2.18 pieces), grains per ear (69.1 ± 13.0 and 64.5 ± 10.6 pieces) and weight of grain per ear (3.26 ± 0.61 and 3.00 ± 0.61 g). The yield and weight of grain per ear vary significantly (Cv > 20 %). Ear size, number of grains in the ear and spikelet, 1000 grain weight and triticale ear density do not vary much (Cv > 10 %). The most stable trait is the number of spikelets per ear (Cv < 10 %). A weak positive correlation was observed between the yield and number of grains per spikelet (r = 0.18 ± 0.06), yield and ear (r = 0.22 ± 0.06), as well as yield and weight of grain per ear (r = 0.29 ± 0.06). In the group of high-yielding variety samples, there was a reliable weak negative correlation between the yield and number of spikelets per ear (r = −0.32 ± 0.08), between the yield and ear density (r = −0.24 ± 0.09). Grain yield of more than 1.000 g/m2 had the following variety samples – ‘Ugo’, ‘RAH 121/04’, ‘Kitaro’, ‘Tewo’, ‘Ratne’, ‘Slavetne’, ‘Adas’, ‘Dar Belorussii’, ‘Dinamo’, ‘Dinaro’, ‘Liniya 71’, ‘Lamberto’, ‘PRAG 203/1’, ‘Nemchinovsky 1’ and ‘Valentin 90’ (standard).

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.

The paper features the problem of selection of Golden Horde era sites located in the area neighbouring the town of Majary in the territory of the Middle Kuma valley. The bulk of information about the sites is mostly contained in archival documents relating to the 16th – 18th centuries. At present there is information about 9 sites. The locations of five of them have been discovered. Two sites could possibly be locations of the towns of Majary-al-Jedid and Karakogun, which are known due to numismatic and written sources. The medieval climate and landscape in the region allowed to a certain extent cultivating the Kuma river valley, prone to seasonal flooding. Permanent settlements in the area neighbouring Majary could have been founded in the Upland of the Kuma river valley or the terrace areas above the flood plain in the Kuma river valley or the Kuma tributaries. The areas of the estuaries of the left and the right tributaries of the Kuma river seem promising for the search of Golden Horde era artefacts of everyday life. The sites (“Orlovskoye-1”, 13th – 14th centuries, “Preobrazhenskoye-1”) which are situated in the neighborhood of the Madjary hillfort could relate to the rural area around Majary. Specification of a number of sites situated in some distance from Majary requires a more precise definition.
