The process of obtaining high-quality tobacco seeds is very laborious, and at present many operations are performed manually at All-Russian Research Institute of Tobacco, Makhorka and Tobacco Products. The process of obtaining tobacco seeds at the Institute consists of the following operations: harvesting of inflorescences, drying of inflorescences, destruction of inflorescences, screening out coarse impurities, final cleaning in an air stream. An attempt was made earlier to mechanize and improve working conditions at the stage of final purification of the seed mixture. A unit for the final purification of tobacco seeds was developed, manufactured and tested. In this article other modes of final purification of the tobacco seed mixture to improve mechanization and productivity of the same unit have been tested. The seed mix of the 2019 harvest has been used in the studies. Coarse impurities have been separated from the seed mix by sieving through sieves with different hole sizes. Earlier modes of double final purification of seed mixture were proposed. In this research the previously proposed double cleaning modes have been taken as control ones, and in the experiment three-fold modes with a higher feed rate of the seed mixture have been used. As a result, the experimental modes provide identical removal of contaminants, however, the productivity of the unit increases 2 – 3 times due to the shorter total duration of purification, and mechanization is also improved due to a more uniform flow of the seed mixture. In this case, there is no need for the constant presence of an operator, and the process of final purification of the tobacco seed mixture is reduced only to its loading and unloading.

Toxicological assessment is a mandatory research step in the development of new insecticidal drugs. At the All-Russian Research Institute of Veterinary Entomology and Arachnology, a prototype of the insecticidal bait Mukhnet IF was obtained with an active ingredient content of 0.06% ivermectin and 0.015% fipronil, which showed a highly effective effect against houseflies. This work presents the results of the study of acute oral toxicity of the above agent. For this, male white mice with a live weight of 16-26 g were selected. They were kept on a starvation diet for one day in individual houses with water. The drug was given in mg/kg body weight the next day. A total of 33 doses have been tested, ranging from 100 mg/kg to 40,000 mg/kg. The animals were observed for 14 days. According to the research results, it was revealed that at doses up to 20,000 mg/kg there were no signs of intoxication, but when tested at 25,000 mg/kg in some mice, these signs were noted, and at 30,000, 35,000 and 40,000 mg/kg deaths were recorded 20±10, 45±30 and 60±20%, respectively. It was not possible to test the drug over the last above dose due to incomplete eaten by mice. According to the degree of danger for warm-blooded animals, the drug belongs to the 4th class of low-hazard drugs (average lethal dose of 5000 mg/kg or more) in accordance with the classification of GOST 12.1.007-76. When analyzing the literature data on the toxicological characteristics of preparations containing ivermectin and chlorfenapyr, it was revealed that the insecticidal agent in its acute toxicity for warm-blooded animals is comparable to known analogues.

Научная работа выполнена во Всероссийском научно-исследовательском институте люпина в условиях Юго-Западного региона Нечернозёмной зоны Российской Федерации в 2017–2018 годах. Целью исследований было изучение и оценка районированных сортов и перспективных сортообразцов узколистного люпина (Lupinus angustifolius L.) собственной селекции по урожайности зерна, зелёной массы, выходу сырого протеина и других питательных веществ, необходимых при приготовлении кормов для различных животных и птицы. По урожайности зерна (соответственно 3,00 и 2,93 т/га) и зелёной массы (38,3 и 36,3 т/га) выделились новые сортономера Узколистный 53-02 и СмW 62-17. Диапазон превышения по отношению к стандарту по этим показателям составил: по Узколистному 53-02 — 18,1–21,0%, по СмW 62-17 — 22,2–29,0%. Содержание алкалоидов в зерне этих вариантов — 0,041–0,042%. Минимальная алкалоидность (0,038%) отмечена у сортов Белорозовый 144 и Смена. Максимальный сбор белка (1003 кг/га) с урожаем зерна обеспечил Узколистный 53-02; с урожаем зелёноукосной продукции — сорт Белорозовый 144 (1002 кг/га). Максимальное содержание каротина (73,3 мг/кг) получено у сорта Брянский кормовой в фазу цветения. В период технологической спелости зелёной массы по содержанию каротина (45,2 мг/кг) он также был в числе лучших. Во Всероссийском НИИ люпина разработаны сбалансированные по необходимым питательным веществам рационы с использованием зерна и зелёной массы различных сортов узколистного люпина и проведены многочисленные опыты на различных производственных группах крупного рогатого скота, свиньях и птице. Привлекательность узколистного люпина для использования в производстве связана с тем, что из крупносемянных видов он один из самых скороспелых, холодостойких и устойчивых к антракнозу. The research was conducted in the Southwest region of the Non-Chernozem zone of Russia in 2017–2018. The aim was to evaluate promising genotypes of blue lupine (Lupinus angustifolius L.) regarding their grain productivity, yields of green mass, crude protein and other valuable nutrients for livestock feeding. “Uzkolistnyy 53-02” and SmW 62-17 genotypes had the highest productivity of grain (3.00 and 2.93 t ha-1) and green mass (38.3 and 36.3 t ha-1, respectively). Hence yield increases amounted to 18.1–21.0% (“Uzkolistnyy 53-02”) and 22.2–29.0% (SmW 62-17), respectively. Alkaloid concentration reached 0.041–0.042% in their grain. Grains of “Belorozovyy 144” and “Smena” varieties accumulated the least alkaloids. Grain of “Uzkolistnyy 53-02” and green mass of “Belorozovyy 144” were rich in protein — 1003 and 1002 kg ha-1, respectively. “Bryanskiy kormovoy” had the highest carotene content of 73.3 mg/kg at flowering time. It showed high carotene concentration also at green mass maturity stage. The All-Russian Research Institute of Lupine developed balanced diets for grain and green forage from blue lupine and tested their effect on cattle, pigs, and poultry. Blue lupine is a valuable crop for forage production due to large seed size, early ripeness as well as resistance to cold and pod spot.

In the presented studies the genotypes of 46 varieties of red currant (Ribes rubrum) from the All-Russian Research Institute of Fruit Crops Breeding (VNIISPK) the collection were studied for 14 microsatellite locus. The data were obtained by the detection method of – fragment analysis using capillary electrophoresis. Varieties with rare, unique alleles and combinations of alleles have been identified. In most cases, no more than two fragments were identified for each genotype for a specific locus, but three fragments at some loci were amplified in the samples (Orlovchanka, Konstantinovskaya, Nadezhda – e3-B02; Marmeladnitsa – g2-G12; Nadezhda – g2-J08; Svetlitsa, Tatianina – g1-L12). The profiles of the cultivars Cascad and Red cross are identical to each other, although they differ from the others. The Red cross [(Cherry × White Grape] and Cascad [(free pollination of the variety Diploma (Cherry × White grape)]] varieties were developed in the USA and have common ancestors. It can be assumed the collection under different names contains the same genotype or that these pairs of varieties are so similar that the polymorphism of the analyzed loci is not enough to distinguish them. To prevent a shift in the size of alleles control varieties were selected and proposed, zoned in the territory of the Russian Federation – Gazelle (originator of VNIISPK: Chulkovskaya × Maarses Prominent) and Valentinovka (originator of VNIISPK: Rote Shpetlese × Jonker van Tets). The data obtained on the polymorphism microsatellite loci Red currant can be used for further identification.

This paper presents the results of the research carried out in the All-Russian Research Institute of Reclaimed Lands. It has been established that land improvement techniques increased the integral index of physical soil conditions from 0.41-0.60 to 0.80-0.86. The soil demonstrated a greater total number of microorganisms, as well as certain physiological groups such as actinomycetes, autochthonous and especially nitrogen-fixers; but the number of fungi and denitrifiers, as well as the fungi causing the Fusarium wilt of the plants, decreased.Average crops increase achieved with the help of deep reclaiming band tillage of drained gleyish soil to depth 50-60 cm was 9.0-24.1% in both wet and dry years. This land improvement technique effect lasts for two-three years or longer. The ridged plowing compared to the ordinary plowing raised the spring crops by 0.55-0.61 ton/ha (by 16.9-17.5%) without making any additional expenditures.

The paper presents the results of technological evaluation of red wine varieties breeded by All-Russian Research Institute for Viticulture and Winemaking: Vesta, Cherny, Zhemchug, Au-gusta, Teremnoy, Mugofir. These varieties are characterized by high sugar accumulation. Li-queur wines were prepared using classical tech-nology. The research was conducted in the la-boratory of wine technology in micro-wine production. The weight of one batch of grapes was 10–25 kg. The main physical and chemical parameters of wort and wine were determined. Wine distillate was used as an alcoholic agent. For maintaining and enhancing the varietal aroma of grapes we used technology of frac-tional alcoholization. With the help of degusta-tions, organoleptic characteristics of the ob-tained samples of liqueur wines were carried out, as a result of which preliminary conclusions were made about the feasibility of using the studied varieties for the preparation of red li-queur wines. All the studied grape varieties can be recommended for the production of liqueur wines, pink and red.

The development of the table grapes market is directly related to the renewal of the assort-ment and technological modernization of pro-duction, taking into account the growing re-quirements of consumers. Equally important is the discrepancy between the tastes of con-sumers of fresh grapes and the quality indica-tors of the grapes supplied by the industry, therefore, an important task is to improve the assortment. Recently, a large number of pri-vate breeders have joined the breeding work on the breeding of table varieties, the results of whose work often have no scientific as-sessment. The article presents the results of a variety study of five selected promising table hybrid forms of grapes obtained by amateur winegrowers. Variety studies were conducted in 2018–2020 at the experimental vineyard of the experimental field All-Russian Research Institute for Viticulture and Winemaking – Branch of Federal State Budget Scientific In-stitution «FRARC». The methods used for the assessment were generally accepted in vit-iculture. Vineyards grafted, covering, non-irrigated, planting scheme 3×1.5 m. The agro-biological characteristics are given, the yield is estimated, the uvological, tasting and eco-nomic assessment of hybrid forms is given. The studied varieties have desirable character-istics: high quality, attractive appearance, large and very large bunches and berries, dense pulp consistency, different tastes, bright color of berries.

The article presents research data on the de-pendence between the yield and quality of grapes and shoot load. The studies were car-ried out at the All-Russian Research Institute of Viticulture and Winemaking named after Ya.I. Potapenko, Novocherkassk, Rostov re-gion. On the root-own vineyards of the Per-venets Magaracha variety tolerant to phyllox-era, the following load rates were studied: 30; 35; 40; 45 shoots per bush. For two years of research, the maximum yield was obtained in plantations with a load of 45 shoots per plant: in 2019 - 23.2; in 2020 - 14.7 t / ha with the mass concentration of sugars in berry juice 183 and 170 g / dm3, respectively. The best indicators of the quality of grapes were marked in the variant with the minimum load of shoots in the experiment: the mass concen-tration of sugars in berry juice was 196 g / dm3 in 2019 and 180 g / dm3 in 2020; the concentration of titratable acids was 7.6 and 8.8 g / dm3, respectively.
