The article discusses the issues of import substitution in the market of agricultural products and resources for their production in Russian Federation, ensuring the country's food security. Research results show that since 2014, when the active import substitution policy began, there have been significant changes in the agri-food trade, characterized by a decline in imports and an increase in exports. However, in different product segments of the market the speed of these changes varies. Despite ensuring the country's food independence for most types of agricultural products, the dependence on the import of resources for its production remains significant. At the same time, the demand for agricultural products remains under pressure from declining household income, as well as a significant income differentiation. In this regard, suggestions were made for making adjustments to the doctrine of food security, primarily in terms of assessing the economic affordability of food. Also, an assessment was made of the changes made to the state program for the development of agriculture in conjunction with the strategic objectives of the development of the Russian Federation defined for the period up to 2024. The need to ensure consistency between the tasks assigned to the agro-industrial complex to achieve the country's food security, increasing the export potential of the domestic agri-food products and resources allocated for development, was noted.

Problems of proper nutrition and health of citizens are becoming increasingly important every year. A significant number of chronic non-communicable diseases have been observed in Russia and its regions for several years. Thus, according to the Territorial body of the Federal state statistics service for the Irkutsk region in 2017, the mortality rate from diseases of the circulatory system was 615 people per 100 thousand people, 218 people per 100 thousand people died from neoplasms. The reason for the increase in the incidence of population researchers believe the change in socio-economic structure, lifestyle and diet. At the same time, the President of the Russian Federation defined the task of achieving the average life expectancy of Russians at the level of 78 years in the may Decree of 2018. Currently, for the Irkutsk region, this figure is at the level of only 69 years and at the current rate of growth by 2024 will reach only 75 years. In this regard, we need a set of measures aimed at improving the health, living and working conditions of citizens of the country, which can be implemented, including through ensuring a normal diet of life and consumption of basic products, including vegetables, at a level not lower than the rational norms of their consumption. The article presents an assessment of the capacity and potential of the market of vegetable products on the materials of the Irkutsk region, the main producers, exporters, importers of vegetables, the forecast of shortage of vegetables. Social efficiency in achieving the proposed performance indicators will be determined by increasing the life expectancy of the population, reducing morbidity, improving the quality of life of those suffering from diseases associated with malnutrition, and the ratio of the obtained favorable social results to the costs to achieve them. Economic efficiency will be expressed by assessing the impact of the results achieved in the framework of program activities on the formation of the gross product, ensuring the dynamics of economic growth and increasing productivity, as stated in the presidential decree and Federal national projects until 2024. The practical application of vegetable demand calculations in accordance with rational consumption norms can be used in the process of marketing research to identify the potential market entry of new players or increase the production of fresh vegetables by their existing producers.

The article presents the results of research on the production in vitro of regenerated plants from the seeds of cultivars of lettuce (Lactuca sativa L.) Emerald, Bouquet, Chameleon (FSBSI Federal Scientific Vegetable Center), susceptible of aspermia tomato (Tomato aspermy cucumovirus) – AsTV. Seeds of strongly susceptible to AsTV varieties of salad Chameleon and Bouquet were subjected to thermotherapy at different temperatures (37°C, 38°C, 40°C) for a different time interval (1, 3, 5, 7, 10 days) in dry form and when moistened. Marked varietal specificity during germination of seeds after thermotherapy. Thus, the greatest number of seedlings in the emerald variety was obtained after 5 days of thermotherapy (10.0±0), while the Bouquet variety had the best results after 3 days of thermotherapy (9.3±1.2) with moisture. After thermotherapy of dry seeds by 40°C plant material of cultivar Emerald was planted on solid and liquid culture media. The conditions of step sterilization of lettuce seeds for introduction into the culture in vitro were chosen: washing in 96% ethanol, then in 50% aqueous solution of "Whiteness" with the addition of Twin-20, after in sterile distilled water. The nutrient medium for germination of lettuce seeds was used: Gamborg B5 (2% sucrose, 7.0 g/l agar), and the liquid nutrient medium was of that composition. The obtained seedlings were cutted and transferred to medium MS (2% sucrose, 0.1 mg/l ha and 1 mg/l BAP, 3.0 g/l phytogel). The formed shoots for rooting were transferred to the MS medium (2% sucrose, 3.0 g/l phytogel). In the future, lettuce plants will be adapted in vivo and tested for the presence of tomato aspermia virus in the planting material.

At the first stage of breeding, the new source material was created to obtain a variety of daikon resistant to abiotic factors with high productivity and commercial qualities, better taste, and biochemical properties. Eighteen samples from Russia, Ukraine, Belarus, China, Korea, and Japan were in the nursery of the original forms. The following breeding types were used in the hybrid nursery: 1) crossing of several morphologically close samples originating from geographically remote areas; 2) paired crosses of morphologically and biologically different samples. Breeding was carried out on an accelerated scheme: before harvesting, samples were evaluated for resistance to bolting, shape and color of the roots, taste qualities, and affection with diseases; in February, the roots were planted in temporary greenhouses in pairs for hybridization; seeds were threshed in mid-July; the hybrid seeds were sown on the roots in early August; the roots were harvested and evaluated 60-65 days after the moment of sprouting. Then, the 1.5-year cycle was repeated until the constant lines were obtained. Yield fluctuations were determined by taking into account the sum of effective temperatures and precipitation for the period “sprouting – harvest” [4]. Slight variability in the yield at high agronomic stability was observed for the varieties Sokol, Gulliver, and hybrid No. 41. The standard (variety Klyk slona) differed from other varieties by high variability in the yield and insufficiently high agronomic stability (66%). We found that there was the fluctuation of the yield of modern varieties: Klyk slona by 22 t/ha, Gulliver by 9 t/ha, Sokol by 14 t/ha, and hybrid No. 41 by 15 t/ha. It was estimated that for every 1 degree Celsius rise in the amounts of effective temperatures the yield of the aforementioned varieties decreased: 9.7; 38; 7.4 and 66 kg/ha, respectively. And, vice versa, if the amount of precipitation increased by 1 mm, the yield of Klyk slona would increase by 17 kg/ha, Gulliver - by 10 kg/ha, Sokol - by 11 kg/ha, and hybrid No. 41 – by 6 kg/ha. The technology and method for initial seed production of daikon have been developed with the preserved economic and biological characteristics. The daikon variety Sokol was created and included in the State Register.

The main direction of breeding in melon farming is the creation of varieties with high potential for productivity. The research was conducted at the Bykovskaya experimental station in the Volgograd region. The aim of the research was to create a new competitive watermelon variety malachite, which has a complex of useful and economic characteristics, resistant to biotic and abiotic environmental factors. The characteristic of the initial forms used for hybridization is given. The data of evaluation of the hybrid combination in all stages of the breeding process. According to the results of the 3-year competitive variety testing, the excess of the yield of watermelon malachite over the Sinchevsky standard averaged 1.5 t/ha. The dry matter content for all years of research was at the level of the standard and ranged from 11.4 to 12.4%. The final result of breeding work is the creation of mediumgrade watermelon malachite, which is in the state variety testing.

Breeding of high-tech varieties of vegetable peas is a priority ефыл selection at the present stage. The main requirement of processing enterprises is full and timely loading of production lines with high-quality raw materials. Peas should be aligned in size, of intense green color with high biochemical parameters. Therefore, the newly created varieties should combine a number of characteristics: high and stable yields, simultaneous ripening, resistance of the stem to lodging, resistance to most common diseases. The combination of these features allows to realize the potential of the culture fully, and to find wide application in production for created varieties. Since the 80s of the last century, FSBSI «FSVC» (Moscow region) has been actively working to increase the suitability of vegetable pea varieties for mechanized harvesting. Since these years, a number of varieties with strong shortened internodes and stem height not more than 80-90 cm have been created. Reducing plant height has improved the manufacturability of vegetable pea varieties, the stems resistance to lodging during the technical stage of ripeness has been significantly increased. However, in the biological stage of ripeness, the stem degree of lodging has been preserved, which creates additional difficulties in the seed production of vegetable peas. Since 2008, the direction of breeding has been adjusted to improve the stems resistance to lodging in combination with other economically significant traits (determinant type of growth, mustache type of leaf, green color of peas, duration of the technical stage of ripeness). As a result of this work, new varieties Cruiser, Viking, Triumph, Corsair, Barin, Hercules, Egorka have been created. The work is to introduce these varieties into production is being carried.

The volume and structure of sown areas of vegetable pea varieties of different terms of ripening, selection of the Krymsk Experiment Plant Breeding Station, VIR in the southern region of Russia is shown. When creating new varieties, at present, priority is given to obtaining very early and early, in order to expand the conveyer of raw materials for processing. The merits of the breeding achievements created and included in the State Register are shown: a very early variety Prima (year of inclusion 2016) and an early Kudodesnik 2 (2018), which have already begun to be used in production. However, for processing enterprises in each group of ripening it is necessary to have 2-3 varieties. Therefore, we have set a goal - to create new varieties of vegetable peas of very early and early ripening periods, adaptive to the climatic conditions of the North Caucasus region. The studies were carried out from 2016 to 2018 in breeding fields (Krymsk Experiment Plant Breeding Station, VIR, Krasnodar region). Studied 10 varieties and lines. According to the results of evaluation in competitive variety testing (in 2016-2017), a very early grade of vegetable peas Izyuminka was transferred to the state test. The variety ripens 9 days earlier than the Alpha standard and surpasses it in yield (by 2.2 t / ha.). According to the competitive test held in 2017-2018, in 2019, the early variety Mayak was transferred to the state variety testing, which ripens 4 days earlier than the standard and is almost twice as high in yield. The use of these varieties in the processing industry will significantly increase the period of receipt of grain for processing.

Expanding the range of vegetable crops, including green ones, through the introduction of new varieties into production is an important task. The study and evaluation of the original material of the salad, the features of cultivation in different periods, will allow to identify samples of a complex of economically valuable traits for the selection of culture, which is relevant for the creation of varieties in Belarus. Research was carried out on the experimental field of the Department of horticulture of the Belarusian state agricultural Academy in 2013-2015. The article assesses the relationship between the main economically valuable features of varieties of lettuce when grown in the spring (seedling method) and spring and summer sowing in the open ground. In lettuce plants of the headed variety, the sign “the mass of the vegetative part of the plant” strongly depends on the sign “diameter of the head” (r=0.640 - with the seedling method and r=0.809 - with the spring sowing period), “leaf width” (r=0.685 and r=0.790, respectively). A high connection is also established between the signs "leaf length" and "leaf width" (r=0.702 - with the spring sowing period and r=0.749 - with the seedling method). In leaf lettuce plants, a strong correlation was noted between the signs “leaf length” and “plant height” (r=0.706 for summer and r=0.810 for spring planting), diameter of the rosette of leaves (r=0.564 for summer and r=0.810 - at the spring sowing time). The average feedback for leaf lettuce varieties is revealed between the signs “leaf width” and “number of leaves” (r=-0.444 - for spring and r=-0.458 - for summer sowing time). The majority of morphological signs, depending on the time of cultivation, are related to each other by average correlation links (the correlation coefficient ranged from 0.458 to 0.531).

Primal problem of vegetable growing is constant supply of the population with all types of vegetables, including green cultures. Green cultures are vegetables that have high nutritional value and precocity. However they often are infected by phytopathogenic microorganisms already at initial stages of ontogenesis at cultivation in closed soil conditions. It leads to emergence of disjointed shoots, deterioration of growth and development of plants and loss of quality. Now in the Republic of Belarus a number of biological substances on the basis of bacteria Bacillus was developed. They are used against diseases of plants of mushroom and bacterial etiology. However there is not information about influence of bacteria on quality of products of green cultures. The aim of the work was studying of influence of two strains of bacteria Bacillus that were introduced in peat substrate on efficiency and quality of lettuce. Two strains of bacteria Bacillus were used in the work. They were selected from the soil. The strains are Bacillus subtilis M9/6 and Bacillus amyloliquefaciens 23TM that have high antagonistic activity to a wide range of phytopathogens. Cultivation of plants carried out in containers of 250 ml under light installations with illuminating intensity 13-15 thousand luxury and lasting irradiating of 14 hours before technical ripeness of lettuce. It was established that the application of strain Bacillus subtilis M9/6 (in concentration 10⁶ cells/ml, 10 ml/l of substrate) and the strain Bacillus amyloliquefaciens 23TM (5 ml/l of substrate) in substrate before sowing increased nutrition value of lettuce. Dry matter content, water-soluble carbohydrates (mono - and disaccharides) content and vitamin C content increased. The bacterial strain B. amyloliquefaciens 23TM also promoted accumulation of vitamin B2. The content of nitrates in lettuce leaves decreased on 50,3% and 39,1%, respectively. It was shown that the application of bacteria in substrate before sowing of crop has a greater influence on quality of lettuce, than watering of shoots.

Succulent plants are of a special interest for Russian botanical gardens’ collections, many of them are meant to be used not only in phytodesign but in pharmacy while drug manufacturing. The analysis of a species composition of the Nikitsky botanical gardens’ collection of officinal succulents is among high-priority tasks as it will highlight that advanced species for research and growth and development special aspects’ study in the introduction conditions, bioactive substances’ content in them and replenish the collection with new taxons, that are notable not only decorative characteristics but for officinal properties. The officinal succulents Aloe vera (L.) Burm. f., Aloe arborescens Mill., Sansivieria trifasciata Prain, Opuntia ficusindica  (L.) Mill., Pereskia aculeata Mill., Selenicereus grandiflorus (L.) Britton & Rose, Crassula ovata (Mill.) Druce, Kalanchoe daigremontiana Raym. Hamet & H. Perrier, with the complex of bioactive substances and a wide range of a human exposure, are exposed in the collection of the Nikitsky botanical gardens. They deserve a general pharmaceutical application while drug and cosmetic products’ manufacturing. The collection of the succulents in the Nikitsky botanical gardens was started to form in the years of 1812-1824. The total area of a new greenhouse, that was opened in 1996, is 960 square meters. The main part of the succulent collection of 985 taxons, including 87 subspecies, 38 subvarieties, 70 forms, 13 cultivars, is contained in it. Many plants are presented in the open field exposition with the total area of 1,240 square meters.

Tarragon (Artemisia dracunculus L.) is a spicy aromatic culture, perspective to use in the food and medical industry. In the collection of aromatic and medicinal plants of the Nikita Botanical Gardens, tarragon is represented by two varieties: Isumrud and Travnevy. The Isumrud variety is characterized by a high content of essential oil (0.6% of the wet weight) of the methylchavicol chemotype (the main component of the essential oil is methylchavicol, whose mass fraction is up to 91%) and is perspective to use not only as a spice, but also in medicine as a reducing facilities. The variety Travnevy contains only 0.1% of the essential oil from the wet mass of the sabineno-elemicin chemotype (the main components of the essential oil are sabinen (40.0%) and trans-from-iso-elemicin – 26.1%), characterized by high productivity of the aerial mass (12 kg/m² ), the main direction of use in the food industry as a spice. Due to the lack of requirements for dry raw tarragon, we have developed a draft technical specifications for dry crushed tarragon raw materials TS 01.28.30-009-01579640-2018. Specifications apply to dried whole and crushed raw materials, intended for the manufacture of water and water-alcohol infusions, as a source of biologically active substances, as a component for seasonings to meat, fish dishes, for use in cooking, as well as in the production of alcohol and soft drinks. The main physicochemical indicators of whole and crushed tarragon raw materials (type, size, smell, taste, mass fraction of essential oil, impurities, moisture, ash) are presented.

The production of functional food products is one of the most important directions of development of the food industry. Particular attention is paid to the creation of new balanced in composition of products enriched with functional components, allowing them to increase their nutritional and biological value. Among vegetable crops, pumpkin is a highly valuable raw material in the food industry, which has equally both nutritional and biological value, and allowing for the correction of the human nutritional status. Based on this, we has been assessed the biochemical indicators of the varieties and hybrids of table pumpkin during to keeping as a perspectives raw material for the products of functional allocation in the Far East region. The research was carried out by the department of vegetable crops and potatoes of the Far Eastern Research Institute of Agriculture in the framework of the Far East program. Biochemical studies on pumpkin were carried out in the laboratory of agriculture of the Far Eastern Research Institute of Agriculture and in the laboratory of testing of the Center for Agrochemical Service “Khabarovsk” three times: 1 - before laying on to keeping; 2 - after 1.5 months of keeping; 3 - 1 month after the previous study. The results of studies showed that the varieties Nadezhda, Zimnyaya sladkay and Japanese hybrid Orange colon after 2.5 months of keeping, there was a decrease in some biochemical parameters. The varieties Vnuchka, Zhemchuzhina and a Japanese hybrid Sweet kob there is a tendency to increase almost all the quality indicators during the whole period of keeping. The content of dry matter, Vitamin C and potassium increases significantly. A favorable period for the processing of raw materials in the manufacture of the products of functional allocation is 1-2 months after harvesting for the Nadezhda variety and 1-4 months for the Vnuchka variety. Perspectives for the Far Eastern region in the manufacture of the products of functional allocation from foreign varieties are the Zimnyaya sladkay variety and the Japanese hybrid Orange colon.

This article presents the results of studying the effect of ultrasound on the consistency of products. The task of the study was to identify the possibility of using ultrasound to change the consistency of the product from puree to homogenized. For this purpose, laboratory samples of apple puree were periodically processed on an ultrasonic generator at a frequency of 21.7 kHz, for different duration of exposure to ultrasound from 1 minute to 20 minutes. After processing, measurements of physicochemical parameters were carried out the mass fraction of soluble solids, temperature and viscosity. When analyzing the obtained results, it was found that, depending on the exposure time, the indicators of the mass fraction of dry substances in samples No.1, No.2, No.3 slightly increased relative to the control sample from a value of 11.9 to 12.4 V of sample No.4, in which the duration of exposure to ultrasound was 20 minutes, the indicator of the mass fraction of dry substances increased more significantly up to 13.8%. The same dynamics is observed in the obtained values of the viscosity of the product, which gradually increases in proportion to the exposure time from sample No.1 to sample No.4 (4600-6500 Centipoise (CP)). In addition, a comparative assessment of the organoleptic characteristics of experimental samples (taste, color, aroma and texture) was carried out after their ultrasonic treatment, depending on the duration of exposure. It was found that all the organoleptic characteristics of apple puree with an increase in the duration of ultrasonic treatment with a given parameter at a frequency of 21.7 kHz, changed depending on the time of exposure. Thus, the consistency changed from a “granular” structure (in the control sample) to a homogeneous homogenized (in sample No.3). In sample No.4 (with an exposure time of 20 minutes), mashed potatoes were obtained with a fine, finely divided creamy mass. Consequently, the effect of ultrasound with a given frequency of 21.7 kHz for at least 10 minutes allows a pureed product with a puree-like structure to obtain a homogenized puree.

Often in the soils of crop rotations of grain crops, including on black soil, the content of mobile forms of copper, manganese, zinc and other trace elements is low. Improving the efficiency of making micronutrients for grain crops and determining the best ways and doses of their introduction are topical issues that need to be addressed in order to increase the productivity of crops. The purpose of research is to identify the effectiveness of the use of water soluble compound fertilizer with microelements of the company “Haifa Chemicals” in the technology of growing winter wheat on leached chernozem under conditions of the Oryol Region. Field production experiments were established in 2017-2018 on the basis of Orlovsky Leader LLC Branch №5” located in Livensky district. Field experience with the use of Haifa Chemicals products: Poly-Feed micronutrients 19-19-19 + 1MgO + ME and Poly-Feed 6-15-38 + 3 + ME was laid on soft winter wheat varieties Moskovskaya-56.The control variant was the basic technological scheme used in the household for carrying out leaf dressings with mineral fertilizers together with the organic fertilizer Gumostim. As a result of the research, it has been established that the use of double foliar feeding water soluble compound fertilizer with microelements Poly-Feed 19-19-19 + 1MgO + ME in the tillering stage and at the end of flowering and a single Poly-Feed 6-15-38 + 3 + IU in the subflag phase - flag leaf, increases the height of the plants, as well as the productive characteristics of the ear: the size of the ear, the number of grains in the ear, the mass of grains and their best quality, which in general provides a reliable increase in the yield of grain of winter wheat. At the same time, it was found that, due to leaf feeding, the impact of adverse weather conditions under which the development of winter wheat plants took place in 2018 and their productive properties were laid was leveled out. Due to relatively low additional costs, the use of complex fertilizers of the Poly-Feed brand for winter wheat is economically feasible and can bring additional economic income: based on the maximum level of minimum prices for the grain of the 2018 harvest, it will be 2.07-2.28 thousand rubles / ha regarding base technology. Thus, water-soluble fertilizers, which include Poly-Feed company "Haifa Chemicals" are recommended to domestic agricultural producers for mass introduction in practice of the technology of intensive sheet nutrition of grain and other crops.

Potatoes is the most important food crop, one of the main crops grown throughout the world. A way to improve the profitability of the potato industry is processing. The processing production requires special varieties of potatoes. Tests were carried out by the department of vegetable breeding «Agrarian scientific center of republic of Dagestan» in 2017-2018 with the purpose of study the effect of soil-climatic conditions of Dagestan highlands on dry matter and starch content in potato tubers for production of processed potato products. Processing of potatoes is one of the methods to increase profitability of industry. One of the quality indexes of the use of potato varieties for their processing is high level of dry matter and starch. As a result of the research, the following varieties were identified: high-yielding are Impala, Irbit, Zhukovsky Ranniy, Manifesto, Matushka, Nevsky, Primabella, Rosara, Silvana, Spiridon and Udacha; high dry matter content are Alena, Vektor, Dzhokonda, Desiree, Matushka, Nart, Primabella and Rossi; high in starch: Desiree - 23%, Vector and Primabella - 22.2% each. The results of the present investigation revealed that climate of the mountainous areas of Dagestan republic promotes the increase of dry matter and starch content in potato tubers by 3-4%.

There are no doubts about the advantages of using drip irrigation, however, it does not solve the problem of regulating plant phytoclimate in open ground during periods of high temperatures in the Lower Volga region when the biological development of vegetable crops is inhibited, which leads to a decrease in yield. The use of combined irrigation in the combination of drip and fine solves the problem of reducing thermal stress and increases moisture on the soil surface. Based on the research and publications of Russian scientists, the main requirements for the functioning of combined irrigation systems have been identified. These include the provision of drip and fine (aerosol) irrigation, the system should work both jointly and separately, the regulation of plant phytoclimate, the possibility of using foliar feeding and chemical protection, etc. To solve this problem, a number of technical solutions have been considered, which will allow to partially or fully satisfy all the requirements for the stability of the technological process of growing crops under combined irrigation and eliminate the above-mentioned negative environmental conditions of the Lower Volga region. The FGBNU VNII “Raduga” developed the KAU-1M aerosol humidification kit, and the scientists of the Volgograd State Agrarian University developed technical solutions Spray Nozzle of the Combined Irrigation System for Cultivation of Vegetable Crops). The proposed technical solutions for the combined irrigation system will improve operational reliability, provide the plants with soil moisture, control the temperature, nutritional regime of the plants, which will make it possible to obtain stable yields of agricultural crops and environmental safety of the environment.

Black rot (pathogen – Xanthomonas campestris pv. campestris) is one of the most harmful diseases of brassicas. Seedlings growing in trays in greenhouse can meet rapid spreading of the pathogen and heavy yield loss even at very low seed infection level. This work was targeted on efficiency comparison for different plant protection agents against black root infection in seeds. Antibacterial effect of the agents was tested in vitro by well diffusion, direct placement of the agent onto bacterial lawn, and by incubation of bacterial suspension with the agents. Biological efficiency of the agents against seed infection was tests by seed soaking or by wet treatment. High antibacterial effect against black rot pathogen in vitro was shown for bacteriophage cocktail, Biocomposite-correct, Zeroxxe, Peroxyacetic acid (NUK15), Ps 11, and Kocide 2000. Highest biological efficiency against seed infection by black rot was shown for bacteriophage cocktail, Biocomposite-correct, Zeroxxe, Peroxyacetic acid (NUK15), and Kocide 2000.

The article presents the results of research on the biology of willow-carrot aphid and evaluation of varieties and hybrids of garden carrot in the Bryansk region. The aim of scientific research was to study the biological characteristics of willow-carrot aphid - Cavariella aegopodii (Scop.) (Homoptera: Aphididae), the influence of weather and climatic conditions on the pest prevalence, the degree of plant population, as well as the evaluation of varieties and hybrids of garden carrot on the complex of economically valuable traits. It was established that the average daily temperature of 18°C and above contributed to the intensive pest infestation of carrot plants in the first decade of July. The peak of the number of willow-carrot aphids was noted in I-II decades of July. With the increase of temperature increased the fecundity of females of the aphid up to 60-70 larvae. In 2017-2018 detected relatively resistant varieties and hybrids of garden carrot – Minor, Marlinka, Nantskaya 4, Nadezhda F₁with an average damage score of 1.0-1.17. The variety Shantena royal is marked with plants with an average score of 2.43, which characterizes the average resistance of the variety to damage. In the Bryansk region on the basis of "mass of roots" on average, over two years of research significantly exceeded the standard (variety Nante 4) Shantena 2461, Shantena Royal, Minor, Nante, Cupar F₁, Nadezhda F₁, Mars F₁ by 6.2 - 37.1 per cent. On the basis of "marketable yield" varieties and hybrids of Mars F₁, Cupar F₁, Nadezhda F₁, Shantena royal, Nante, Minor were distinguished. According to the results of biochemical analysis, a variety of Nante with a high content of carotene (185.1 mg/kg), dry matter (13.3%) and low nitrate accumulation (110.2 mg/kg) was isolated. During two years of research in the conditions of the Bryansk region, it was established that Minor, Nadezhda F₁ combined relative resistance to willow-carrot aphids damage and were distinguished on the basis of “commercial yield”.

Increasing popularity of asparagus bean (Vigna unguiculata (L.) Walp.) − a new for Russia vegetable crop requires comprehensive study including resistance to biotic environmental factors. Composition of pathogens of germinating seeds, plants (roots, leaves, stems, fruits) of large collection of asparagus bean from the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) and the Bioresource Scientific Collection of the CSBG SB RAS UNU No. USU 440534 have been investigated. Plants of 87 samples of asparagus bean were grown in the unheated plastic film greenhouse on the south of Western Siberia (54 ° N lat. 83 ° E) and examined for infestations of diseases in the Central Siberian Botanical Garden and Novosibirsk State Agrarian University (Novosibirsk). The infection of seeds with pathogenic micromycetes was determined according to GOST 12044-93 (similar to common beans) using the methods of mycological analysis and the Petri-dish moist chambers, also on Chapek media and KDA media. The main pathogenic micromycetes are: on germinating seeds − species of the genera Fusarium, Aspergillus, Penicillium, Alternaria, Mucor, Botrytis cinerea, Sclerotinia sclerotiorum; on seedlings − Fusarium solani; during fruiting on fruits and stems − B. cinerea and S. sclerotiorum; on the root collar − S. sclerotiorum. The dominant forms of white mold were stem, root collar, fruits. Five samples that showed a high level of resistance to B.cinerea and S.sclerotiorum have been selected. System for asparagus bean disease surveillance which should be built in the calendar-phenological sequence, has been recommended.
