Relevance. Currently, in many countries of the world, the production of non-season raspberry berry products has become widespread. Recently, interest in this technology has arisen in Russia, which has great prospects for the development of industrial gardening. In our opinion, it is promising to develop elements of technology for the non-seasonal production of red raspberries, propagated by the method of clonal micropropagation with a traditional and remontant type of fruiting in the conditions of winter heated greenhouses.Material and methods. The experiments were carried out in the laboratory of clonal micropropagation of garden plants in the fruit growing laboratory of RGAU-MSHA named after K.A. Timiryazev. The objects of research were varieties of red raspberries with a traditional (variety Volnitsa) and remontant (varieties Orangevoe Chudo and Bryanskoe Divo) type of fruiting. The experimental plants were propagated by the method of clonal micropropagation and grown before distillation in open and protected ground; plants propagated by root offspring served as control. Experimental plants were planted in open ground for growing in mid-May, in mid-October they were transplanted into 10 liter containers and transferred to protected ground conditions. Then put in the refrigerator compartment with a temperature of + 1 ... + 5°C. For distillation, the raspberry repairing plants were exposed in the winter heated greenhouse on January 20, while the shoots of replacing the aboveground system were normalized: without normalization, 3 shoots per plant, complete pruning of the aboveground system. Raspberries with a traditional type of fruiting were exposed in a winter heated greenhouse in three periods on January 20, February 10, March 2. Accounting for the passage of the phenological phases of development and yield was made for 3 months every 5 days.Results. In the conditions of winter heated greenhouses, efficiency has been shown and elements of technology for non-season production of raspberry berries remontant and berries with a traditional type of fruiting, propagated in vitro and grown before open field distillation are developed. It was revealed that it is necessary to normalize the shoots before distillation of raspberry remontant, and the optimal timing for the start of distillation for raspberries with a traditional type of fruiting has been established.

Relevance The structure of the flowers of tomatoes is very thin adapted to self-pollination, and any violations of the technology of cultivation in protected ground lead to a significant reduction in the ability of plants to pollinate and fruit set. Violation of growing conditions can lead to changes in the structure of the inflorescences and flowers, which negatively affects pollination and fruit formation, reducing the yield. The article presents a review of literature data and the author’s own research on this topic. It has been established that growing conditions in cultivation structures have a greater effect on the amount of pollen produced in tomato flowers and to a lesser extent, on its quality. In the flowers of the first inflorescence, the least amount of pollen is produced. This is due to the fact that the formation of this inflorescence occurs in the seedling period, while it is experiencing more stress. Basal (the first in the inflorescence) flowers produce low-quality pollen, while its amount is maximum. Additional pollination improves fruit set by increasing the amount of pollen grains falling on the stigma of the pistil. The use of bumblebees for additional pollination increases the yield by increasing the number of ensuing fruits. The formation of polynomial flowers on tomato plants – varietal reaction. More often they are found in multi-chamber largefruited tomato hybrids. Less commonly, polynomial flowers are found in tomato hybrids with plum and pepper fruits, such flowers are not found in cherry tomato hybrids. A polynomial flower - most often the first in the inflorescence. They are formed mainly in the first 4-5 inflorescences and give accreted non-harvest fruits. In order to increase the yield and quality of fruits, polynomials need to be removed in a timely manner.

RelevanceRecently, breeding work with cabbage is aimed at developing F1 hybrids, which provide the population with year-round production. The main requirements for hybrids: excellent presentation with appropriate taste, high yield stability, morphological uniformity, resistance to major diseases and tolerance to pests, as well as high keeping quality during storage. In recent years, tobacco thrips is a serious problem for cultivation of cabbage. Plant resistance to tobacco thrips is becoming increasingly relevant, at the moment in the conditions of Krasnodar region. Since tobacco thrips is the most dangerous pest in the south and quickly adapts to poisons, development of resistant hybrids should be considered the most effective way to control.Methods The purpose of breeding work is to identify highly productive cabbage hybrids with high tolerance to tobacco thrips. It was previously found that late-ripening hybrids are less affected. Therefore, in our studies, we evaluated the effect of growing terms of the same hybrids in different years of research and on their damage with Thrips tabaci Lindeman. The direction of this work is to evaluate hybrids of cabbage for leaf damage by tobacco thrips and to identify sustainable hybrid combinations and their parental forms. Studies were carried out in the central soil-climatic zone of the Krasnodar Territory. The object of research was medium-ripening hybrids of cabbage. ResultsThe degree of susceptibility of hybrids to tobacco thrips varied significantly during the three years of research, but there were distinguished lines that established themselves as the most stable: Yas25p, Ts139, Agrbh82, Pi 714, 272Br-22. Hybrid combinations with these lines showed the least loss of marketable yield and the minimum number of affected leaves in each year of the study. Of the zoned hybrids, the Revansh F1 hybrid shows a high tolerance. It was found that a later planting period significantly reduces the degree of thrips damage.

Relevance Fermentation of vegetables is usually carried out in the traditional way (spontaneous fermentation using native microflora), but the quality of the finished product is difficult to predict. Very often, due to the low initial amount of lactic acid bacteria or their low activity, the result of the process remains unpredictable, which can lead to the loss of a significant amount of product. In the fermentation of vegetables involved several types of facultatively anaerobic lactic acid bacteria. In order to control the fermentation process and make it directed, it is necessary to study which lactic acid bacteria are involved in the fermentation process, the period in which their growth and death, and how it affects the organoleptic properties of the finished product, as well as to study the activity of lactic acid microorganisms in the fermentation process. When fermentation of vegetables are not only the original nutrients such as vitamin C, amino acids, dietary fibers, etc., but also develop functional microorganisms such as lactic acid bacteria. Fermentation has an important effect on the quality and taste, so it is very important to study the fermentation process, microbial diversity and changes in nutrients and chemical elements in the fermentation process. Reducing the rate or preventing microbial spoilage of food is based on four main principles: minimization of product contamination by microorganisms; suppression of growth and reproduction of microorganisms-contaminants; destruction of microorganisms-contaminants; removal of microorganisms-contaminants. Fermentation is based on a combination of the first three principles and is achieved by creating conditions for the growth of specific microorganisms that can give food the desired taste, aroma, texture and appearance. Results This review is devoted to the scientific aspects of vegetable fermentation, including crops that contribute to the creation of optimal conditions for the development of the main pool of lactic acid microorganisms, the production of finished products of high quality and the prevention of microbial spoilage. It is shown that at the first stage of fermentation lactobacilli of the genus L. mesenteroides play a determining role. It is their "work" to create optimal conditions for the development of the target lactic microflora depends on the quality of the finished product. This fact should be taken into account when creating industrial bacterial starter cultures – "starter cultures" for the directed process of fermentation of vegetables.

Relevance. Currently, there is an interest in this country in vegetable varieties of Vigna unguiculata subsp. sesquipedalis (L.) Verdc. However, a small number of varieties adapted to different cultivation conditions prevents a wider distribution of this crop. The present work was aimed at creating new vegetable cowpea varieties adapted to the climatic conditions of southern regions of Russia.Materials and methods. The study was carried out in 1998-2018 in the Astrakhan Province (Astrakhan Experiment Station) and in 2012-2018 in Primorsky Territory (Far East Experiment Station). Vegetable cowpea accessions from the global VIR collection were studied.Results. Many years of breeding have resulted in creation of such varieties as ‘Astrakhanskaya krasavitsa’, ‘Kaspiyskaya zarya’, ‘Zhemchyuzhina Kaspiya’ and ‘Lyanchihe’, which were included in the State Register of Breeding Achievements in 2019. All varieties are characterized by earliness, high productivity, excellent quality of vegetable pods, high protein content in pods in the technical ripeness phase (29.5-33.5%), and by low demand to the soil fertility. ‘Zhemchyuzhina Kaspiya’, ‘Astrakhanskaya krasavitsa’ and ‘Kaspiyskaya zarya’ are tolerant to high temperatures, air drought and soil salinity. The growing season for these varieties lasts 62-68 days in the Astrakhan Province under irrigation, while technical ripeness of pods occurs in 46-50 days. The green pod yield is 16.1–28.2 t/ha and the seed yield is 1.91-2.71 t/ha. The ‘Lyanchihe’ variety tolerates humidity well; its growing season in southern Primorsky Territory is 97-110 days, and pods reach technical ripeness in 61-70 days. The green pod yield is 21.0-24.0 t/ha, and that of seeds is 2.38-2.64 t/ha. The released varieties will broaden the range of vegetable crops cultivated in this country and improve the quality of nutrition of the population.

Relevance. Widely used traditional wine varieties of European-Asian grapes are characterized by a low level of resistance to disease and require multiple treatments with pesticides to preserve the crop and plants. Obtaining and introduction of sustainable varieties into production is one of the urgent problems of modern viticulture in the world and in our country, especially in the aspect of the ever wider dissemination of the principles of organic production. This is especially true for vineyards located in the coastal areas of the South of Russia, where the use of methods of chemical protection of vineyards from pests and diseases are limited to the proximity to the sea coast and the status of the resort region.Material and methods. The paper presents the results of the study of white wine grapes of the new generation with a high potential for resistance to environmental conditions and diseases. Purpose: research and development of recommendations on the use of white wine grapes of the new generation, characterized by resistance to adverse environmental conditions.Results. It is revealed that the experimental white wine varieties are characterized by a high level of adaptive capacity. In terms of productivity, new varieties are not inferior to the Sauvignon variety. Wine materials made from new resistant varieties are characterized by a high content of extractive and phenolic compounds. According to the organoleptic characteristics of wine materials from new resistant white grape varieties are at the level of the control variety. It is established that the level of stability of new grape varieties can be excluded from the technology of care of the vineyard measures to protect against major diseases, which significantly reduces the cost of production and allows you to get environmentally safe and organic products.

Relevance. Potatoes with red and purple flesh are highly valued dietary products and sources of polyphenolic compounds with antioxidant activity, especially anthocyanins. It has been found that the anthocyanin content in potatoes correlates with the total soluble phenolic content and antioxidant activity. These measures are significantly higher for coloured potatoes. The total phenolic content in particular the total anthocyanin content increases during the cold storage of coloured potatoes. Pigmented potatoes are also more preferable for food and industrial processing because of retaining of antioxidant properties and improving of final products quality. Сoloured potatoes selection and biotechnological approaches of regulation of anthocyanins accumulation are based on the understanding of the molecular genetic processes of anthocyanins biosynthesis. The anthocyanin biosynthesis is a part of the phenylpropanoid metabolic pathway. It is controlled by the MBW complex. The MBW complex includes the transcription factors MYB, bHLH, and WD40. A number of the MYB complex genes have been identified in potatoes. The key role in potatoes pigmentation variability is currently assigned to the StAN1 gene. According to available data anthocyanins play a protective role in response to various types of stress in potatoes.

Relevance The relevance of the bioenergy assessment follows from the requirements of modern production: energy saving per unit of output. Methods The article presents the data of bioenergy evaluation of the use of table predecessors, types of fertilizers and growth regulators in the technology of watermelon cultivation. Results The results of studies have shown that from the energy point of view, the proposed methods of cultivation of watermelon, are effective, because the coefficient of energy efficiency in all the studied variants is more than one. Studies have revealed the advantage of a layer of perennial grasses as a precursor to watermelon: CEE – 2.55 at its values according to the predecessor of winter rye – 1.70. The use of mineral fertilizers dose N60P90K60 in rain conditions leads to a significant increase in energy consumption of commercial products, 1.7 times more in the formation of perennial grasses and 1.3 times more than the predecessor of winter rye. A decrease in the CEE and an increase in the cost of total energy and energy intensity of 1 ton of products using manure 27 t / ha in relation to mineral fertilizers. Comparative energy analysis showed high efficiency of using water-soluble fertilizers and growth regulators for soaking seeds and processing of vegetating plants in watermelon cultivation. The use of these agricultural practices can reduce the energy costs of total energy by 70-79% compared with the introduction of mineral fertilizers dose N60P90K60, with an increase in the energy efficiency coefficient from 1.54 to 2.68-2.77. As shown by calculations from the energy point of view, the best was the reception of cultivation of watermelon table using for seed soaking and processing plants in vegetation water-soluble fertilizer master special with the addition of growth regulator megapol, the value of the EPS was amounted to 2.99, which is 7.9% and 11.5% more in comparison with potassium Humate and Ribav-extra, respectively.

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.
