One of the main directions of onion crops breeding in the world is heterosis breeding. Heterosis hybrids occupy the main place in the commodity production of onions in the Netherlands, USA, Japan and other countries. In State Register for Selection Achievements Admitted for Usage (National List) of the Russian Federation, admitted to use in 2018, made 378 cultivar of onions, including 188 (49.7%) – F1 hybrids, of which 140 – foreign breeding. A common way to create heterosis hybrids F1 onions is the use of lines with cytoplasmic male sterility (CMS) as one of the parent forms. The article presents the results of multi-year research of the laboratory of breeding and seed production of onion cultures (VNIISSOK, now FSBSI FSVC) to assess and highlight the lines of CMS onions with high combinational ability, the creation of heterosis hybrids on their basis. In 2002-2005, 229 cultivar of onion were studied to identify plants with pollen sterility and maintainer. 515 plants with CMS were isolated. In the subsequent years (2006-2010) was established 1588 maternal lines (S msms) and the fathers of maintainer (N msms). To obtain F1 hybrids with the maximum level of heterosis, the combined ability of lines and pollinators was evaluated by topcross and diallel crosses. The best lines for the complex of economically useful features with high combinational ability were included in various combinations of crosses with inbred lines in order to select high-performance hybrid combinations and to create F1 hybrids. 547 combinations of crosses of sterile lines with inbred paternal lines were carried out, on the basis of which 408 F1 hybrids were created. After testing and evaluation of them in the hybrid and breeding nurseries allocated 23. According to the results of the competitive test samples were identified, which under the names of Logran F1, Zarnitsa F1 and Solnyshko F1 transferred to the state variety test.

Leek very ancient culture which was widely applied in cookery and as remedy still by ancient Egyptians, Greeks and Romans. Now the leek is widespread in countries of Western Europe and North Africa, in the USA, Canada, Australia. On chemical composition it is one of the most valuable onions representing in fact "the alive table of Mendeleyev". In such countries as Belgium, Holland and France it is one of the main vegetable cultures, and annual production it per capita makes from 4 to 10 kg. In Russia, unfortunately, it is still rare culture though falls into to the most valuable types of an onion on biochemical structure, productivity, resistance to wreckers and diseases. Widespread introduction of a leek in production restrains a number of factors among which lack of early ripening varieties with the increased resistance to extreme environmental conditions, and in this regard – difficulty of receiving high-quality seeds of leek in a midland of Russia to the north of Rostov-on-Don. Therefore, a vital necessity is on the basis of study under various conditions of cooperation a "genotype is an environment" and selection from world collection of sources of economic-valuable signs, creation of productive sorts and hybrids with good resistance to cold, possessing in the conditions of Moscow Suburbs, along with the high productivity and quality of products, by a high adaptivity to the different terms of height winter spending. Results of long-term researches of laboratory of selection of onions cultures (VNIISSOK) on studying, assessment and selection of exemplars of grades of leek from the VIR world collection are presented in article, receiving hybrid combinations and lines, development of methods of selection and creation on this basis of grades and hybrids of leek for not seedling culture in a midland of Russia, possessing high rates of vegetable and seed efficiency, quality of production and winter hardiness.

Yaltinskiy onion is one of the symbols of the Crimea, the very name of which is tied to the famous resort, which emphasizes belonging to the Crimean Peninsula. Salad sweet onion is in constant demand among the guests of the peninsula and locals. Its price is several times higher than the price of other onion varieties. Unfortunately, under the guise of Yaltinskiy sortotype, products that are much inferior to it according to taste peculiarities are often sold. In this regard, creation of new cultivar of sweet salad onion, exceeding palatability of the existing cultivar Yaltinskiy Rubin is an urgent task, having an undeniable economic direction. The source material was collected at various zones of the Crimean Peninsula. During the research, hybridization and selection in hybrid progeny were carried out. The plants were analyzed using various methods of evaluation. Much attention was paid to biochemical analysis. The palatability traits are important for the onion cultivars of salad direction. The best indicators for sugars and vitamin C were identified in salad onion of a new cultivar Yaltinskiy plus. Reducing the content of essential oil has improved the taste and its consumer properties. Useful properties were also supplemented by the fact that the presence of selenium antioxidant 68 μg/kg and anthocyanins of 1.66 mg/100 g in salad onions was established, which is 1.5 and 2.3 times higher than the standard sample showed. The content of quercetin and other polyphenols was also noted. The cultivar is characterized by high agronomic stability (90%), product quality (88%), and productivity (49 tons per ha).

The excretion and inculcation of stamped varieties of tomato and hybrids into production are of particular value in conditions of dry subtropics. In this regard, during 2013-2015 in the Surkhandarya Scientific Experimental Station of the Research Institute of Vegetable and Melon Crops and Potatoes, a collection of tomato strains was studied for biological and economic precocity, maturity, etc. For the duration of the «young growthflowering» period, the best were No.86, Yamal, GemState, and Sever. Blooming on the first brush, they come in 8-13 days before the standard variety. The Argo, Chelnyok, Ion-N, Alpatyeva 905а, L-923-92 samples with a duration of 38-40 days have a short period of «flowering-ripening». Maturation of the first fruit (fetus) occurs 1-3 days earlier than the standard. By weight of the fetus, the samples studied can be divided into two groups: medium fruit (61-93 g) – L-923-92, Argo; small fruit (28-58 g) – GemState, Ion-N, Sever, Nevsky, etc., only 10 samples. The total yield varies from 16.4 to 55.5 t/ha, depending on the variety. Samples No.86 and Chelnok are 7.7 and 12.3% higher than the standard for the general harvest. The lowest overall yield is GemState, Ion-N, Sever, Nevsky, Yamal, Argo, L-923-2, with a yield of 16.4-34.1 t/ha, which is 33.2- 69.0% of the standard. The only sample No.86 for the early harvest is 32% higher than the standard. As a result of the study and a comprehensive assessment of tomato stamping varieties, the biologically early ripened ones are Sever, Nevsky, Ion-N, Otradny, GemState, the sprouting-maturing period of which is 95-99 days; economically early ripened – No.86; amity of ripening of samples – Yamal, Sever, Ion-N, Nevsky, Stamped Alpatyeva 905a, GemState, with maturity ripeness from 69 to 90%. They are a valuable source material for selection of stamped, early-ripening, amity of ripening varieties of tomato for dry subtropics conditions of Uzbekistan.

A methodology for analyzing the agricultural market has been proposed. The concept of the market model from the standpoint of the dynamic equilibrium of supply and demand is described, a technique based on variational deviations of trends is proposed. Approbation shows the practical usefulness of the results obtained in the analysis and management of the cabbage market. The interrelation between the gross volume and the price of cabbage is established, the gradient and nature of market equilibrium are revealed, and the perspective of the cabbage market in the Russian Federation is described. The proposed analysis methodology considers market modeling as a dynamic equilibrium mechanism of supply and demand, it is a method based on variational deviations of trends. Approbation confirms the practical utility of the results for analyzing and managing the cabbage market. In the course of testing, it was established that the amplitude of price fluctuations with the current increase in gross production characterizes the cabbage market as developing; the market offer of each thousand tons of cabbage can change the price by 0.1416 c.u./t; the cabbage market maximum is at the level of 258 c.u./t at gross harvest of 3,138 thousand tons of cabbage. For the modern stage of development of the cabbage market with increasing production volumes, a decrease in prices is typical. It is shown that there are market relations between gross volume and price of cabbage, market characteristics and equilibrium gradient, which determine the prospects of the Russian cabbage market. The description of the methodology and the presentation of the results of testing the methods of modeling the market perspectives allow us to make optimistic conclusions about the expansion of the scope of application of theoretical economics for practical activities. In this regard, the proposed methodology for analyzing the market (concept, methodology) may be of interest to practicing economists. Despite the simplicity and accessibility of the described methodology, there are a number of issues related to the error of statistical data and unaccounted factors that require further research.

Supply of the domestic fresh vegetables commodity to the population of Northern regions of Russia is one of the most priority tasks of the national economy. Lack of the local, high-quality and adopted breeding material is highly problematic for breeding programs. Generation of the new, highly productive vegetable cultivars for the glass-covered ground, including light culture, will promote to expand significantly the volume of local production of vegetables in protected ground, especially in regions with a cold climate. One of the most prospective crops for protected ground is small radish, an early ripening crop with a valuable biochemical composition. А strategy for creation of the new, highly productive forms of small radish, beard predictable complex of economically valuable characters for growing in conditions of intensive light culture, has been developed in the Agrophysical Research Institute (SaintPetersburg). At the first stage, represent interspecific set of 26 small radish cultivars from different regions, was investigated in controlled conditions (artificial light, climate cell) to reveal a complex of economically valuable properties (early maturity, productivity, morphological traits). The plants were grown in original plant grooving light equipment (lamps DNaZ-400, photoperiod 12 hours, irradiation 15-20 klk), in a small volume of substrate (peat with mineral additives). It was observed that the small radish varieties have significant diversity in precocity, productivity, resistance to bolting, also they vary in a number of morphological features of roots and leaves. Bov, Estella, Rocco (Netherlands), Nobo Chind Criollo (Peru) were the most productive cultivars. They can produce yield of commercial roots during 30 days of vegetation up to 3.5 kg/m2. In addition, cultivars – genetic resources of economically valuable properties (compact rosette, glabrous leaf, resistance to bolting) were revealed for a breeding. Parent pairs for crossing were selected. It is planned to obtain offspring small radish forms with a complex of economically valuable properties, more productive than the parents. In all matched hybrid combinations, F1 hybrids were obtained. They have a degree of hybrid superiority in roots weight from 110 to 230% over the best of the parent form. They will become the ancestors of the original forms of small radish, intended for cultivation in conditions of intense light culture.

Evaluation of biochemical characteristics of 8 perennial Allium species is achieved (A. ramosum, A. caeruleum, A. erubescens, A. obliquum, A. moly, A. aflatunense, A. oreophilum and A.ursinum). High nutritional significance of separate decorative species is demonstrated. A. caeruleum is shown to be a leader in the accumulation of ascorbic acid (more than 9000 mg/100 g d.w.) and polyphenols (more than 8000 mg GAE/kg d.v.). Detected ascorbic acid concentration range for 8 studies Allium species was 568 (A. ramosum) – 9980 (A. caerulum) mg/100 g d.w.; polyphenols 1392 (A. obliquum) – 8582 (A. caerulum) mg GAE/kg d.w.; water-soluble compounds 28 (A. aflatunense, A. obliguum) – 69 (A. ramosum) mg/kg d.w.; chlorophyll 0.54 (A.oreophilum) – 1.69 (A. ursinum) mg/100 g d.w.; carotene 0.07 (A. oreophilum) – 0.25 (A.ursinum) mg/100 g d.w.; selenium 72 (A. ursinum) – 245 μg/kg d.w., (A. ramosum). Adequate consumption level of vitamin C may be provides by 6.2 g of A.caerulum leaves. Antioxidant activity of Allium species alcoholic extracts composed a range from 1.5 (A. obliquum) to 6.4 (A. ursinum) mg GAE/g d.w. A. ramosum and A. oreophilum demonstrated the highest content of total soluble solids. The highest content of photosynthetic pigments happened to be typical for A. ursinum. The ratio between antioxidant activity of alcoholic and water extracts of Allium leaves was in the range between 0.89 and 2.21 depending on plant species: the highest value was registered in leaves of A. ursinum, the lowest – in leaves of A. ramosum. In a whole the highest content of antioxidants was demonstrated for leaves of A. caerulum. The highest levels of photosynthetic pigments and antioxidant activity of alcoholic extracts were indicated in leaves of A. ursinum.

One of the most important crops among all types of Alliums is onion, the value of which is determined by the nutritional and medicinal properties. It is used not only as a seasoning for food, but also as a source of a number of biologically active substances. The biochemical composition of the bulbs and its green leaves in different periods of growth and development varies, depending on the variety, environmental conditions and agrotechnical methods of cultivation. Creation on the basis of interspecies hybridization of fundamentally new forms of Allium plants with a unique combination of genetic material allows to expand the possibility of selection of valuable genotypes in practical terms. The study was performed on plants of the inbred progenies I4-5 from BC1-2 bulbous forms of interspecific hybrids of Allium crossing combinations F5(A. cepa xA. vavilovii), F5(A. cepa x A. fistulosum). The biometric assessment was carried out after harvesting and drying the bulbs according to the "test Procedure for distinctiveness, uniformity and stability" according to the main breeding characteristics: the color of the dry cover scales of the bulb, the mass of the bulb, the shape of the bulb. As the standard used plant varieties Odintsovets. The biochemical composition of onion samples was determined by the content of dry matter, monosaccharides, the amount of sugars, ascorbic acid, antioxidants. Based on the biometric assessment of the forms of interspecific hybrids of onions, 5 forms were identified according to the uniformity of such features as the color of dry cover scales and the shape of the bulb weighing 50-60 g, which are a qualitatively new source material for breeding. In determining the biochemical composition of the isolated forms of interspecific hybrids of Alliums on the main breeding grounds found that the plants of these forms of onions indicators of dry matter (15%), monosaccharides (1.15-1.71%), the amount of sugars (11.17%), were at the level of the standard, or exceeded it, but the total content of antioxidants (8.22 mg/g) inferior to the standard.

Along with heat treatment, Smoking and drying in the sun, one of the oldest ways to preserve food is fermentation (fermentation). Fermented foods appeared long before people learned about the existence of microorganisms, and entered the traditional diet of almost all cultures. Currently, the production of salted, fermented and wetted products is an important segment of the food industry. The rate of reproduction of microorganisms in foods is affected by several factors including properties of the products (nutrient content, pH value, oxidation-reduction (redox) potential, water activity, etc.) and external factors, including storage conditions, such as temperature and relative humidity. Preservation of food products is usually based on the destruction of microorganisms or control of their reproduction and the overall composition of the microbiota. Reducing the rate or preventing microbiological spoilage of food is based on four main principles: minimization of product contamination by microorganisms; suppression of growth and reproduction of micro-organisms-contaminants; destruction of micro-organisms-contaminants; removal of micro-organisms-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. This review is devoted to the scientific aspects of vegetable fermentation, including the use of bacterial starter cultures. The characteristics of lactic acid microorganisms are given, the basic principles and advantages of the process of fermentation of vegetables and the biochemical processes taking place at the same time are given and described, the advantages of the use of bacterial starter cultures (strains of lactic acid microorganisms) for the purpose of improving the quality of the finished product are described.

Growing heterotic hybrids of cucumber on large areas is possible only if the production of their seeds does not require large additional labor costs in comparison with conventional varieties. Cleaning of maternal forms by flowering type – removal of plants of intermediate type of flowering and single male flowers on plants of predominantly female type requires considerable labor costs. Significantly simplifies and reduces the cost of hybrid seed production using maternal forms of female type that do not have male flowers. It is very important to create maternal forms with a consistently high female expression that do not respond to changing environmental conditions. This will allow hybrid seed production of cucumber not only in protected, but also in the open ground, which will significantly reduce the cost of production of seeds. The objective was to assess the maternal forms of the cucumber hybrids F1 Krepish (L-100), F1 Brunet (L-105), F1 Frant (L-290), F1 Krasotka (L-25) according to the female expression in the conditions of spring film greenhouses and open ground near Moscow. The open ground served as a provocative background for identifying the most stable in terms of the severity of the female sex lines. It was determined that the bee-polluted hybrids of the cucumber F1 Krepish and F1 Brunet are most suitable for conducting hybrid seed production in the open field, since their maternal forms need to be cleaned according to the blooming type less than others.
