On the 21th September of 2018 Pivovarov Victor Fedorovich – scientific adviser of the Federal Scientific Vegetable Center, Academician of Russian Academy of Sciences, Honored Scientist of Russian Federation, State Laureate of Science and Technology, Doctor of Agricultural Science, Professor, is celebrating 50 years of his scientific and pedagogical activity. Dr. Pivovarov V.F. is the leading scientist in the field of ecology, introduction, horticulture, breeding and seed production of vegetable crops. Since having been appointed to a director of VNIISSOK, V.F. Pivovarov has continued to keep up the best traditions of Russian plant breeding school. By now, the VNIISSOK has become a scientific and methodical center for vegetable plant breeding and seed production, where many theoretical studies, the advanced technologies and methods of development of initial breeding material of vegetable plants for further breeding programs are carried out.

The vegetable production is one of the main factors for food security, as vegetables play an important role in the structure of nutrition. The Federal Scientific Vegetable Center creates competitive varieties and hybrids of vegetable crops that meet market requirements to meet the needs of domestic producers and thereby contributes to food security. As a result of national breeding program, the varieties and hybrids adapted to different growing conditions, with resistance to local races of pathogens, temperature stresses, and ground frosts were developed to provide the sustainable production of vegetables with high nutritional and medicinal qualities. The varieties and hybrids F1 of white head cabbage that have been created for the last 5 years are distinguished from foreign ones by taste qualities, appropriate pickling characteristics with increased sugar, and decreased cellulose contents. The local onion varieties combine long shelf life, early maturing, well bulb formation, high dry matter content (18-20%) and ability to form the bulb for one year. Breeders have developed bee-pollinated and parthenocarpic hybrids of cucumber well adapted to local growing conditions and suitable for open field cultivation in different regions of Russia. Parthenocarpic heterotic hybrids of the multi-propose use, corresponding to the modern variety model with high productivity, early-ripening, bunch ovary disposition, resistance to abiotic stresses, and most harmful diseases. The carrot and red beet varieties with high nutritional qualities, long shelf-life, ecological plasticity that are widely used for seed production have been created. The varieties of Solanaceae crops have been developed to cultivate in Non Chernozem zone, Far East, Western Siberia, the Middle Belt of Russia and the south of Russia, are also suitable for different greenhouse complexes located in different light zones of the Russia. Wide application of varieties produced through national vegetable breeding programs can provide the population with our own products of high quality.

It is important to reveal the genetic base of breeding genetic material used for development of new breeding accessions among diverse Brassica oleracea L. (CC, 2n = 18). Traditional varieties, hybrids and new ones recently developed are the main genetic resources.
Classification of a collection with DNA markers enables to reveal valuable genotypes and establish the breeding accession pedigree that allows developing the new accessions with sustainable economically valuable traits. The use of microsatellite markers (SSR) in B.oleracea L. has shown high efficiency in discovering genetic polymorphism between varieties and within varieties as well. In this study, 16 primer pairs have been taken to amplify microsatellite loci of genomic DNA in national 24 breeding accessions of cabbage. On the basis of the data obtained the dendrogram has been constructed with use of Jaccard’s coefficient. All locistudied were high informative, where 14 out of 16 had a PIC > 0.5. As a result, the level of genetic polymorphism has reached 85.7%. The large cluster of head cabbages consists of three subclusters: mid-maturing and early-maturing accessions of white head cabbage, red head and savoy cabbages, late-maturing and midmaturing accessions of white head cabbage, respectively. Maximum genetic distance in the cluster of head cabbages was obtained between head cabbage ‘Slava 231’ and ‘Vertu 1340’ with genetic similarity 44.7%. The two varieties of red head cabbage ‘Gako 741’ and ‘Kamennaya Golovka 447’ were genetically similar at 71.1%. The relatively low genetic similarity of these varieties can be explained by that they belong to different varietal groups. The most genetically closest varieties were ‘Zimovka 1474’ and ‘Podarok‘ with genetic similarity 86,5%. Information on topologic differentiation obtained from cluster analysis can be the basis for selection of genetically valuable breeding material with the use of DNA markers (Marker Assisted Selection).

The culture of unpollinated ovules in vitro in summer squash was used to develop fully homozygous breeding lines with the aim of the speeding-up breeding program. As a result of assessment for economically valuable traits, the seven promising DH-lines obtained from summer squash accessions differed by fruit shapes and colours were selected out. All breeding lines produced showed high homogeneity that retained in following generations and also have an appropriate set of economically valuable traits. DH-lines belonging to female type have up to 96% female flowers and only 4% male flowers. It is very important for breeding when the male flowers appeared in two weeks just after the female flower began blooming. The development of morphologically abnormal female and male flowers, along with gynandromorphy flowers was noted on selected DH-lines. During vegetation period from 26 to 36 flowers appeared on the plant, where out of them 19-21 ones were normally developed female flowers, 3-5 ones were normally developed male flowers, and up to 10-11 ones showed an abnormal way of development. The percentage of abnormal flowers stayed invariable when growing in greenhouse condition with high humidity and temperature as well as in open field condition. As it was shown the development of deformed abnormal flowers inherited and manifested in the following generation after self-pollination. As a result of the study, the occurred anomalies in course of male and female flower development in summer squash (C. pepo L.,) DH-lines produced through a cultivation of unpollinated ovules in vitro were described in details for the first time.

In breeding programs agriculture, interspecies hybridization is an important tool for creating a genetically updated source material in the breeding of varieties. The material consisted of perennial plants of interspecific hybrids of onions BC2(F3-5(A. cepa x A. fistulosum)), BC1(F1-5(A. cepa x A. vavilovii)), F5(A. cepa x A. altaicum) and their inbred offspring. As standard on biometrics and the susceptibility of plants with downy mildew used a variety of onion Odintsovets, as this grade participated in the conduct of the saturating crosses of onion and perennial species A. fistulosum L., A. altaicum Pall. Field experiments were carried out according to the standard technique in conditions of the Moscow region at the experimental base of FSBSI FSVC. Based on the results of the research highlighted in the form of combinations of the cross A. cepa x A. vavilovii and A. cepa x A. fistulosum and A. cepa x A. altaicum interest to breeding in number of leaves, length of leaves, number of seedstalks, the height of the seedstalks, high fertility and relatively high resistance to Peronospora destructor. Forms combination of the cross A. cepa x A. vavilovii was characterized by uniformity the number of seedstalks (5-7 PCs), the height of the seedstalks (96 cm) and resistance to downy mildew (1.0-1.5 score). Forms combination of the cross A. cepa x A. fistulosum stood uniformity by the number of seedstalks (5 PCs), the height of the seedstalks (85-96 cm), resistance to downy mildew (1.0-1.5 score) and a high fertility rate (over 60%). On the basis of the company "regrowth – mass setting of seeds" in each combination of mating types was allocated a separate form, which was distinguished by precocity: BC1(F5(A. cepa x A. vavilovii)) (86 days), BC2(F5(A. cepa x A. fistulosum)) (63 days), I1F5(A. cepa x A. altaicum) (61 days).

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.

The variability or stability of economically valuable features of varieties under cultivation conditions are very important indices. Environmental factors affect plants throughout the entire growing season. The research goal is to study the changes and stabilization of the characters that determine the phenotype of winter garlic when sampling from the variety accessions in the forest-steppe of the Altai Regions' Ob River Area. In the course of research from 2003 through 2007, the local forms and variety accessions from various regions of Russia were studied. The research was carried out according to the methodology guidelines. The variability of seven quantitative characters was investigated. In our study, the most stable characters were the "number of leaves" and "leaf length". The characters "number of cloves in a bulb" and "clove weight" are very difficult to stabilize. The variability of these indices was mainly medium and high. The characters with insignificant variability coefficient under the conditions of the south of West Siberia were revealed. The percentage of the factors' influence on the variability of the "bulb weight" character was determined. The following most stable variety accessions for the conditions of the forest-steppe of the Altai Regions' Ob River Area were identified: the varieties Skif, Kasmala and German, and the local forms K 3 and K 56.

Garlic is one of the most ancient plants which the person turned to himself on advantage. The larger need for production of garlic for consumption and as raw materials for manufacture of medicinal preparations and, at last, just for use by the population as remedy for many diseases and for the preventive purposes led to the fact that bulk production of garlic in the world makes 24,836 million tons, and the area under garlic reached 1,465 million hectares. n Russia the area under garlic on all categories of farms is 28,4 thousand hectares, and production – 256,406 thousand tons. From factors influencing on the increase production of garlic, one of basic is a sort. Selection of garlic includes improvement of local grades, creation new high-yield, steady against diseases and to wreckers of grades, with the increased content of sugars, essential oils and biologically the active materials. Results of long-term researches by laboratory selection of onions cultures (VNIISSOK) on studying, assessment and selection exemplars grades of garlic winter, collected from different regions of Russia and the CIS countries, on a complex of signs are presented in article (winter hardiness, efficiency, to quality of production, resistance to wreckers and diseases).

The basis for increasing the production of vegetables and melons is to obtain high-quality seeds of high reproductions. This will ensure the implementation and stability of breeding characteristics of varieties, the preservation of economic and valuable features. To solve these tasks, it is necessary to transfer the industry to a new, more modern level of seed production. The studies were conducted using the methods of individual and individual-family selection with evaluation by offspring, using the method of "halves" through control and elite nurseries. The method of production of elite and original seeds is developed. Conducted research to improve schemes of sowing of gourds with the study of the influence of space power to approbation the signs of varieties with different index of fruits. By reduction of the nutrition area per plant to 2.1 sq m2 in the variety of watermelon Icarus the yield of seeds increased 1.5-1.9 times in comparison with the standard number of fruits with an index of <1.0 was 8.2%. The thickening of the crop did not have a noticeable effect on the shape of the fruit. A watermelon with a broadly elliptical shape of the fruit, variety Volzhanin observed dependence of the shape of the fruit from planting schemes. With the reduction of the nutrition area up to 2.1 m2 number of fetuses with index >1.5 28.2% in the second generation, the seed yield was 111.9 kg/ha. The change in the index of the foetus has led to a significant change in varietal characteristics, which is unacceptable in the primary seed production. Reducing the area of nutrition in watermelon varieties with spherical and rounded shape allowed to increase the yield of seeds without affecting the varietal characteristics.

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.

As part of working on the solution of the task of importing asparagus beans, it is necessary to create a conveyor of green beans for vegetables during the growing season under the conditions of the Central Nonchernozem Zone (CNZ). In this regard, in 2018, work was continued on the evaluation of the existing collection of the FSBSI FSVC on economically valuable grounds, which allowed pre-select promising samples for further breeding work. According to the results of the assessment of the collection variety samples of vegetable beans in 2018, 30 variety samples of different groups of ripeness were identified as initial forms for breeding work on creating varieties that meet the requirements of the processing industry and creating a conveyor for producing asparagus products in the CNZ. Selected varieties are described and evaluated for the productivity of beans and seeds, suitability for mechanized harvesting, quality of the bean, seed size, resistance to the most harmful diseases. It is important to note that the year 2018 was unfavorable for the optimal development of culture due to the negative weather conditions that developed from the 3rd decade of May to the 2nd decade of June. This has made its own adjustments to the development of plants, as a result of which the assessment on some grounds is not indicative.

The historical reference of Asparagus officinalis (Asparagus officinalis L.), its species composition and practical use is given. Biological and agrotechnical features of culture, the most common diseases and pests are presented. Grades and methods of selection work. Sexual type of asparagus, perennial varieties and the ability of plants to vegetative propagation are important factors in asparagus breeding. The following methods are used in asparagus selection: hybridization; formation of male varieties via self-pollination of bisexual flowers found on male plants; utilization of the heterosis effect the formation of homozygous inbred-lines; production of tetraploid forms by exposure of colchicine to asparagus seedlings. Selection can be done either on individual plants or using multiple approach. Improvement of selection may be achieved using several parameters: plant yield, the mass of seedlings; plant height of the most developed shoot; the number of shoots. This allows to discard undesirable forms at early stages. Laboratory of green vegetables, spicy-flavoring and flower crops of the Federal Scientific Vegetable Center possesses the collection nursery of 7 samples of Asparagus officinalis: K-25, K-28, K-41, K-46, Mary Washington Bruswick, Paradise. The latter are used for Asparagus selection with the aim to retain economically valuable traits.

Shallot is one of the most popular onion crops at present. This is a multi-purpose crop in terms of possible use of its economically valuable features. In order to realize the potential of this crop, its varieties are needed. The work on the development of varieties adapted to the conditions of the south of West Siberia was carried out by the plant breeders of the West Siberian Vegetable Experimental Station from 1999 through 2018. The research goal was to study introduced and local forms of shallot variety accessions and to obtain varieties adapted to the conditions of Siberia with high indices of economically valuable features. In 1999, the plant breeders began working with the collection of shallot hybrid material obtained by polycross method at the Siberian Research Institute of Crop Production and Plant Breeding. Shallot variety accessions introduced in different climatic zones (Far East, Kazakhstan, Krasnodar, the Urals, Siberia, Non-Chernozem Zone and Holland) were used as initial forms for hybridization. Five variety accessions were obtained; they successfully underwent the State Variety Testing and were released.

In terms of occupied areas, onion is on the third place in the world among vegetable crops, second only to tomato and watermelon. In Russia, onion is grown on an area of 88 to 96 thousand hectares of onions, and ranks third, yielding to cabbage and tomato.
The increase in the production of onions is not only due to the increase in the areas occupied by the crop, but also due to increased yields. This is achieved by introducing new highly productive varieties and hybrids into production, increasing the overall cropping culture and the level of cultivation technology. Along with the creation of heterotic hybrids at the present time, the Russian Federation also continues to select varieties that show high rates when grown in a oneyear crop. The results of production tests of a new onion variety of Forward Selected Breeding VNIIO a branch of the FGBNU FNCO has shown that it is promising because it has a high yield potential, high quality of bulbs and excellent preservation in conditions of repositories with controlled conditions. Characterized by mid-maturity maturation. The period from full shoots to mass lodging of leaves is 110 days. In relation to the longitude of the day, the forward sort refers to a group of long-day bows. The bulb is bilobate, rounded and rounded – flat, with an average mass of 90-120 g. The color of the dry covering scales is yellow-brown, the succulent scales are greenish. The taste is semi-sharp. The dry matter content in the bulb during the test years was 11.0-12.0%.

One of valuable spice-aromatic vegetable of Lamiaceae family is lemony monarda (Monarda citriodora L.) cultivated as nonperennial crop in most of regions of Russian Federation. Information regarding its parentage and biological special aspects are described here in this article. Brief review regarding nutritional quality and pharmaceutical importance as well as description of four cultivars of lemony monarda (which are currently included to Russian State register of selection invention and approved for usage, two of these cultivars Mona Lisa and Simka were selected and cultivated by Federal Scientific Vegetable Center are given here in this article. Main directions for up-to-date selection and application and practical usage of lemony monarda were indicated. In the field of creation of up-to-date vegetable cultivars, one of the main directions is selection of such a cultivars with high content of biologically active compounds for improvement of antioxidative activity and applicability for its cultivation at hydroponic plant with frame area to provide fresh green vegetables for people all year round. Simka cultivar meets requirements mentioned above and can be cultivated at various types of hydroponic plants including horizontal (salad lines, seedling tables) and vertical (multilayer hydroponics) types using natural (drag turf) or artificial (mineral wool blocks) substrates. This article also describes the main elements of technology of cultivation of lemony monarda in the open and protected ground to get green products and seed production. The features of the preparation of raw materials with a high content of biologically active compounds for fresh consumption and as a spicy-aromatic dry seasoning for salads, meat dishes, as a natural preservative and aromatic of jam, tea and other drinks are shown.

Lemon monarda (Monarda citriodora L.) is a decorative, spicy taste and a vegetable of the family Lamiaceae. In Russia it is grown as a spicy-aromatic and medicinal plant. It is also called lemon bergamot, lemon mint, lemon bee balm, as the leaves, stems and inflorescences have a strong smell of lemon. Monarda is often used as an additional ingredient in the preparation of various dishes. During the development of the standard "lemon monarda (greenery). Technical conditions", the basis of the data received by the laboratories of the Federal Scientific Vegetable Center: green, spicy taste and floral crops; standardization, regulation and Metrology. The monarda standard includes the following sections: scope; regulatory references; terms, definitions and abbreviations; technical requirements; characteristics, packaging, labeling; rules of acceptance and sampling; test methods; transportation and storage; safety requirements.

Vegetable growing is one of the most dynamically developing branches of agriculture in the Russian Federation. Research on the economics and organization of the production of vegetables and fruits of melons and gourds began at the All-Russian Scientific Research Institute of Hydrometeorology (VNIIO) after its formation in 1930 and served as the basis for the creation of commercial vegetable-growing zones, specialized farms and green-house complexes around major cities and industrial centers of Russia, as well as vegetable farms in other republics. The following were developed: a promising scheme for the development and placement of vegetable growing in zones of the country in open and protected ground, scientifically based proposals for improving the organization and increasing the efficiency of vegetable growing in Moscow, Ryazan, Ivanovo, Bryansk, Irkutsk, Lipetsk and other regions of Russia. From 2000 to 2014, research focused on the development of concepts for the development of commercial vegetable and seed production of open and protected soil in the context of existing economic relations and forms of management. Since 2015, an analysis of the economic efficiency of vegetable production in the Russian Federation has been carried out, taking into account large-scale and small-scale production, interregional exchange of vegetable products, taking into account import and export, equivalence of inter-sectoral exchange, development of cooperation in the village, economic efficiency of long-term storage of fresh vegetables, and optimal size of vegetable production. for vegetable producers of all forms of ownership, safety of vegetable products in the context of food safety Russia. Today, Russia produces 105.7 kg of vegetables per capita per year, and in 2017, the self-sufficiency of open and protected soil in vegetables was 81.1%. The large stability of large-scale production was noted in the conditions of the unfavorable economic situation in the vegetable industry. Identified systemic problems that limit the increase in the production of vegetable products and adversely affect its effectiveness.

Amaranth leaves can be used in salads, soups, sauces enriching them with biologically active substances (in particular, ascorbic acid and phenolic compounds), as well as giving them an original taste and color. Plants were grown on the experimental field of VNIISSOK in the Moscow region. The experiment was laid on sod-podzolic soil. For the period of 2013-2016 years, biochemical parameters were investigated: total content of water-soluble antioxidants, ascorbic acid content, dry matter content, amarantine content in three amaranth varieties (Valentina, Don Pedro and Fakel) and two green leaf varieties (Pamyati Kovasa and Eku 17020) of FSBSI FSVC (formerly VNIISSOK) and INIAP selection and a correlation analysis was performed, which showed a relationship between the relative concentration of amarantine in the leaves and other biochemical parameters at different stages of plant development. The maximum accumulators of antioxidants according to the TAC parameter were the Valentina and Don Pedro varieties - up to 2.9 mg gallic acid equivalents/g. The situation was similar in terms of the content of the reduced form of ascorbic acid. So also the Valentina and Don Pedro varieties were leading with values of about 140 mg%. A positive correlation between the content of ascorbic acid and the sum of hydrophilic antioxidants was confirmed. Pamyati Kovasa and Eku 17020 varieties can be recommended as a source of green mass of leaves with a high content of ascorbic acid, red colored varieties Don Pedro, Valentina, Fakel – for obtaining red dye enriched with antioxidants.

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.

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.

In recent years, the demand for food has sharply increased in functional ingredients, especially in pectin. At present, there is no production of pectin substances in the Russian Federation, and the demand for them is satisfied, mainly due to the use of imported pectin. At the same time, the country has prerequisites for its own production of pectin from non-traditional types of raw materials, for example, bark of coniferous trees, which in the form of waste is produced in large quantities when processing wood in the timber, woodworking and pulp and paper industries, and goes to incineration, although its can be used to obtain such a valuable substance as pectin. The article considers the possibility of using pectins from the bark of coniferous trees in the production of fruit and vegetable nectars with pulp as a biological additive that improves the consistency of the product. To confirm this, VNII researchers of conservation technology conducted studies to test pectin from the bark of spruce and larch on their structure-forming ability. For this purpose, experimental samples of fruit and vegetable nectars with pulp were made: apricot, quince, cherry, redcod, plum and carrot, obtained on the basis of fruit and vegetable purees, as well as the calculated amount of sugar syrup with a certain concentration, with the addition of pectin from the spruce bark and larch, and for comparison samples with the addition of ordinary apple pectin. Pectin was added as a 10% solution in an amount of 9.0% of the total weight of nectar (in terms of dry pectin – 0.9%), which allowed to provide a homogeneous, non-dissolving consistency of nectars.

The article analyzes modern technologies for storing fruit and vegetable products and presents possible options for their modernization. From this perspective, the improvement of canning technology using non-traditional methods of processing plant raw materials is an urgent task, the solution of which will allow preserving fruit and vegetable products, reduce the amount of waste and reduce the impact of vegetable processing plants on natural water bodies. Fruits and vegetables are perishable products and require special storage conditions from the moment they are available for sale to purchase by consumers. Keeping them fresh for as long as possible is quite a challenge, as some plants are able to continue maturing even after packaging and produce ethylene, which initiates certain changes in texture and color, tissue degradation. The authors pay special attention to the aspects of innovative technologies in the creation of edible films and coatings, which are currently the only type of biodegradable polymer packaging that does not require individual collection and special conditions of disposal. This is their main difference from traditional biodegradable plastics, which were originally proposed as an alternative to synthetic polymeric materials, and all were convinced that their creation once and for all will solve the problem of waste polymer packaging, which today threatens to become a global environmental disaster. At the same time, they are always more expensive than conventional plastics, in many cases can not be subjected to joint recycling; being in the deep layers of the landfill, they emit greenhouse gas methane. In addition, the raw materials for biodegradable plastics are provided by the same soil and water resources on which food is grown today (except for a very small amount of plastics produced from agricultural waste), and therefore their raw material base will always be limited. Recommendations are formulated on the organization of effective conservation of plant raw materials, intended for further processing or sale in retail and wholesale trade networks.

The processes of fermentation, accompanied by the growth and development of several species of microorganisms, are often accompanied by a change of some species of microorganisms for anothers , such a complex "behavior" of microorganisms during fermentation needs to be be deeply researched. The previously used approaches of evaluation of the type of interaction of particulate monocultures in consortiums make it possible to obtain only qualitative results (synergistic, antagonistic, additive interaction) generally, without taking into the consideration the change of this interaction during the cultivation. The purpose of the research was the development of a new approach of the quantitative determination of the parameter of the interaction of microorganisms of one species with another species expressed as a continuous function determined throughout the all fermentation period. In the process of the work a two-component consortium of lactic acid microorganisms Lactobacillus brevis and Lactobacillus plantarum was selected, cultivated in two different model media as part of a study of directed fermentation of vegetable products. The work the cultivation of monocultures (included in the studied consortium) was also carried out. The performed work the original approach was developed, the approach is based on a comparison of the growth rate of the microorganisms biomass of the consortium with the calculated additive dynamics. This approach is convenient to use to identify a complex regularity of changes of the types of interaction of microorganisms in the consortium in the form of a continuous function determined during the entire cultivation period. From the point of view of the synergies of the species of microorganisms entering the studied consortium in the active phase of fermentation, the "Slava" variety turned to be more profitable than the "Parus".

Research work was carried out in the State University "Transnistrian Research Institute of agriculture" in film greenhouses (spring-summer and summer turnover) and in the open field on the trellis. The aim of the work is to study the source material and create promising lines of cucumber with high parthenocarpic ability, yield and resistance to downy mildew to obtain on their basis heterosis hybrids of cucumber of universal type for various crop rotations. To achieve this goal in 2013-2017 the following tasks were identified: to study the collection samples and to identify the most resistant to downy mildew; to evaluate the source material and select the stable forms; to study the combinational ability of the main features and properties of the parent forms of cucumber hybrids (parthenocarpy, yield, disease resistance); to study the variability and inheritance of the main useful features and properties; to test promising cucumber hybrids for economically valuable traits and properties. The standards were hybrids Enthusiasm (selection RF) and Claudia (Dutch selection). In order to create a source material of parthenocarpic hybrids of cucumber resistant to peronosporosis, 20 samples of breeding material from different countries of origin were studied in the closed and open ground. Four maternal and six paternal forms, as well as eighteen large-humped hybrid combinations were evaluated by the topcross method according to the complex of economically valuable traits and properties. And full diallele the scheme of the seven lines and forty-two tuberculate hybrid combinations. The regularities of variability and signs manifestation in the first generation of hybrids are studied. Given information about the inheritance of the trait of resistance to downy mildew is a promising parthenocarpic hybrid combinations of cucumber created in the Transnistrian agricultural research Institute. Highlighted is sixty-six hybrid combinations of cucumber. Three samples that showed high resistance to downy mildew, was submitted to the State varietal Inspectorate of the Republic of Moldova and Transnistria under the name Condor, Orlan and Shegol.
