Relevance. The creation of varieties with a complex of economically valuable traits, resistant to biotic and abiotic environmental factors, is the main direction in melon breeding. The market for vegetables and melons and gourds is very dynamic, the demands for varieties are constantly changing, therefore, it is necessary to introduce new varieties with high taste and commercial qualities, as well as capable of producing high yields in a changing climate. The aim of the work is to produce a new melon starting material for use in the breeding process.Materials and methods. At the Bikovskaya cucurbits breeding experimental station – branch of the Federal state budgetary scientific institution "Federal scientific vegetable center", research was carried out from 2018 to 2020. The object of research is samples from the collection of VIR, foreign and domestic selection, hybrid combinations obtained as a result of intervarietal hybridization. Collection samples of melon were studied in the nursery of the source material: 84 samples from the VIR collection, 26 samples of domestic and foreign selection were studied.Results. As a result of the research, samples of melon with economically valuable traits were identified that meet the requirements of selection. Paired crosses with zoned varieties of local selection were carried out with them. As a result of hybridization, hybrid combinations F1 were obtained, from which the best ones were selected for further breeding work. The obtained collection samples and hybrid combinations were evaluated in terms of taste, yield, resistance to environmental abiofactors, dry matter content, large-fruited, attractive color of the fruit and pulp As a result received a new source material for the selection of new varieties and hybrids of melons with valuable economic traits. The resulting hybrid combinations of F1 melon were tested against an infectious background. Hybrid combinations with the best performance will be further studied in a breeding nursery.

Over the years, breeders around the world have made significant changes to the architecture of plants of vegetable pea varieties. The changes made were aimed at increasing, first of all, the yield. New varieties should have an optimal combination of plant height, the number of productive nodes and increased resistance to lodging. Having achieved certain results, breeders find ways to improve the culture, further improving its economically valuable features. The article highlights the priority directions in the selection of vegetable peas in the Federal State Budgetary Scientific Institution «Federal Scientific Vegetable Center»(FSBSI FSVC), which are directly related to modern market requirements, and considers the specific factors encountered in breeding work, in the production sector and seed practice. Within the framework of import substitution and the achievement of food security of the country, the scientists of the center are intensively working to create new generation varieties: highly productive (by increasing the number of beans at the node and the number of seeds in the bean), suitable for mechanized harvesting (by obtaining appropriate morphotypes with increased stem strength or modified leaf shape) and with high quality indicators of green peas. There is also a constant selection for resistance to abiotic and biotic environmental factors that have been changing in recent years, both in the country and around the world. The article presents the main achievements obtained thanks to the experience and knowledge of the leading breeders of the center, specialists in seed production and production, as well as specialists in the field of plant immunity. Thus, selectively valuable forms with high productivity (up to 30 beans and more than 150 seeds per plant) were obtained, a variety with high resistance to lodging due to the strength of the stem was obtained. Work is underway to create varieties with high quality green peas and resistant to biotic and abiotic stresses.

In recent years, in the agricultural sector there is a tendency to increase the production of crop products. However, its quality is still not high enough. To improve the situation in the vegetable growing industry, an important place is given to improving breeding and seed production, since the variety and high-quality seeds are the main elements of modern crop cultivation zonal technologies. At the Federal State Budgetary Scientific Institution “Federal Scientific Vegetable Center” (FSBSI FSVC), vegetable crop breeding has been put on the innovative path of development, where modern methods are used along with classical ones: molecular markers on the main of economical important plant determinants, accelerated creation of homogeneous lines using the methods of doubled haploids and biotechnology of functional products for healthy nutrition. As a result of purposeful selection work, domestic varieties and hybrids of vegetable crops with fundamentally new qualities were created. The geographical location of the branches of the Center allows you to create breeding achievements for all potential regions of vegetable growing. In 2019, 36 varieties and hybrids of vegetables and melon crops were created, including cabbage, carrot, tomato, onion, onion Shallot, perennial onion, garlic, peas, bean, cowpea, pumpkin, cucumber, sugar corn, green vegetables culture, spicy-flavouring plant and floral crops. In order to provide the industry with pure-grade quality seed material and increase the productivity of crops due to the full use of the potential of the variety in the FSBSI FSVC, constant work is carried out in primary seed production. Zonal cultivation technologies have been developed that will allow growing domestic products in different soil and climatic conditions of the country. Wide introduction of achievements of the Russian vegetable growing science in agricultural production is capable to provide the population of the Russian Federation with high-quality, domestic production.

Relevance The main diseases that affect cabbage crops during the growing season are bacterioses, alternariosis, fusarium and others. Despite the success of breeding to create resistant varieties and hybrids in some years, there is a massive disease defeat of cabbage. Therefore, preventive measures aimed at reducing the level of cabbage diseases are of paramount importance. In recent years, in connection with the development of agricultural biotechnology for the prevention of cabbage diseases, biologics have been proposed based on the products of bacterial metabolism: antibiotics, enzymes, phytohormones, vitamins, etc. Methods In the Laboratory of Cole Crop Breeding and Seed Production of the Federal Scientific Vegetable Center in 2017-2018 conducted tests of biofungicides. The article presents the results of tests of biofungicides BisolbiSana and BisolbiFita to protect cabbage from diseases. Results The biological effectiveness of pre-sowing treatment of seeds and vegetative plants with biofungicides against cabbage altenariosis was 53.3-57.1%, against bacterial mucosa 40.2-47.8% depending on the variety (hybrid). Plant yield increased by 7-8.5%.

Relevance and research material. Flax is a perennial herbaceous plant with a high decorative value, with a long flowering, blooms in the first year of vegetation. The plant is undemanding to the growing conditions. As a result of multiple selection selections from a foreign variety, the long-term flax variety No. L-22 "Blues" recommended for use for decorative purposes was derived. The leaves and the bright color of the flowers provide a contrast to the perennial borders and flower beds. It looks good both in single and group plantings, as well as in cutting.Results. The study was carried out in the open ground of the Moscow Region (2015-2022) on experimental plots of the flower crops sector of the Federal Scientific Vegetable Center. The most aligned form according to decorative features is L–22 with high seed productivity of inflorescences, decorative and winter hardiness. Variety testing and preliminary propagation of a promising long-term flax variety was carried out. Signs such as "plant height"

Relevance. An important feature that determines the technological qualities of varieties and hybrids of beetroot is an erect, compact leaf rosette that persists until the end of the vegetation of plants. In this regard, much attention is paid to the selection of resistance to diseases affecting the leaves of plants, including Cercospora beticola Sacc. When creating resistant to Cercospora interline hybrids based on CMS, the selection of parent components plays an important role. In agroclimatic conditions of the Moscow region, Cercospora on industrial beetroot rarely reaches an economically significant threshold of harmfulness. However, in 2019, epiphytic development of Cercospora on summer first-year crops was observed in the block film greenhouse of the «Federal Scientific Vegetable Center», which allowed to assess the promising breeding material.Material and method. Phytomonitoring on beetroot plantings and sowing of the experimental production Department of the «Federal Scientific Vegetable Center» growing was carried out by methods of visual diagnostics and microscopy. Cercospora lesion in the breeding nursery was evaluated on an 11-point scale, the ranking of samples into five groups of resistance - according to the degree of disease development (R%). Analyzed: 28 sterile lines (А); 13 fertile lines of fixers (В); 25 lines of pollinators (С) and 38 hybrid F1 (АхВхС).Results. It was found that more than half of the studied lines were receptive to Cercospora. The share of relatively resistant lines was 13%. Most of them (8%) are ms - lines « obtained by pollination of CMS with mf-lines В. A close relationship (r=0.86-0.89) between the index of lesion of fixators and the degree of disease development of ms- lines was revealed, in some simple combinations a positive effect of heterosis on resistance to Cercospora relative to mf-В was noted. In the submitted sample F1 hybrids mainly observed between the nature of inheritance according to the degree of disease development (R, %), mixed effects the base line stability of pollinator mf-С (r=0,32) and a closer correlation of the stability of hybrid offspring the F1 with the resistant parent ms-line А (r=0.55). As a result of the evaluation, the most resistant to Cercospora ms- and mf-lines and derived from them hybrid F1, among which only 9% were included in the group of relatively resistant to C. beticola.

Relevance. The trend of increasing the area of protected soil and introducing new technologies in the cultivation of vegetable crops of food value can be traced every year. With the development of technology, the requirements for the quality and volume of seed material of hybrids have increased. The main constraints on seed production are the requirements for additional manual labor costs and the complexity of the process, in particular, pollination elements that need to be studied and improved.The aim studying some elements of technology, the optimal time between castration and pollination when crossing fertile tomato lines.Material and Methods. The research was conducted in 2022 year in greenhouse at the Federal State Budgetary Institution "Federal Scientific Vegetable Center". The objects of research were different methods of applying paternal pollen to the stigma of the maternal form. The experiment was carried out between maternal and paternal mid-fruited semi-determinate tomato lines in a hybrid combination. The variants of our experience include time-varying methods of pollen application. Pollination at the same time after castration is a control option, pollination after 4, 12, 24, 48 hours. Options with additional pollination the next day: pollination after 4 (+ after 24 hours), 12 (+ after 24 hours), 24 (+ after 24 hours), 48 hours (+ after 24 hours).Results. In the research, it was found that when pollinated with pollen of the paternal component 24 hours after castration of flowers with additional pollination the next day (24 hours later), the yield of seeds from one fruit on the average fertile maternal line of tomato exceeds 3 times compared with conventional pollination at the same time with castration.

The results of ecological variety testing of table carrot samples in soil and climatic conditions of the south of the Rostov region are presented. The experiments were laid in the period 2020 and 2021 in the fields of the Biryuchekut OSOS branch of the FSBI FNCO in the city of Novocherkassk, Rostov region. 12 samples of carrot plants from the first year of life were studied. The most productive samples were Marlinka – 59.7 t/ha Aksinya – 55.3 t/ha and Abaco F1 standard – 51.9 t/ha. The marketability of root crops was higher in the samples of Shantane 2461-82%, Aksinya – 78.9%, Boyar – 74.2% and Primorskaya 22-72.9%. The conducted research makes a great contribution to the process of selecting the source material for the creation of new varieties and hybrids of table carrots. The isolated samples can be recommended for commercial cultivation in the Rostov region and used in breeding work as a starting material.

For the Russian Far East (RDV), the subjects are calculated self-sufficiency of vegetable products and its connection with the population. A close correlation between these indicators has ignore once. In order to stabilize the population and consolidate it, it is necessary to increase dramatically the production of vegetables.
