Relevance. Pea rust regularly damages the vegetable pea crop in the Omsk region. The harmfulness of the disease has begun to intensify in recent years; in years favorable for the development of the disease, the damage to susceptible varieties can be 100%. Therefore, breeders are forced to constantly search for new sources of resistance genes due to the rapidly developing rust pathogens. The goal of our research is to screen samples of a vegetable pea collection under field conditions in the southern forest-steppe of Western Siberia and identify sources of resistance.Material and Methodology. As an object for study, 72 samples of vegetable peas were taken from the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center (FSBSI FSVC) and the “Federal Research Center of the All-Russian Institute of Plant Genetic Resources named after. N.I. Vavilov" (VIR). The research was conducted over four years from 2020 to 2023. in the conditions of the southern forest-steppe of the Omsk region. The records were carried out in accordance with the “Methodological instructions for studying the collection of grain legumes”.Results and Discussion. As a result of the studies, it was established that the resistance of vegetable peas to rust depends on both the genotype and weather conditions. Weather conditions had the greatest influence on the development of the disease (the factor’s share was 51.5%), the contribution of the genotype was also significant and amounted to 44.8%. The resistance of collection samples to rust in the conditions of the Omsk region varied from low (2.8 points) in warm and humid weather to very high (7.8 points) in dry and hot weather. The main influence on the spread of rust is exerted by the hydrothermal conditions of the “flowering – ripening” period (r=-0.98±0.11). Plant resistance to rust varies greatly depending on growing conditions (Cve=20.2-54.6%). The variety Darunok had the least variability of the trait over the years (Cve=20.2%), which will most consistently maintain resistance when the infectious load increases. As a result of screening of collection material of vegetable peas, sources of partial resistance to rust were identified for breeding in Western Siberia: varieties Darunok, Namorodok (Federal Scientific Vegetable Center (FSBSI FSVC)), Orel, Cruiser, Vityaz, Flagman-8, Nemchinovsky 46, B-579, In Memory of Khangildin (VIR collection).

Relevance. The state of Russia's agro-industrial complex determines the country's national security, as it provides the population with quality agricultural products and raw materials, which affects state sovereignty. According to a number of analysts, in commercial vegetable growing, about 80 % of sown areas are annually sown with imported varieties and hybrids, and this is a vulnerability in ensuring the industry's independence and the country's competitiveness. Strengthening technological sovereignty in the field of vegetable production is one of the priorities of the state agrarian policy, as well as the main focus of scientific organisations and private companies.Results. Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center (FSBSI FSVC) is a major scientific center of the industry, which can compete with foreign companies with its breeding achievements. The article shows the leading position in the breeding of vegetable and melon crops FSBSI FSVC, which actively conducts research on private genetics, biotechnology, contributing to the acceleration of the breeding process; varieties and hybrids are created that combine consistently high productivity, early maturity, resistance to biotic and abiotic stressors, high quality products with an optimal content of biologically active substances to obtain potential raw materials and products of functional action; development of resource-saving, environmentally safe, high-precision technologies for cultivation of vegetable and melon crops, taking into account species and varietal characteristics, as well as scientific bases and practical recommendations for production of original seeds taking into account zonal specifics.However, there are problems hindering the introduction of breeding achievements: the increased cost of registration of breeding achievements in the State Register of Selection Achievements of the Russian Federation of the Russian Federation, bureaucratic difficulties in their approbation, which arose for breeders after the adoption of the new law "On Seed Production". In order to solve the problems of seed production, the Ministries in charge of vegetable production have launched a sub-programme "Development of breeding and seed production of vegetable crops", which aims to increase the production of domestic competitive seeds and brings together the state, science and business.

Microgreens are valued for their freshness and refined taste, and by adherents of a healthy diet – for their saturation with vitamins, trace elements, antioxidants, enzymes and valuable protein. The product enjoys steadily growing demand not only in the production segment (restaurants, cafes, supermarkets), but also in home cultivation – «vegetable garden on the window». Among vegetable crops, vegetable pea micro-greens are very popular, especially varieties with a mustachioed leaf type. It is this product that helps culinary masters to give products bright visual and taste accents. Few people know that among legumes, in addition to vegetable peas, there is an excellent alternative with no less nutritional value. This is a micro-green of vegetable beans. Bean shoots are more fleshy and juicy, crispy, sweet with a nutty taste, and most importantly, absolutely everyone can grow them. Obtaining microgreens from vegetable bean culture is a promising direction, since its nutritional value and biochemical composition are comparable to the microgreens of vegetable peas. The content of the main nutrients on average for the studied varieties of breeding of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center (FSBSI FSVC) is: protein – 20-35% (dry weight), ascorbic acid – 0,51 mg/g, carotenoids – 0,48 mg/g, monosaccharide – 1,15%, dry matter – 10,62%. However, vegetable beans have an undeniable advantage in cultivation – it is the possibility of using up to two or three cuts from one crop, due to the ability to form additional shoots when using the method of cutting under the «root». The yield from the container when sowing 100 seeds obtained in two cuts ranged from 320 g to 400 g, depending on the variety and method of cutting. The highest yield was obtained from the cv. Velena, which forms about 200 g of fresh shoots both in the first and second cut. According to the results of our research, it is recommended to use two cuts for the cv. Belorusskie and cv. Russkie chernye, while the cv. Velena is able to give a full-fledged microgreen even with the third cut.

Relevance. Maintaining the phytosanitary condition of vegetable and melon crops is an important component in the technologies of cultivation of new and promising varieties and hybrids, since losses from diseases of various etiologies reach 30% or more. This determines the need for immunological studies of the resistance of vegetable and melon crops to phytopathogens of various etiologies, where the basis of the strategy for creating new varieties and hybrids is the joint work of a breeder and a phytopathologist. To do this, it is important to conduct an annual study of the species composition in order to identify new harmful objects that have a negative impact on the profitability of production, as well as to develop measures to protect vegetable crops from the most harmful and economically significant pests and diseases.Methodology and Results. The extensive experimental network of the Federal Scientific Vegetable Center (FSBSI FSVC) in various ecological and geographical zones allows testing varieties and hybrids of vegetable and melon crops in various soil and climatic conditions, including evaluating them for the most harmful phytopathogens in these regions. This review article briefly highlights the main stages of the history of development and current trends in phytopathological research in Russia and our center. The most significant achievements of scientists of the FSBSI FSVC are presented, aimed at a comprehensive study of the current state of populations of pathogens on vegetable and melon crops, resistance factors controlling the interaction of organisms in pathosystems, including genetic ones, optimization and development of new methodological approaches in breeding for immunity and scientific justification of recommended modern protection systems.

Relevance. Large differences in the climatic conditions by the region Altai by years determine the prevalence and harmfulness of diseases, therefore, monitoring by the dynamics of disease development and assessing their harmfulness are relevant and necessary measures. An important role in modern plant protection technologies against diseases play biofungicides. The main advantages of biofungicides as compared with chemical plant protection products are safety for humans and the environment, short waiting times and the possibility of use throughout the growing season, the absence by risks of the emergence of resistant pathogens, the creation of conditions for the natural self–regulation of agrocenoses.Materials and Methods.
