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).","PeriodicalId":23570,"journal":{"name":"Vegetable crops of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141664171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grain of vegetable pea varieties is processed at canning factories, frozen, dried, and consumed fresh. Industrial cultivation of peas can be made more environmentally friendly by using biological preparations that contain growth-stimulating bacteria, for example Rhizobium species. With additional inoculation with rhizobacteria, legumes have higher values of traits characterizing vegetative development, biochemical parameters and yield; their immunity and resistance to abiotic stress increases as well.Methodology. The aim of our study was to evaluate the effect of additional inoculation of Rhizobium leguminosarum strain 245a on biometric and physiological parameters and yield of vegetable pea varieties. The experiment was carried out at Krymsk Experiment Breeding Station – a branch of VIR (Krasnodar Region, Krymsk). We studied six commercial cultivar: Prima, Mayak, Alpha 2, Vesta, Parus (leafless morphotype) and Patriot. The seeds were treated the day before sowing with an aqueous solution of the biopreparation Rhizotorfin (produced by ECOS BIOPREPARATIONS, St.Petersburg) and with water in the control variant.Results. The use of the preparation had a growth-stimulating effect on vegetable pea plants. An increase in the length of plants, the height of attachment of the lower pod and the number of completed pods on the plant was found. An increase in the content of dry matter in the total biomass of plants, stems with leaves and pods was noted when using Rhizotorfin. Also, inoculation with rhizobacteria contributed to an increase in yield. The effectiveness of the biopreparation depended on the conditions of the year. The maximum difference between the values of the studied traits for the control and treatment variants was in 2023 - with a uniform distribution of precipitation and optimal temperatures during the growing season. A genotype-dependent reaction of vegetable pea plants to seed treatment with bacteria Rhizobium leguminosarum strain 245a was revealed. The most responsive to additional inoculation is the variety Parus of the leafless morphotype. The values of most biometric and physiological traits and yield in this genotype were significantly higher in the variant with the use of the Rhizotorfin biopreparation. Based on the results obtained, we recommend using the Rhizotorfin biopreparation when growing the variety Parus for commercial production.","PeriodicalId":23570,"journal":{"name":"Vegetable crops of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the roots have been extensively studied, less attention has been given to the biologically active compounds found in the leaves of R. rosea. An introduced population of R. rosea grows on the territory of the botanical garden of medicinal plants of the All-Russian scientific research Institute of medicinal and aromatic plants (VILAR). The possibility of cultivating this species in the conditions of the Moscow region is being studied.Material and Methodology. The objective of this study was to investigate the composition of phenolic compounds in R. rosea leaves from VILAR biocollection using ultra-efficient liquid chromatography combined with mass spectrometry. Extraction was carried out with 80% acetone. An ultra-high performance liquid chromatographic system with a photodiode array detector and mass spectrometer was used for the analysis of phenolic compounds. Identification was carried out using UV- and mass spectrometry data.Results. As a result of UPLC-DD-MS analysis, peaks of 20 phenolic compounds were detected in R. rosea leaves, of which 19 compounds were tentatively identified. The leaf extract contained eight phenolic compounds from the group of galloyl-glucoses (three isomers of monogalloyl-glucose, trigalloyl-glucose, two isomers of tetragalloyl-glucose, two isomers of pentagalloyl-glucose), two gallotannins (isomers of hexagalloyl-glucose), five flavonoids (four herbacetin derivatives and one gossypetin), phenolic acids (caffeoyl-malic and ferulic acids), arbutin and esculetin.

The aim of this review was to present genuine evidence on the role of agroforestry in ecosystem conservation and mitigation of climate change impacts. Compared to monocropping and open cereal-based agriculture, agroforestry has made a more significant contribution to ecosystem conservation and in reducing carbon dioxide emissions. However, it has been found that agroforestry contributes less to carbon sequestration than natural forests. Carbon sequestration through above-ground and underground biomass, carbon emission reduction from deforestation, and microclimate adjustment are key measures for mitigating climate change. Agroforestry systems provide essential ecosystem services, such as food, fuel wood, fodder, income, and improved soil production, which enable communities to cope better with the impacts of climate change.

Cercospora leaf spot (Сercospora beticola) is a widespread disease of table beet that reduces the yield of root crops in many beet-growing regions. Annual losses from cercosporosis amount to 30-40%, and in the years of epiphytotic diseases – 50% or more. The fungus has a complex intraspecific structure, includes many pathotypes and races, which should be taken into account when breeding for resistance. The main method of creating resistant forms of table beet to C. beticola is the selection of cercospore-resistant lines in the natural manifestation of the disease and on artificial backgrounds. In open ground conditions, it is not always possible to assess the resistance of table beet to cercosporosis, since cercosporosis is weak in some hot and dry years. Therefore, laboratory assessment methods are important to accelerate the breeding process. The purpose of the research is to carry out an immunological analysis of beet lines in the field and laboratory conditions for the selection of sustainable material.Materials and methods. The assessment of beet variety samples for resistance to cercospora blight was carried out in open ground conditions on the basis of the All-Russian Scientific Research Institute of Vegetable Growing – branch of the FSBSI Federal Scientific Vegetable Center (Moscow region).
