“…Favorable weather conditions, due to the optimal distribution of heat and moisture, contribute to productivity due to the full formation of beans and seeds, the duration of the growing season and the interphase period [3][4][5]. The yield of morphotypes and varieties increases with the formation of the correct plant morphology and from mustachioed varieties to leafy and chameleon varieties, the chameleon morphotype is adapted to conditions of high fertility and is resistant to drought [6][7][8][9].…”

The selection material and finished varieties of peas for sowing different morphotypes of the grain direction were assessed for the formation of a phytosanitary state and productivity, and the effectiveness of protection methods. During the growing season, leaf and stem diseases were observed with varying degrees of development and timing of manifestation (p. Ascochyta, p. Uromyces, p. Erysiphe communis G) with development depending on the year and genus of the pathogen from 0.2-40%. The development of the river. Ascochyta - 10-20%, r. Erysiphe - 11-49%, p. Uromyces - 0.2-20%. Some resistance was determined in 22% of varieties p. Erysiphe communis G., 11% p. Ascochyta and 14% p. Uromyces. The yield for the period of study of pea varieties of the sowing grain direction varied from 3.2 to 4.6 t/ha, stable yields in the morphogroup chameleon with an increase of 0.64 t/ha or 17% to the standard. Protection of peas requires mandatory pre-sowing treatment with a chemical disinfectant, a biological preparation with the inclusion of an agrochemical in the mixture, which contributes to the development of the root system, activation of growth vigor, and a 70-90% reduction in pathogenic fungi on seeds and roots. Fungicidal protection in the budding phase - the formation of beans contributed to the preservation of the crop by 0.3-0.4 t/ha.

The research was conducted at the Research Institute of Agriculture of the North-West, a branch of the Tyumen Scientific Center of the Siberian Branch of the Russian Academy of Sciences, in the Northern Forest-Steppe Zone of the Tyumen Region. The varieties of grain of the “chameleon” morphotype were evaluated according to productivity parameters. The study of breeding lines and varieties was carried out according to the type of competitive variety testing. Weather conditions during the research period varied significantly. The yield varied in the range of 2.4-5.5 t/ha, and on average over a number of years the yield was 4.06-4.16 t/ha. The yield exceeding the standard of the Sibirsky 1 variety was observed for 1 line out of 4 (TM06-457) by 2%. The seed productivity from an area of 1 m2 averaged 374‒431 g, with the standard being exceeded by the TM06‒257 and TM06‒457 lines. The varieties increased the vegetation period by 1.2‒1.8 days, lodging resistance increased by 0.4 points, the protein content was 19‒25%, with the standard being exceeded by 5.3‒5.9% for the studied lines, and the structural parameters of the plant were exceeded over the standard. Of the entire set of tested lines, the TM06-257 lines and the slightly inferior TM06-457 stood out for most of the plant structure parameters.

The studies were carried out in the conditions of the Krasnoyarsk forest-steppe on the basis of the Krasnoyarsk Research Institute of Agriculture. The weather conditions of the years of the study differed from each other: 2018 - very dry Hydrothermic Coefficient (HC) 0.60; 2019 - arid HC 0.89; 2020 - moderately humidified HC 1.32. The soil of the plot is ordinary heavy loamy chernozem with an acidity of the soil solution of 6.8 and humus content of 7.8 (according to Tyurin). The researches were carried out in accordance with the guidelines for the study of the collection of the world’s genetic resources of cereal legumes. For the study, 9 samples of peas of different morphotypes were taken. The proportions of the influence of genotype and year conditions on the characteristics of the productivity of the samples were determined - the number of unproductive and productive joints, the number of beans and seeds per plant, and the length of plants. The climatic conditions of the year of cultivation had the greatest influence on the main characteristics of productivity, such as the number of beans per plant, the number of seeds per plant, and the number of productive joints. In terms of the number of beans and seeds per plant, 75% was attributed to the influence of the conditions of the year and 45% to the influence of the variety and the interaction of factors, variety x year. The length of the plants was significantly influenced by the year of cultivation - 66%, the influence of the genotype was estimated at 24%, the interaction of factors at 10%. The factor of the year had a minimal effect on the number of unproductive joints - 19%, the influence of the variety was 80%.
