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 and methodology. Lychnis coronaria is a perennial herbaceous plant with high decorative properties, with prolonged flowering in the second or third year of vegetation. The pubescent leaves form beautiful rosettes. The plant is undemanding to the growing conditions. The research material was the varietal population of Lychnis coronaria. The study was carried out in the open ground of the Moscow region (2014- 2021) on experimental plots of the flower crops sector of the FSBSI FSVC.Results. The most aligned form according to decorative features was identified – LC 1-21 with high seed productivity of inflorescences, decorative and winter hardiness. A variety testing and preliminary reproduction of a promising cultivar of Lychnis coronaria was carried out. This variety was transferred to the FSBI "State Export Commission" in 2021 under the name “Malinovy Rassvet”. Such signs as "plant height", "bush diameter", "number of ornamental shoots", "flower diameter" had a low or average variation value, which characterizes this sample as the most aligned. Thus, the cv. “Malinovy Rassvet” of Lychnis coronaria is recommended for cultivation and use for decorative purposes. 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. It is grown as a short-lived perennial. The main advantages of the variety are the color fastness of flowers when burned out in the sun, resistance to diseases and pests, high seed productivity.

The article presents the results of experimental research on the search, study and use of qualitatively new traits of varieties and lines of sweet pepper that can complement the existing assortment of crops and ensure the import substitution of foreign varieties and hybrids in domestic vegetable seed production.The purpose of the work. The aim of the research was to create new competitive varieties of sweet pepper to expand the range of crops in the framework of the development of domestic seed production.Methods. Scientific breeding work on the research topic was carried out by the Department of Breeding and Seed Production of the VNIIOOB-branch of the Federal State Budget Scientific Institution "PAFSC RAS" in 2020-2022 as part of the implementation of the State task on the experimental field of the Institute (Kamyzyak, Astrakhan region) according to generally accepted methods. In the experiments, the zonal agrotechnology of crop cultivation, recommended for irrigated agriculture in the Lower Volga region, was used. The objects of research were 7 promising samples of sweet pepper. The zoned varieties of sweet pepper "Gift of Moldova" and "Gift of the Caspian" were used as a standard.Results. The article presents the results of a study of economically valuable qualities and traits of breeding lines and new varieties of sweet pepper "Zarnitsa" and "Prince Caspian" VNIIOOB breeding. The sweet pepper variety Zarnitsa was created and entered in 2023 in the State Register of Breeding Achievements Approved for Use in the Russian Federation. Mid-season (118-120 days), characterized by early and amicable setting and ripening of fruits of an even, cone-shaped shape with a light green color in the technical and red in the biological phase of ripening. The average fruit weight is 150-160 g, fruit wall thickness is 0.5-0.6 cm, fruit yield is 55-60 t/ha, marketability is up to 93%. The sweet pepper variety Prince Caspian was created and submitted for state variety testing in 2022. Mid-season (120-125 days), prism-shaped fruits with green color in technical and red color in biological maturity. The average fruit weight is 175-180 g, the average fruit wall thickness is 0.7 cm, the average yield is 52-53 t/ha, the fruit marketability is up to 95%. As a result of the research, a promising breeding line SL - 154/20 with large cube-shaped fruits weighing 184 g and a wall thickness of up to 0.8 cm has been identified. Recommended for fresh consumption, canning and home cooking.Conclusion. The introduction of new varieties of sweet pepper into production will contribute to import substitution and food independence of the state.
