Abstract

The article presents data on the most important indicators in the cultivation of oilseed flax, obtained during research at the Agricultural Experimental Station Zarechnoye LLP for 2022. The most intensive plant growth was observed after the flax plants passed the herringbone phase up to the flowering phase, the linear development of plants stopped. Intensive root growth in depth occurred in the early phases of development. During our research, flax plants have placed increased demands on heat, especially during the ripening period. At low air temperatures, the germination of seeds and the emergence of seedlings were significantly slowed down. According to the results of the research, promising varieties were identified that exceed the indicators of the standard variety. 36 varieties were sown in the nursery of oilseed flax in 2022. All of them are part of the world collection, they belong to Russian, Canadian, Ukrainian, etc. breeding. The domestic selection is represented by 6 varieties: Kustanayskaya-5, Kazar, Kostanay 11, Ilyich, Slavyachil, Altyn. The zoned Kazar variety was taken as the standard, which was located every 5 varieties. In regions where oilseed flax is cultivated, fusarium wilt is the main predominant type of disease. Resistance to fusarium wilt was determined by counting plants after germination and before harvesting in the infected area. Such varieties as Isilkulsky, Kinelsky 2000, Ilyich, Slavyachil, Kazar, Osean, Triumph, Istok, Antares, Kustanaysky 5 turned out to be moderately stable.
