The article presents the results of a study of the formation of morphometric features (plant height, basket diameter, weight of 1000 seeds, etc.) in sunflower in the steppe zone. The research was conducted in 2020-2021. They realized their biological potential to the maximum and formed high indicators of these elements of the Altai, Gin M, Martin varieties and the LG 5377 hybrid.
