The article presents the results of research conducted in the conditions of the south- east of the Central Chernozem region in 2022 and 2023. The characteristic of various millet varieties according to the complex of economically valuable signs, biological properties and morphophysiological parameters in the "flowering" phase is given. The coefficients of inter-varietal correlation between morphobiological, economically valuable, and physiological characteristics are calculated. In each year of the study, individual correlation moments were determined and analyzed for a specific variety. According to the results of the evaluation of the samples according to the productivity of the panicle, the weight of 1000 grains and the breeding indices, we identified the Stepnoye 9 variety. During the "flowering" phase, Stepnoye 9 was characterized by a significant shoot mass at a relatively low plant height, had a high intensity index, a large leaf area. This variety had high individual correlations between all the studied traits. The most significant signs for the formation of high productivity of the panicle are the growing season, the mass of 1000 grains, the leaf area and the aboveground biomass during the flowering period of millet. The formation of a larger grain is facilitated by a long growing season, high chlorophyll content, large leaves and large aboveground biomass during the flowering period of millet. The chlorophyll content was higher in the early ripening variety Saratovskoye 6 in all years, and in the medium-late Flavum 81-022 only in the favorable year 2023. The greatest leaf area and aboveground biomass were observed in medium-late varieties.
