Abstract
The aim of this research was to study the agronomic traits of common proso millet ( Panicum miliaceum L.) used in productivity-enhancing plant breeding programs. The study was conducted in 2024-2025 on experimental field plots at the Aktobe Agricultural Experimental Station. Observations were made by using biometric measurements of plants height and morphological characteristics of their productivity. The biological material consisted of 176 proso millet genotypes of various origins; experimental data were collected for all the genotypes. Based on the results of a comprehensive assessment, the following genotypes that demonstrated superior thousand-grain weight, plant height, panicle length, growing period, and overall productivity were identified: Kormovoe 89, Yarkoe 6, Yarkoe 3, Merei (line Р-1553), Shortandinskoe 7, Shortandinskoe 10, K-10343, K-10312, K-9605, K-917, K-1923, Donskoe, Saratovskoe 7, Candidum 1025. These valuable genotypes can be recommended as sources for enhancing the productive properties of proso millet.
