Adaptability indicators of promising soybean varieties according to the traits ‘productivity’ and ‘oil yield’ per an area unit in the Ryazan region

Soybean (Glycine hispida) is an interesting and significant crop in plant production, as it is highly profitable and promising due to a number of valuable economic traits. The current study was conducted at the Institute of Seed Production and Agricultural Technologies (ISPA - branch of FSAC VIM), located in the Ryazan Region from 2020 to 2024. The purpose of the current work was to study the adaptability of soybean variety samples according to the traits ‘productivity’ and ‘oil yield’

per an area unit and to establish the potential for using these lines in breeding. The experimental plot was of dark gray, heavy loamy forest soil with 4.95% of organic matter, 213 mg of available phosphorus per a kg of soil, 155 mg of available potassium per a kg of soil, and 0.23% of total nitrogen, pHsalt = 4.91 units. The adaptive properties of promising soybean varieties were assessed in the nursery of the Competitive Variety Testing. To calculate adaptability parameters there have been used such indicators as an indicator range (d, %), a standard deviation (σ), a coefficient of variation (Cv, %), a phenotypic stability factor (SF), an adaptability coefficient (AC), homeostasis (Hom), and stress resistance (Ymin-Ymax) using the appropriate methods. There has been revealed that the meteorological conditions of the year such as the temperature of the vegetation period (r=+0.893+0.04) and the precipitations during the seed filling stage (r=+0.919+0.03) had a significant impact on the formation of the trait ‘productivity’. A comprehensive rating based on a combination of adaptability traits has identified the best variety samples (L 4146 x Brawalla) x Kasatka and the variety Kasatka, characterized by resistance to changing weather conditions and capable to form large productivity and oil yield per an area unit in the conditions of the Ryazan region.
