Study Gene-environment Interactions and Ecological Stability for Common Bean (Phaseolus vulgaris L.)

Crop productivity is determined by genotype, environmental effects and their interactions. Comprehensive evaluation of crop varieties based on their adaptability, plasticity and stability makes it possible to select the most promising varieties, high-yielding and adapted to many environmental conditions to improve productivity.

Five common bean varieties were tested in a randomized complete block design with three replications during two growing periods in (2022 and 2023) in the experimental field of Novosibirsk State Agrarian University, Russia.

Varieties, seasons and gene-environment interactions had a significant impact on the average yield of experimental varieties. Solnyshko, Viola and Kormilitsa varieties had a high average net yield in all environments, ranging from (2.29 - 2.71 kg/m²). Analysis of the interaction between genotype and environment (G × E) by the mathematical model of Elberhart and Russell and the GGE biplot chart shows that: Solnyshko and Kormilitsa varieties have stable yields and high adaptability to the environment.
