Development of stable blackgram [Vigna mungo (L.) Hepper] genotypes by deciphering genotype × environment interaction using Eberhart-Russell and AMMI models
The genotype and environment (G × E) interaction is a key area of research for creating stable cultivars as it has a major impact on crop yield performance. In this study, we examined the stability and adaptability of the seed yields of elite blackgram genotypes in four Agricultural Research Centers of PJTSAU consisting of diverse environments in Telangana, India during Rabi 2019-20 using Eberhart-Russell and Additive Main effects and Multiplicative Interaction (AMMI) models. A combined analysis of variance showed significant differences between the varieties and the interactions between the varieties and locations for seed yield. Both Eberhart and Russell and AMMI1 model analyses of G×E interaction identified G1 (LBG-752) as the stable variety with respect to yielding ability suitable for cultivation under diverse conditions. Environments A, B, and C were found to be ideal environments for genotypes G7, G8, and G6, respectively, based on AMMI 2. The selected elite varieties based on different stability analyses could be used for further exploitation for cultivar release.
