Abstract: The present investigation was conducted to evaluate the nature and magnitude of Genotype × Environment (G×E) interaction for yield and yield-attributing traits in rabi sorghum (Sorghum bicolor L. Moench). Eight sorghum genotypes-Phule Yashomati, Phule Anuradha, CSV-22, Parbhani Moti, Maldandi-35-1, Phule Uttara, Phule Madhur, and RSV-2371-were evaluated across multiple environments under rabi conditions. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Observations were recorded for grain yield and key yield components including plant height, days to 50% flowering, panicle length, test weight, and fodder yield. The analysis of variance revealed significant differences among genotypes and environments, indicating substantial variability. A significant G×E interaction was observed for most of the traits, suggesting that the performance of genotypes varied across environments. Stability analysis identified Phule Yashomati and Phule Anuradha as relatively stable and high-yielding genotypes across environments. The results emphasize the importance of multi-environment testing for selecting stable and adaptable sorghum genotypes suitable for rabi cultivation.
