The present investigation was undertaken to assess the stability for grain yield and yield attributing traits in eight genotypes of rabi sorghum (Sorghum bicolor L. Moench) across different environments. The genotypes evaluated were Phule Yashomati, Phule Anuradha, CSV-22, Parbhani Moti, Maldandi-35-1, Phule Uttara, Phule Madhur, and RSV-2371. The experiment was conducted in a Randomized Block Design (RBD) with three replications across multiple locations during the rabi season. Data were recorded on yield and its component traits such as days to 50% flowering, plant height, panicle length, test weight, and fodder yield. Significant differences were observed among genotypes, environments, and their interactions, indicating the presence of substantial genetic diversity and environmental influence. Stability analysis, carried out using the Eberhart and Russell (1966) model, revealed that genotypes Phule Yashomati, Phule Anuradha, and Phule Uttara exhibited high mean performance, regression coefficients near unity, and low deviations from regression—indicating wide adaptability and stable performance across environments. The study suggests that these genotypes are most suitable for consistent performance under variable rabi conditions.
