Stability performance was estimated for ten rice cultivars across five random environments in the valley. Analysis of variance revealed presence of significant genetic variability for all traits studied. G × E interaction was significant for head rice recovery. Mean squares due to environment plus cultivars × environments was significant for plant height, productive tillers m−2, grains panicle−1 and grain yield plot−1 Stability analysis for grain yield plot−1 revealed that the mean square deviation from regression was significant and the prediction of stability of grain yield across environments would be precise and reliable. Linear regression was also non-significant for all the cultivars except Poot Brear-II indicating that these cultivars were having average stability and were poorly adapted to these environments.
