Abstract: The present investigation was carried out at Agriculture Research Station, Palghar with seven rice varieties released by DBSKKV, Dapoli during four consecutive kharif seasons viz., 2015, 2016, 2017 and 2018 for five yield and yield contributing traits. The experiment was laid out in Randomized Block Design (RBD) with three replications. The analysis of variance of stability for variety, environment, Var. x Env., Env.+Var. x Env., Env. (Linear), Env. x Var. (Lin) and pooled deviation was highly significant for all the yield contributing traits under study. Based on observed results, all the varieties are stable for grain yield over the seasons. Among these, Karjat 7 and Karjat 184 reported high stability for days to 50 per cent flowering, panicle length, spikelets per panicle and grain yield, where the regression coefficient (bi) was near unity with low deviation from regression (S2di). Palghar 1 performed highly stable for panicle length, spikelets per panicle and grain yield, while the regression coefficient (bi) was near unity with low deviation from regression (S2di). Thus, Karjat 7, Karjat 184 and Palghar 1 are ideally adaptable, stable and may be recommended for cultivation for kharif season in north konkan region of Maharashtra state.
