Abstract: Two Hundred twenty five rice (Oryza sativa L.) genotypes including seven standard checks were evaluated during kharif 2015 for phenotypic characterization and assessment of variability parameters for yield and lodging resistance under irrigated transplanted condition. The result of ANOVA showed that there were considerable inherent genetic differences among check varieties for different characters. Among quantitative traits, the coefficient of variation was more than 10% for all the characters with the exception of days to 50 per cent flowering and panicle length. Highest coefficient of variation was recorded for grain yield per plant (34.19%) followed by harvest index (33.15%). Similarly, wide range of genetic variability was observed for almost all the lodging resistance traits. Highest coefficient of variation was recorded for lodging incidence percentage (65.94%). Based on the results of the adjusted means values, Hathi Panjari (H:144) identified superior for highest 1000-grain weight (47.01); IC 299800 for productive tillers per plant (12.53); whereas the accession Bashabhog was found superior for grain yield per plant (37.74) and harvest index (84.53). Minimum (0%) lodging incidence showed by IC 459207, IC 459643, IC125622 (Dashehra matiya), IC 125666 (Deshi safri) and Ganjeikalli.
