The analysis of genetic variability was done for forty-six rice genotypes in the student instructional farm during Kharif 2023-24 at Acharya Narendra Deva University of Agriculture& Technology, Kumarganj, Ayodhya. The experiment was conducted in a randomized block design (RBD) with 3 replications. In general, phenotypic coefficients of variation (PCV) estimates were higher than genotypic coefficients of variation (GCV) estimates for all the studied characters in all genotypes displaying the influence of environment effect on the studied characters. The higher estimates of PCV and GCV were observed for productive tillers per plant. High value of PCV was also recorded for 1000-grain weight. High value of broad sense heritability were recorded for days to 50 % flowering (95.34), number of fertile spikelets per panicle (93.81), days to maturity (93.11), number of spikelets per panicle (87.79), flag leaf area (83.09), plant height (83.02). High heritability coupled with high genetic advance was observed for number of fertile spikelets per panicle, number of spikelets per panicle, flag leaf area and days to 50% flowering, indicate the lesser influence of environment in expression of these traits and prevalence of additive gene action in their inheritance hence, amenable of simple selection.
