Fourteen diverse cultivars of paddy grown in a Randomized Block Design (RBD) at AKS University, Satna, during Kharif season on July 2022. Data were collected foreleven quantitative traits and estimated forvariance,genetic variability, heritability and genetic advance.The design of the experiment indicated highly significant differences for all the characters due to treatments. The analysis of variance indicated the existence of sufficient amount of variability among genotypes for all the studiedcharacters. The maximum GCV along with PCV was observed forgrain yield per plant (g) followed by panicle length (cm), number of spikelets per panicle, harvest index (%), kernel length (mm), number of panicles per plant. Higher estimates (h2b) >80% were observed for Number of spikelets per panicle, days to development, plant level (cm), number of panicles per plant, test weight (g), grain yield per plant (g), panicle length (cm). High heritability combined with high hereditary development for the person number of panicles per plant, number of spikelets per panicle, panicle length (cm), test weight (g) and grain yield per plant (g) indicating that these characters could be prominently governed by additive gene action.
