Abstract: Twenty four genotypes of rice were studied for genetic variability for seventeen economically important characters during kharif 2016 and kharif 2017 in Norman E. Borlaug crop research centren at Govind Ballabh Pant University of Agriculture and Technology, Pantnagar. The values of mean square were found significant for all the characters. Estimates of PCV were higher than the GCV and ECV values for all the characters, suggesting that these characters were relatively much influenced by the environment. The broad sense heritability estimates were high for grain breadth (99.89) followed by l/b ratio (99.65), grain length (99.11), gel consistency (97.95) and 1000 grain weight (95.64) whereas, gel consistency (28.51), plant height (18.97) and days to 50% flowering (16.11) revealed high genetic advance. The presence of high heritability and genetic advance in many of the traits indicates the presence of additive gene action, suggesting that these traits can be improved through direct selection. So, the overall result indicates the presence of enough variability in all the genotypes for development of improved rice varieties and the studied traits can be used for selection.
