The present study was conducted at Agricultural and Horticultural Research station, Ponnampet, Karnataka. Experiment was consist of 23 rice genotypes that were evaluated to study genetic variability, heritability and genetic advance for grain yield and four yield associated traits. The experiment was conducted using Randomized Complete Block Design with two replications during the 2016 kharif main cropping season. The analysis of variance revealed statistically significant differences (p<0.05) indicating the existence of genetic variability among the 23 genotypes for all the traits studied. Significant differences were observed for grain yield that ranged from 4093.00 to 7177.00 kg/ ha with overall mean value of 6323.00 kg/ha Higher PCV and GCV values were exhibited by yield kg/ha which suggests the possibility of improving this trait through selection. The highest heritability was recorded for days to fifty per cent flowering followed by yield kg/ha, panicles per meter square and plant height. High to medium heritability coupled with high GCV and high genetic advance as percentage of means were exhibited for plant height, panicles per square metre. High genetic advances as percent of means were recorded by yield kg per hectare, panicles per square metre, Plant height (cm) and days to fifty per cent flowering.
