Genetic variability and correlation coefficients were estimated from seventy four rice genotypes for morphological traits. Highest GCV and PCV were reported for total number of tillers per plant, number of secondary branches in panicle, leaf length and straw yield. High heritability was observed for all the traits estimated. High heritability accompanied by high genetic advance as percent of mean was observed for plant height, total number of tillers per plant, panicle length, number of secondary branches per panicle, leaf length, leaf width, kernel breadth, 100-grain weight, kernel length/breadth ratio, grain yield per plant and straw yield. Grain yield per plant was positively and significantly associated with days to 50 % flowering, number of productive tillers per plant, number of secondary branches per panicle and straw yield.
