Abstract: The present investigation consists of 29 rice genotypes including one check, which were obtained from IRRI (Philippines) and others from Department of Genetics and Plant Breeding, SHUATS, Allahabad. The experiment was conducted during Kharif 2016 in RBD with three replications. The data were recorded for 13 quantitative characters to study genetic variability, heritability and Genetic advance. Analysis of variance revealed that there is considerable variability among the genotypes. Genotypes NDR-1045 (2%EMS), IRRI-181, AOQINH-2HAN, CT-16658-S-2-8-35-R-3-1-3MP and NDR-359(C). A close perusal of variability coefficients revealed that the differences between PCV and GCV was small indicating little influence of environment on the expression of the characters studied. High to moderate estimates of GCV and PCV were recorded for grain yield per hill, harvest index, spikelets per panicle, tillers per hill, flag leaf length, panicles per hill. High estimates of heritability were observed for spikelets per panicle, days to maturity, biological yield, grain yield per hill, panicles per hill and tillers per hill. High estimates of heritability along with moderate to low estimates of genetic advance were observed for spikelets per panicle, seed yield per plant, tillers per plant, panicles per plant and biological yield per hill.
