Abstract:
Forty eight rice (Oryza sativa L.) genotypes including four checks has been planted in Randomized Block Design, within two replications, were evaluated during kharif 2018 for twenty five quantitative traits to examine the nature and magnitude of variability, heritability (broad sense) and genetic advance. Analysis of variance revealed that the differences among forty eight genotypes were significant for all the characters except length of leaf blade and width of leaf blade. Among the all traits gel consistency exhibited high estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) followed by unfilled grain per panicle, gel consistency, grain yield per panicle and number of effective tiller. Broad sense heritability was highest for Gel consistency, which suggested that this trait would respond to selection owing their high genetic variability and transmissibility. Maximum genetic advance as per cent of mean was recorded for Gel consistency with high value of heritability.
