Genetic variability, heritability and genetic advance studies for quantitative and quality traits in basmati rice (Oryza sativa L.)

Abstract

The present study was undertaken with an objective of estimation of genetic variability, heritability, genetic advance for yield components and quality parameters among thirty aromatic rice genotypes. The genotypes were evaluated in RBD and ANOVA results revealed the highly significant mean sum of squares among the genotypes for all the characters. PCV and GCV estimates were found high for almost all the traits of interest except for days to maturity, hulling percent and 100 kernel weight after cooking. High heritability was registered for all the traits except hulling percent, coupled with high genetic advance as percent of mean for all characters except days to maturity, 100 kernel weight after cooking and hulling percent, which indicates that these characters are largely controlled by additive gene action.
