ABSTRACT
Genetic variability, genotypic and phenotypic coefficients of variation, heritability and genetic advance for nine characters in seventy genotypes of rice were studied. The analysis of variance revealed that there were highly significant differences for all the characters among the genotypes. The estimates of genotypic and phenotypic coefficients of variation (GCV and PCV) were high for all the characters except days to 50% flowering and Days to maturity. Heritability and genetic advance were high for all the characters except days to 50% flowering and Days to maturity, which had moderate genetic advance along with high heritability indicating the involvement of additive and non-additive type of gene action respectively in controlling these characters.
Key words: Rice, Genetic variability, Heritability, Genetic advance.
