Quantitative Analysis Of Rice Genotypes (Oryza Sativa L.)

Genetic variability, genotypic and phenotypic coefficients of variation, heritability and genetic advance for eleven characters in one hundred and fifty genotypes including five check varieties of rice were studied. The analysis of variance revealed that there were highly significant differences for all the characters Leaf Length , Panicle Length , 100-seed Wt , Germination %  and Coleoptiles Length. The estimates of genotypic and phenotypic coefficients of variation (GCV and PCV) were high for all the characters except days to 50% flowering and panicle length. Heritability and genetic advance were high for all the traits except Yield/ Plant and Fertile Grains/ Panicle and Radical length which had a moderate magnitude of genetic advance, which had moderate genetic advance along with high heritability indicating the involvement of additive type of gene action in controlling these characters.
