Genetic Variability, Heritability and Genetic Advance in Karan Rai (Brassica carinata A. Braun)

The present investigation was undertaken to evaluate the performance of eight genotypes of Karan rai (Brassica carinata) and to estimate the variability, heritability and genetic advance of agronomic traits of these genotypes. A high degree of significant variation was observed for all the characters studies. Maximum genotypic and phenotypic coefficients of variation (GCV and PCV) were found in seed yield/plant followed by days to 50% flowering, number of siliqua/plant and 1000 seedweight. High heritability estimates with genetic advance as percent of mean were observed for days to 50% flowering followed by seed yield/plant, number of siliqua/plant and plant height. The study showed that there are variation in the extent of genetic variability, heritability and genetic advance in traits under study which can facilitate selection for further improvement of important traits of karan rai.
