Abstract
The present investigation was undertaken to evaluate ten germplasm of mung bean, used to estimate genetic variability, heritability and genetic advance for 16 characters. The results showed significant differences among the mung bean genotypes in all characters. All the characters had a larger PCV, showing the enfluence of the environmental variable on their expression. In the present study, PCV is higher than GCV for all the characters under study. High heritability coupled with high genetic advance indicates additive gene action. Heritability for broad sense was estimated for all the studied characters observed range from 33.6 to 98.175%. Genetic advance as percentage of mean is observed range from 2.484% to 26.315%. All these characters coupled with hhigh heritability coupled with high genetic advance can be used for the selection of lines as a parents for further breeding programme, where as in breeding programme these traits were more important for selection.
