 ABSTRACT

In the present investigation, 26 F2s of mungbean were used for variability, heritability and genetic advance for 10 traits. Analysis of variance revealed highly significant difference among all the characters suggesting sufficient amount of variability. The high genotypic coefficients of variation were observed only for seed yield per plant. High estimates of heritability was observed for days to flowering, seed yield per plant, days to maturity, number pods per plant, and number of seeds per pod. Genetic advance expressed as percent of mean was observed high for seed yield per plant, number of branches per plant. There was high to moderate heritability coupled with high to moderate genetic advance for seed yield per plant, number of pods per plant and number of seeds per pod indicated the involvement of additive gene action and scope of improvement in these traits through selection.

Key words: Mungbean, GCV, PCV, Heritability, Genetic advance, Genetic advance as per cent of mean.
