ABSTRACT
The genetic analysis of biparental crosses derived from two F2 populations (STV 2667 x MGG 330 and RMG 406 x LGG 407) of mungbean revealed that, variance due to females was higher than variance due to males for days to 50 per cent flowering, days to maturity and plant height. Variance due to males was higher for pods per plant, pods per cluster, seeds per pod, 100-seed weight and grain yield. Both dominance and additive genetic variance were significant for all the characters but the predominance of additive variance was observed. The degree of dominance revealed partial dominance for all the characters except for days to 50 per cent flowering and days to maturity in BIP-I (STV 2667 x MGG 330) where as, over dominance was recorded for the later two characters. Biparental mating or diallel selective mating system could be the best breeding method for improvement of the crop.
