Six lines of mungbean were crossed in a diallel manner to obtain 15 direct and 15 reciprocal F-crosses. They were planted in dry and late rainy seasons to observe for seed yield. 1,000-seed weight, number of seeds/pod and number of pods/plant. The analyses of variance revealed that all 6 parental lines expressed diversity in both dry and rainy seasons in terms of seed yield/unit area and 1,000-seed weight. Number of seeds/pod showed statistical different only in the dry season while number of pods/plant was significant in the rainy season.
