Abstract
Five parent lines of mung bean (Vigna radiata (L.) Wilczek) and all possible non-reciprocal single crosses among them were compared in respect of yield, leaf size, days to flower, days to first ripe pod, plant height, branch length, pods per plant and seeds per pod. Significant heterosis was found for all characters except days to flower, days to first ripe pod, and 1000-seed weight. In the highest yielding single cross, heterosis for yield was 154 per cent of the mid-parent and 137 per cent of the high parent, the high parent in this cross being the highest yielding parent line in the study. General combining ability (GCA) mean square were significant for all characters except pods per plant. Specific combining ability (SCA) mean squares were significant for plant height and branch length.
