The classification of varieties of self-pollinated crops as to whether they will transmit high yield in crosses has hardly begun and needs more thorough study. The present study has revealed considerable heterosis, ranging from 108 to 252 per cent. for seed yield, in three intraspecific crosses of mungbean. It has also indicated the possibility of differences in combining ability of mungbean varieties. However, unlike tomato or egg-plant, the labour and cost of producing recurring F1 hybrid seed by hand pollination in mungbean will limit its wide-scale acceptance.
