The present experiment comprised of fifty-five mungbean germplasm lines tested over two years to assess inter-relationship of agronomic traits including seed yield under deficit moisture stress. In stress condition heritability in broad sense (h² in %) was the highest for seed yield per plant followed by no. of pods per plant. Seed yield/plant, no. of pods/plant showed the high genetic advance coupled with high heritability in deficit moisture stress. Resembling the action of additive gene in controlling these characters and selection would be rewarding for enhancement of yield. It was found that single plant yield/plant showed highly significant positive correlation with number of pods/plants, number of clusters per plant, no. of pods per cluster, no. of seeds per pod and plant height. However, path analysis revealed that pods/plant, hundred seed weight, no. of seeds per pod had the highest direct positive effect on single plant yield. Hence, for genetic improvement in the seed yield, direct selection of genotypes based on component traits exhibiting positive correlation and higher positive direct effect will be more effective and fruitful in mungbean under deficit moisture stress.
