Abstract

Variability, correlation and path analysis were worked out for nine characters related to grain quality and germination from the study of thirteen mungbean (Vigna radiata L. Wilczek) genotypes. Variability was high for seed yield/plant, seeds/pod, germination speed/day, swelling capacity and 100 seed weight which could be exploited in breeding for better germination percentage. Seed weight, density, volume, swelling capacity and germination speed/day were positively correlated with germination percentage but were negatively correlated with seeds/pod. Path analysis, however, showed that 100 seed weight and germination speed/day had high direct positive effect on germination percentage. The study suggested that 100 seed weight and germination speed/day must be given preference in selection along with optimum seed density, volume, swelling capacity to select superior genotypes of mungbean with high germination percentage.
