PATH ANALYSIS, ASSOCIATION AND VARIATION OF GRAIN YIELD ATTRIBUTES IN MUNGBEAN (Vigna radiata L.Wilczek)

Fourty five advance lines including four varieties of mungbean were studied for genetic variability, heritability, genetic advance and character association for seed yield per plant and its component traits. The maximum variability was observed for pods per plant followed by seed yield per plant, clusters per plant, 100-seed weight and branches per plant. Heritability estimates were observed to be high for all the traits except branches per plant and seeds per pod. High expected genetic advance coupled with high heritability estimates were for seed yield per plant, days to flowering and plant height indicating least influenced by the environmental variation. Seed yield per plant had significant and positive direct effect & association with clusters per plant, pods per plant, 100-seed weight and grains per pod.
