Character Association and Genetic Variability in Mungbean (Vigna radiata L. Wilczek)

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