Mung bean (Vigna radiata L. Wilczek) is one of the most important pulse crops due to the high content of protein as well as the ability to nitrogen fixation in soil. Seed yield is the most complex trait which highly influenced by other traits and also the environment. In this view, the study was aimed to evaluate the relationship between yield and yield attributing traits of sixty genotypes of Mung bean. The genotypes exhibited significant variability in respect to all the fourteen quantitative characters studied. Genetic variability studies showed presence of good amount of variation among the sixty genotypes. Highest PCV and GCV was recorded by seed yield followed by number of seeds per plant and primary branch length. The characters, seed yield per plant, number of seeds per plant, primary branch length, biological yield, harvest index, 100 seed weight, number of pods per plant, number of clusters per plant, plant height and number of primary branches had shown high heritability coupled with high genetic advance as percent mean. Seed yield per plant had shown highly significant and positive correlation with number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, number of seeds per plant, biological yield and harvest index at both phenotypic and genotypic levels. Path analysis showed that biological yield and harvest index were the most important characters for yield improvement.
