The experiment was conducted to test the 30 mungbean genotypes along with one check (Samrat) to study their genetic variability, correlation and path analysis. The experiment was conducted at Field Experimentation Center, Department of Genetics and Plant Breeding, Sam Higginbottom Institute of Agriculture Technology and Science, Allahabad during kharif, 2015 in Randomize Block Design with 3 replications. Significant differences were found among 30 genotypes for 12 quantitative characters in analysis of variance. Maximum genotypic coefficient and phenotypic coefficient of variation was recorded for seed yield per plant, primary branches per plant and seed index. Maximum heritability was recorded for biological yield, while maximum genetic advance (as percent of mean) was recorded for seed yield. Among all the characters studied, pod length, Pods/plant, seeds per pod, showed positive significant correlation and positive significant direct effect on seed yield per plant, suggesting due priority should be given to, pod length, Pods/plant, seeds per pod, for yield improvement.
