Abstract:
The research was conducted at S.D.A.U. during kharif-2019 to study variability, heritability, genetic advance, correlation and path coefficient in a set of thirty genotypes of mungbean [Vigna radiata (L.) Wilczek]. Randomized block design was used with four replications. Ten traits showed significance differences in analysis of variance. Majority traits showed higher genotypic variance than their relevant environmental variance. PCV values were closer to GCV for most of the characters. Seed yield per plant and number of branches per plant had highest GCV. Number of branches per plant, seed yield per plant and100-seed weight expressed high genetic advance and high heritability. Seed yield per plant gave highly significant and positive correlations with number of pods per plant, pod length, 100-seed weight, while highly significant and negative with days to flowering. Highest positive direct effect on seed yield was noticed by 100-seed weight followed by number of pods per plant and days to flowering. Negative direct effect on seed yield was found with plant height followed by protein content. In conclusion, 100-seed weight, number of pods per plant, number of seeds per pod, pod length and number of branches per plant were found key contributors for seed yield.
