Assessment of genetic variability and trait association in mungbean (Vigna radiata L.) genotypes during summer season

Abstract

Twenty four genotypes of mungbean (Vigna radiata L.) were studied to assess the parameters of genotypic variability, correlation and path coefficients among the yield and its contributing traits. Analysis of variance revealed significant differences between the genotypes for seed yield and its attributing traits except for the number of seeds per pod. Traits like harvest index, days to maturity, 100-seed weight, biological yield per plot, days to flowering and seed yield per plot exhibited high heritability estimates. High heritability coupled with high genetic advance was observed for biological yield per plot, harvest index, 100-seed weight and seed yield per plot, indicating the preponderance of additive gene action. Biological yield per plot, the number of pods per plant, the number of seeds per pod and the number of branches per plant exhibited highly significant positive correlation with seed yield. Biological yield per plot and harvest index had high positive direct effects on seed yield per plot.
