Studies on genetic variability, character association for yield and yield components in green gram (Vigna radiata L. Wilczek)

Abstract

Twenty Mungbean (Vigna radiata L. Wilczek) genotypes were evaluated for the estimation of genetic variability parameters, correlation coefficient, Heritability and Genetic advance. The genotypes differed significantly for all characters. Higher GCV and PCV was observed for number of branches per plant (42.09%;62.27%) followed by number of clusters per plant (24.44%;30.08%), number of pods per plant (19.15%;25.36%), plant height (15.92%;17.59%), harvest index (11.14%;11.94%), seed yield per plant (9.72%;10.32%), seeds per pod (8.33%;12.44). High heritability observed for the biological yield per plant (97.96%) followed by harvest index (91.69%), seed yield per plant (88.73%), plant height (81.97 %) and 100 seed weight (70.09%) indicating the impact of additive gene expression. The plant height, number of primary branches per plant, number of clusters per plant, number of pods per cluster, number of pods per plant, number of seeds per pod and 100 seed weight had highly significant and positive correlations with seed yield at both genotypic and phenotypic levels.
