Study of genetic variability and association on yield and yield components in Mungbean (Vignaradiata L.)

Abstract

Thirty five genotypes of Mungbean were evaluated in RBD for estimation of genetic variability, heritability, genetic advance, correlation coefficient for yield and its component traits. The estimates of heritability in broad sense were found higher in seeds per pod, Seed yield per plot and branches per plant. The genotypes showed wide and highly significant variation for all the traits. The estimates of GCV and PCV for pods per plant, number of cluster per plant, plant height and seed yield per plot showed very little differences indicating the greater role of genetic factors in the expression of these traits and ample scope for improvement. High heritability along with high genetic advance as percent of mean was observed for seed yield per plot, days to maturity, plant stand and plant height preponderance of additive gene action. The characters, Seed yield per plant showed highly significant and positive correlation with cluster per plant and plant height.
