Genetic Variability Analysis for Seed Yield and its Components in Mungbean (Vigna radiata L. Wilczek)

Abstract

Thirty-six genotypes of mungbean were studied for genetic variability of seed yield and its contributing characters in summer 2000 at Tirupati, Andhra Pradesh, India. High magnitude of variability was observed for pods per plant and grain yield per plant, while moderate variability was recorded for pods per cluster, clusters per plant, plant height and days to 50% flowering suggesting the possibility of their improvement by selection. High heritability coupled with high genetic advance was observed for pods per plant, grain yield per plant, pods per cluster, clusters per plant, plant height and days to 50% flowering, while high heritability and moderate genetic advance was recorded for seeds per pod, 100-seed weight and days to maturity suggesting that these traits were controlled by additive gene action.
