The present study was carried out to evaluate the extent of variability, heritability, genetic advance and genetic advance as a percentage of mean (GAM) in twelve mungbean (Vigna radiata (L.) Wilczek) genotypes for a range of morphological and biochemical traits. Field experiments were conducted during the Kharif seasons of 2013 and 2014 at the Agricultural Farm, Rajoula, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.), using a randomized block design with three replications, while biochemical estimations were performed in the Department of Crop Science, College of Agriculture, MGCGV, Chitrakoot. Observations were recorded on ten randomly selected plants from each genotype, and the data were analysed using IBM SPSS. Across both years, phenotypic coefficients of variation were marginally higher than genotypic coefficients of variation for all traits, suggesting that environmental influence on trait expression was present but relatively small. High estimates of both GCV and PCV for seed yield and number of pods per plant indicated substantial inherent variability and strong prospects for improving these traits through selection. Traits such as seed yield per plant, number of pods per plant, 100-seed weight, number of clusters per plant, pod length, polyphenol content, phytate content, total sugar percentage, fat percentage, methionine content, free amino acids, ash percentage and soluble protein percentage exhibited high heritability coupled with high genetic advance. This combination points towards the predominance of additive gene action and suggests that selection for these characters would be particularly effective in developing superior mungbean genotypes.
