Genetic association and path coefficient analysis in mung bean Vigna radiata (L.) Wilczek

Genetic variability and character association in 23 genotypes of mung bean for differentquantitative characters were studied in kharif (summer or monsoon crop) 2007. The analysis of variancerevealed highly significant difference for all characters, under study among the genotypes, indicating thepresence of sufficient amount of variability in the varieties. Thus there is ample scope for selection ofdifferent quantitative characters for crop improvement. The highest GCV and PCV were observed for harvestindex and pods per plant respectively. High estimates of genetic advance as percent of mean were observedfor 100 seed weight and harvest index. High significant correlation was recorded for pods per plant andharvest index at both genotypic and phenotypic levels with seed yield per plant and plant height, primarybranch per plant, clusters per branch and days to maturity had direct positive effect on seed yield.
