Ten diverse genotypes of green gram (Vigna radiata L. Wilczek) were evaluated for yield and nine other economic traits during the kharif season of 2006 at Crop Research Centre of Sardar Vallabh Bhai Patel University of Agriculture & Technology, Meerut. The study revealed considerable genetic variability among ten genotypes for days to 50% flowering, days to 75% maturity, plant height (em), number of productive branches per plant, number of productive pods per plant, number of seeds per pod, 100-seed weight (g), biological yield per plant (g), harvest Index (%) and seed yield per plant (g). High heritability coupled with high expected genetic advance observed for harvest index, pods per plant, seed yield per plant, biological yield per plant, 100-seed weight, seed per pod, plant he1ght and number of productive branches per plant revealed the preponderance of additive gene effects in the expression of these traits. Seed yield per plant exhibited positive association with harvest index followed by days to 50% flowering at genotypic and phenotypic levels. Based on these findings, it is suggested that selection may be an effective tool for the genetic improvement in mungbean.
