Abstract: A field experiment was conducted to evaluate the genetic variability and character association on 27 genotypes of greengram (Vigna radiata L.) at Instructional Farm Jaguli, Bidhan Chandra Krishi Viswavidyalaya during 2012 and 2013.The experiment was laid out in Randomized Block Design with two replications. Analysis of variance revealed significant differences among genotypes for all the eleven characters which provides enough scope for significant improvement of the traits through selection. Marginal difference between GCV and PCV was observed predicting least environmental influence. High heritability accompanied by high genetic advance was observed for seed yield plant -1 followed by 100 seed weight, number of branches plant - 1 and number of pods plant -1 indicating importance of additive gene effects which may facilitate the adoption of simple breeding strategies to obtain desirable changes with respect to these characters. Seed yield plant-1 had shown significant positive correlation with number of pods plant-1,100 seed weight and positive correlation with pod width, protein content which also exerted positive direct effect on yield...
