Genetic variability and correlation patterns were studied in 100 mungbean accessions to bring out the genetic association of different attributes toward yield. Large number of Taiwan accessions had green hypocotyl, while most of the Indian and Pakistani accessions were with purple hypocotyl. Small number of genotypes were found without pubescence. Shiny green, dull green, yellowish green, pale red and black spotted seedcoat colours were recorded. Highly significant differences were observed among the genotypes for all the quantitative characters indicating considerable range of variation. High genetic coefficient of variability coupled with high heritability and genetic advance was observed for average peduncle and internodal, pods per plant, 1000 seed weight and grain yield per plant indicating the predominance additive gene effects. Grain yield per plant was positively and significantly associated with 1000 seed weight, pod length, pods per plant and nodes on main stem, whereas average peduncle length showed significantly negative association with grain yield.
