Abstract: Three hundred and ten mungbean lines were evaluated in the field for 9 quantitative traits at NARC, Islamabad, Pakistan (33.40 ^o N and 73.07^o E). These showed high variance for yield contributing characters except pod length, seeds/pod and seed weight. Germplasm under investigation displayed a wide range of diversity for most of the traits. Pure-lines with unique characters which could help to identify, select and hybridize land races to induce evolution for important traits were identified and for that matter 44 pure-lines were selected and recommended for testing under wide range of agro-ecological condition in pursuit of best mungbean cultivars. Data on harvest index revealed that the genotypes from 25 to 40% harvest index exhibited better performance and thus this range is suggested as one of the criteria for future improvement in mungbean.
