Information on germplasm diversity and its potential is fundamentally important in crop improvement even if part of it is not used directly in people custom food diet like multicolor beans (phaseolus vulgaris L.) that are not usual in Iranian food diet . In order to assess multicolor bean germplasm diversity that conserved in National lant Gene Bank ofIran , at first 245 accessions numbers were regenerated in experimental filed of ! eed and lant Improvement Institute , Karaj, then evaluated using augmented design in Khomein bean research station(Markazi province). Genetic material evaluated for agromorphological traits like plant and pod and seed characters according to descriptor of common bean .More traits showed variation , particularly for yield per plant, seed and pod per plant .High variation detected for qualitative traits by Shannon index such as flower color and pod position. Stepwise regression analysis demonstrate that most effective traits on seed yield per plant were seed number per plant and lOO-seed weight. Non- hierarchical (K- means) cluster analysis grouped beans in five clusters. The first five principle components accounted for !! of total variation. In the first and third components , reproductive phonological traits and regeneration phonological traits were important respectively, while second component described variation in seed yield per plant and its relation traits such as pod and seed per plant.
