%X genetic diversity of natural rubber clones of the in sinchi institute¡¯s clone collection was assessed. clones of hevea brasiliensis (willd. ex adr. de juss.) muell.arg., hevea spp. (h. brasiliensis x h. benthamiana), and three more species of hevea genus are a part of the collection. seventy-two materials were characterized with twenty-eight morphological descriptors. they were later used to generate a similarity matrix through the analysis of multi-categorical variables, and to obtain clusters based on the matrix. a low variability between clones of h. brasiliensis and h. spp. was observed, presumably because of the direct descendants of most of the materials from crosses of parental pb 80, pb 5/51, pb 49 and tjir, exception made of clone gu 1410. clustering between some materials product of exclusive cross of pb series, a group between clones descendants of parental clones pb 86, and clustering between descendants of parental clones pb 5/51, were observed. clones from other species of hevea differ from this big group.
