The evaluated samples corresponded to the species: Rubus urticifolius, R. glaucus, R bogotensis, R. macrocarpus, R. niveus, R. robustus and a material that its taxonomic classification was not possible. The 20% of genotypes were located in the place of Buesaquillo, there was greater diversity of genus, followed by the places of Encano and Obonuco with a 12.31%, respectively. The Principal Component Analysis (PCA) and the Multiple Correspondence Analysis (MCA) allowed characterize samples and form groups by means of the method of hierarchical classification. Atotal of three factors helped explain the 79.96% of the variability expressed by qualitative variables, the first factor that explains 40.03% of the variability was the most important. The classification analysis conforms three groups, and characteristics with more contribution to the variability were the corolla color, stem pubescent, fruit form, shape leaflet and form of stipules. The PCA, the first three components explained the 71.16% of the total variation, was formed five groups; in the first group, the genotypes have important variables as the number of infructescenses per cluster and number of clusters per stem. The fourth an fiveth groups presented the greater weight and size infructescences of the population</p> ER -
