ZAMORANO M, Adriana et al. Morphologic characterization of blackberry on the departments of Valle, Cauca y Nariño of Colombia. Acta Agron. [online]. 2007, vol.56, n.2, pp.51-60. ISSN 0120-2812.

36 materials of blackberry belonging to three species: R. glaucus , R. urticifolius and R. robustus were collected. The qualitative characterization separated the three species and it generated describers that allowed to identify form, type, margin, apex, color of leaf in the leaves, and presence of antocianinas and serosity in steams. The quantitative characterization identified characteristics of commercial importance (high fruit weight, few thorns in the stem and high Brix degrees) in the materials 3 and 31 of the Collection. The multivaried analysis of quantitative characters for stem and fruit conformed 5 groups that varied in distance of internodes, length of pedicels in the male branch, length of petioles in female and male branch, wide of leaf, fruit weight, length of the heart of the fruit and number of drupes.

Palabras clave : Rubus glaucus; R. urticifolius; R. robustus; quantitative characters; qualitative characters.
