Objective. Determine the cultivated and wild species of Rubus in 53 commercial farms of Rubus glaucus Benth, owned byfour blackberry growers association in the provinces of Pamplona and Chitagá (North of Santander, Colombia).

Twenty two descriptors (fourteen quantitative and eight qualitative)were assessed.

The descriptors that differentiated the species and discriminated them bygroups by providing 77% of the information with the use of principal component analysis, were: length and width of central and lateralleaflets, length of flower and leaf structures, apex shape and number of secondary veins.http://revistas.javeriana.edu.co/index.php/scientarium/article/view/1798/1154Rubus glaucus Benthidentificationtaxadescriptorsprincipal component analysisconglomerate analysis |
