| Abstract: | AFLP markers were used to analyse the intra- and interspecific relationships among 22 natural populations of 13 Patagonian species of Berberis and the relationships among the taxa belonging to homoploid and polyploid complexes. Seven primer combinations gave rise to 231 AFLP bands, of which 199 were polymorphic. Correspondence between AFLP data, morphological traits and seed protein bands was also assessed. The dendrogram inferred from AFLP fingerprints showed that, in general, populations of the same species formed closely related groups with high coefficients of similarity. Principal co-ordinates analysis showed two separate subgroups: (i) B. bidentata and their putative ancestors –B. darwinii and B. linearifolia– which form a homogamic group, and (ii) B. buxifolia, B. heterophylla and B. parodii– which could form a polyploid hybrid complex.
