Abstract: Thirty-eight species of Dendrobium were analyzed phylogenetically using AFLP technique. Eight pairs of primers combination were screened from 64 pairs of primers combination and generated 1 644 amplified loci, 1 639 of which were polymorphic loci which accounted for 99.7% in the total amplified loci. It showed that the generation diversity standard of Dendrobium was very high in our country. Cluster analysis showed that Sect. Dendrobium and Sect. Formosae did not form an independent branch, Sect. Aporum and Sect. Strongyle were consisted of a common branch. They had a lower similarity with another section. Sect. Grastidium, Sect. Stachyobium and Sect. Stuposa formed an independent branch. They had a different evolution direction. Genetic relationship in domestic Dendrobium was much more complicated, and they were not a monophyletic group in nature, but a paraphyletic or polyphyletic group.
