[Analysis of genetic diversity of 14 species of Cymbidium based on RAPDs and AFLPs].

Abstract

RAPDs and AFLPs were used to investigate the genetic variation of 14 species of Cymbidium. A great diversity was shown by 12 random primers and three primer combinations. UPGMA cluster analysis showed that the results from the RAPD and AFLP analysis were similar and the genetic distances were closest between C. ensifolium and C. sinense, C. kanran and C. faberi var. omeiense, C. mastersii and C. eburneum respectively.
