Abstract: 39 accession of 11 species and 3 varieties of Cymbidium in Yunnan Province were analyzed in similarity by using RAPD technique . Subgenus Cyperorchis, such as C. hookerianum, C. tracyanum, C. erythraeum, and C. lowianum are
clustered into a clade ; Subgenus Jensoa , including C. kancan , C. sinense, C. pumilum, C. faberi , C. goeringii, C. goeringii var. serratum, C. tortisepalum var. longibracteatum, C. tortisepalum and C. cyperifolium var . szechuanicum are classified into another clade . C. lancifolium is closer to subgenus Jensoa than to the others . C. tortisepalum var . longibracteatum is close to C. tortisepalum var. tortisepalum and both of them are far from C. goeringii . It is not supported that C. cyperifolium var. szechuanicum belongs to a variety of C. faberi . These findings may benefit to Cymbidium breeding.
