Abstract：In this study, the genetic diversity of nine populations of Rhyacionia leptotubula in Northeast Yunnanwas analyzed by using mitochondrial COІ and ND5 genes as molecular markers. Genetic variation between these populations was also explored. The results indicated that COІ and ND5 genes showed low intraspecific genetic diversity. Phylogenetic tree and median-joining network showed that the populations grouped into two clusters. One consisted of the samples fromRedLand, Dongchuan and Lao Ma Yi Gu, Xundian, the other included the remainders. Molecular variance analysis demonstrated that about 80% of the variation came from between the clusters, which indicates a clear differentiation among populations.
