Abstract

Genetic diversity of twelve accessions of Strobilanthes tonkinensis was evaluated by RAPD.The results showed that 305 bands were amplified by 41 random primers,among which 120 were polymorphic,accounting for 39.34% of the total bands,which revealed a low degree of genetic diversity among the twelve accessions.The genetic similarity analysis demonstrated that their genetic similarity coefficients were between 0.734 4 and 0.963 9.The phylogenetic dendrogram with UPGMA revealed that the twelve accessions could be divided into two clusters I and II(D=0.821).More over,the germplasm resources coming from the same geographic area presented closer relationship in phylogeny.
