Abstract: Three regional populations (Hankou :CP-1 ,Hanyang :CP-2 ,Wuchang :CP-3) of Cachesium polypinum in Wuhan were analysed using randomly amplified polymorphic DNA ( RAPD) technique. Based on RAPD data , the pairwise genetic similarity of the three populations were 0.6921 on average , ranging from 0.6522 to 0.7385. The genetic similarity (S) between CP-2 and CP-3 was the greatest ,and S between CP-1 and CP-3 was the least . The relationship between variations and environment , and the significance of RAPD analysis of genetic diversity of Cachesium polypinum were discussed.
