Abstract:

In this paper, the genetic diversity of 14 cultivation strains of Wolfiporia cocos were analyzed by using the molecular labeling technique of RAPD to study their genetic relationship. 9 RAPD random primers were used in the amplification and 4 of them produced 21 relative obvious DNA bands. The strains were clustered base on the 21 DNA bands and a dendrogram of 14 W.cocos cultivation strains was obtained. The results showed that 14 W.cocos strains could be divided into 2 groups at the similarity coefficient of 53% ;while at the similarity coefficient of 93%, the strains were divided into 13 groups.
