Objective: To investigate the genetic diversity of Ganoderma cultivars provided for the genuineness study, germ-plasm resource identification, genetic relationship study, breeding, introduction and cultivante of Ganoderma strains.
Method: With the software of NTSYSpc 2. 1, 24 materials, of G. lucidum and G. sinense, were studied using AFLP to construct the dendrogram.
Result: There were 177 polymorphic bands with 14 primer combinations. And all materials could be identified with AFLP.
Conclusion: There actually existed much genetic diversity at the molecular level among the germplasm resources of Ganoderma strains, and all the strains were clustered into G. lucidum group and G. sinense group at the similarity coefficient 0. 676.
