Objective: To screen the AFLP primers with good diversity to distinguish various species of Cannabis.
Methods: The AFLP was used to analyze the genetic diversity of 12 species of Cannabis using 55 primer combinations.
Results: A total of 285 AFLP bands were obtained using five primer combinations with better diversity, among which 99 bands were polymorphic and 10 bands were special, with 47-76 bands amplified in each pair of primers.
Conclusion: AFLP may has good resolution in the diversity study of Cannabis. It may provide an essential basis for further study of the genetic diversity of Cannabis.
