Analysis on genetic diversity of Trichosanthes kirilowii based on ISSR / 中草药

ABSTRACT

Objective: In order to provide the foundation for the genetics and breeding of Trichosanthes kirilowii, the genetic diversity of T. kirilowii was analyzed. Methods: Studies on polymorphism and cluster on 34 T. kirilowii materials from different growing areas were done by inter-simple sequence repeat (ISSR). Results: The genetic polymorphism of T. kirilowii was up to 90% from different growing areas. According to the results of ISSR culster, the materials of T. kirilowii were divided into three classes food seed, edible and medicinal, and wild types. Conclusion: There is higher genetic polymorphism among T. kirilowii materials, and no correlation to the growing areas.
