Genetic diversity of Liriope muscari using SRAP markers / 中草药

Objective: To study the genetic diversity of Liriope muscari. Methods: The genetic diversity of 47 populations was analyzed by SRAP marker technique. Results: Fifteen primers amplified 323 polymorphic bands, and the average percentage of polymorphic bands reached to 88.47%. The average of polymorphism information content (PIC) was 0.90. Nei's gene diversity index (H) was 0.197 7 and Shannon's information index (I) was 0.319 0. Gene differentiation index (Gst) was 0.252 8. Cluster analysis using UPGMA method showed that genetic similarity coefficient ranged in 0.59-0.99. Conclusion: L. muscari shows higher genetic diversity and the majority of genetic variation occurs in populations.
