Abstract:
Objective To reveal the genetic relationship among populations of cultivated Coptis chinensis.Methods Twenty four populations of cultivated C.chinensis from different habitats were employed to be analyzed by the approach of sequence-related amplified polymorphism(SRAP).Systematic relationship was constructed based on the UPGMA method by Treeconw software.Results A total of 276 bands were scored,among which 120 were polymorphic bands.The average percentage of polymorphic bands was 43.48%,indicating that the materials in the test have low genetic diversity.Genetic similarity coefficients were changed from 0.877 0 to 0.951 9.By cluster analysis,the geographical distribution was not very obvious,but it was also showed some of the cultivated C.chinensis from the same region were in the same group.Conclusion Different germplasms diversity of cultivated C.chinensis population is lower and genetic background is more single.
