Abstract:
Objective To analyze the genetic diversity of eight species of Caragana Fabr. in Ordos Plateau. Methods To study the genetic diversity of the eight species with ISSR method. Results The total percentage of polymorphic bands (PPB) of the eight species was up to 100%, which was extremely high and showed an abundant genetic diversity. However, the genetic diversity of different species was not the same. The genetic diversity of C. tibetica, C. korshinskii, C. stenophylla, C. roborovskyi, and C. intermedia was higher, while that of C. opulens and C. purdomii was lower, and that of C. brachypoda was the lowest. The analytic results of the Nei′s gene diversities and the Shannon′s information index were similar. Different species could be differentiated through UPGMA method and characteristic banding pattern of ISSR. Conclusion ISSR Molecular marker could be used in molecular authentication and hereditary background study of the species of Caragana Fabr. These results provide the scientific basis of developing effective protection measures for these species.
