Abstract:
Objective To analyze the hereditary background of common species from Rhodiola L. in Yunnan Province. Methods Fifty-nine samples of six populations in three natural medicinal species from Rhodiola L. were studied by RAPD method. Results The percentage of polymorphic bands (PPB) of three populations from R. crenulata were 37.97%, 46.15%, and 39.45% respectively; the Nei's gene diversities (h) were 0.110 3, 0.143 7, and 0.137 1, respectively; the Shannon's information indes (I) were 0.173 6, 0.222 1, and 0.206 7, respectively; at the special level, the PPB was 70.47%, I was (0.258 3); the genetic differentiation (G_(st)) was 0.263 0. The PPB of two populations from R. fastigiata were 43.67% and 44.42%, I were 0.215 3 and 0.217 4, respectively; at the special level, the PPB was 65.51%, G_(st) and I were 0.313 2 and 0.313 9, respectively; the PPB of R. yunnanensis was 36.97%, I was 0.188 1. Conclusion RAPD molecular marker could be used to molecular authentication and genetic diversity analysis of medicinal species from Rhodiola L.
