Abstract:
Intersimple sequence repeats (ISSR) molecular fingerprinting markers have been employed to authenticate eight populations of Dendrobium officinale using 10 primers selected from 76 ISSR primers. A total of 127 DNA fragments were amplified, of which 115 were polymorphic (90.5% of all bands). Sixteen specific authentication markers have been found. To enhance the efficiency of authentication, ISSR fingerprinting codes have been constructed using six polymorphic bands for authenticating D. officinale populations. Eight wild populations of D. officinale have been authenticated accurately using ISSR.
