RAPD (Random Amplified Polymorphic DNA) analysis was conducted to Schisandra nigra plants in order to select the specific markers for monoecious and dioecious individuals. RAPD results using eighty random 10-mer primers revealed that S. nigra had a different banding pattern from S. chinensis and Kadsura japonica. When DNA isolated from leaves of monoecious and dioecious plants were used as PCR template, only five primers, OPA-17, OPA-19, OPB-03, OPB-09 and OFB-16, showed polymorphic band patterns. No variation in banding profiles within male or female individuals was observed when these five primers were used whereas three monoecious plants (No 1, No 2 and No 3) showed different banding patterns one another, A 750 bp segment was amplified by primer OPB-3 from male individuals. On the other hand, two segments, 950 bp and 1690 bp, with OPA-19 and 700 bp of segment with OPB-3 were amplified in female individuals. These result indicate that the specific buds of male and female S. nigra could be used as genetic markers for the early discrimination of male and female individuals.
