Abstract: The random amplified polymorphic DNA (RAPD) molecular marker technique was used to determine the sex of Calamus simplicifolius C. F. Wei. In the present study, DNA samples were extracted individually from 10 male and 10 female plants. After a total of 1 040 decamer primers had been tested, an approximate 500-bp male-specific DNA fragment was generated with the S1443 primer. It is feasible to identify sex at the early stages of plant life, which is beneficial for improving breeding programs of this dioecious species. In addition, we have obtained a proper RAPD protocol that is useful for other species of rattan.

Key words: Calamus simplicifolius, random amplified polymorphic DNA, rattan, sex determination.
