An assessment of the genetic diversity and variation of finef lin ternata collected from 43 populations in China was undertal‹en using SRAP +TRAP marl‹ers. A total of 13 SRAP primers in addition to 3 TRAP primer combinations yielded 292 bands in total of which 286 were polymorphic (98.0$), with an average of 16 for each. The PIC value ranged from
0.88 to 0.95, with a mean polymorphic information content (PIC) of 0.92 over all the primers. A cluster analysis was conducted based on the unweighted pair group method with arithmetic average (UPGMA), and a principle coordinate analysis (PCA) was per- formed relying on Nei’s genetic distance, both of which showed similar outcomes in that the results of clustering did not correlate to the geography locations but showed an as— sociation with morphology. An analysis of molecular variance (AMOVA) was performed to detect the source of variation; the results indicated that the main variation existed within populations (67.2 ), whereas there was still 32.8$ differentiation existing among the populations
