Objective:
To explore the genetic diversity of different farm races of Morinda officinalis on molecular level.
Methods:
The molecular biological technique-random amplified polymorphic DNA (RAPD) were used.
Results:
Of the 40-mer arbitary primers, 14 were found to amplify polymorphic products. 3-5 polymorphic bands were amplified by each polymorphic primer on the average. Using UPGMA method all the tested accesions can be clustered into two groups: 4 accessions of Daye were classified as one group, 1 accession of Xiaoye be another group.
Conclusion:
There actually existed much genetic diversity on molecular level among the different farm races of Morinda officinalis.
