[RAPD analysis on germplasm resources of different farm races of Morinda officinalis].
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.


CONCLUSIONS
There actually existed much genetic diversity on molecular level among the different farm races of Morinda officinalis.
