| Abstract: | The genetic variation within and among seven Tunisian natural Hypericum humifusum L. populations belonging to three bioclimatic zones (sub-humid, upper semi-arid, and lower semi-arid) was assessed using
random amplified polymorphic DNA markers. Eight selected primers produced a total of 166 bands, of which 153 were polymorphic.
The genetic diversity within a population, based on Shannon’s index and percentage of polymorphic loci, was relatively high.
The level of variation among populations did not differ significantly. However, the variation among populations grouped according
to their bioclimates was significant. |
