The objectives of this study were to reveal DNAs (RAPD) individual variation and to analyze
the genetic and geographical diversity of Fraxinus ornus populations from Serbia. PCR-RAPD
variation was examined in three natural populations (90 trees) and the data analysed with genetic
softwares (POPGENE, Arlequin and TFPGA) for obtaining parameters of genetic diversity
and structure. PCR-RAPD markers reveal individual variation in F. ornus. A total of 122 fragments
were amplified using 7 primers and of these 77 (63%) fragments were polymorphic. The
mean gene diversity for all populations was 0.27 and the Shannon’s index was between 0.38
and 0.42. The partition of total genetic variance indicates a relatively restricted population differentiation
as expected in outcrossing species. Present and future information on genetic structure
and variability in F. ornus needs to be incorporated into strategies for the preservation of
genetic resources of tree species.
