Cluster analysis resulted in grouping of the 40 accessions ]of Rosa damascena] into nine distinct genotypes..... The main group consisted of 27 landraces that showed the same microsatellite profile. This group included all accessions from the main rose oil production sites of Damask rose in Iran [Isfahan]. The pattern of this group was identical to that of an accession from Bulgarian production areas. Rusanov et al. showed that all Bulgarian Damask roses are this genotype...

The accessions from Fars province formed two distinct clusters in the dendrogram. They are from an environmentally
very distinct region, far to the South of Iran. One of these samples was hexaploid, while all other samples were tetraploid, as expected for R. damascena.....Except one plant, all genotypes identified here were tetraploid, consistent with the general literature. One plant was hexaploid. At this moment, we do not know whether this is the first of more hexaploid R. damascena plants. It may be misclassified, but cuttings from all plants have been evaluated by several experienced taxonomists after cultivation for 2–3 years in a common garden.
