- Abstract : Management of ex situ olive collection is crucial for suitable genetic resources conservation. This study aims to complement characterization of olive accessions belonging to the National olive germplasm collection located in the south of Tunisia. The morphological characterization of endocarp of 22 Tunisian cultivars was made. Multiple component analysis (MCA) showed 5 different groups of cultivars and one case of synonymy. A set of six Simple Sequence Repeat markers (SSR) were used to fingerprinting the cultivars studied. The total number of alleles was 44 with a mean of 7.33 alleles/locus. The polymorphism information content (PIC) varied from 0.45 for DCA 03 to 0.85 for DCA 16 with a mean of 0.7. The Principal Component Analysis (PCoA) was used to cluster cultivars. We assume the power of the microsatellite markers and the phenotypic richness of our local germplasm in Tunisia.
