Abstract: Single Nucelotide Polymorphisms (SNPs) have become the most widely used markers in many current genetic applications. Here we report the discovery of nine new SNPs in olives by direct partial sequencing of two genes (OEX and OEW) in sixteen Tunisian cultivars. The SNP markers were then used to genotype 24 olive cultivars and assess the level of genetic diversity. Power of discrimination of SNP markers was then compared to that of microsatellites (SSRs). A combination of SSR and SNP markers was finally proposed that can be used for cultivars identification in juvenile step or for oil traceability.
