© 2016 The Journal of Horticultural Science & Biotechnology Trust.Iran is considered to have a unique gene pool of different fruit and nut species including olive (Olea europaea L.). In this study, we used 22 previously developed microsatellite (simple sequence repeat; SSR) markers for olive to evaluate the level of genetic variation and to produce identification keys for 63 Iranian accessions of olive belonging to 17 groups of cultivars. Based on morphological features, the number of flowers per inflorescence, fruit weights, endocarp weights, oil percentages, and flesh weights per endocarp had the highest coefficient of variation values, indicating the large extent of morphological variability among the 63 Iranian olive cultivars studied. All 22 microsatellite (SSR) markers revealed a high level of polymorphism, with a mean polymorphic information content (PIC) value of 0.511. Analyses of genetic structure among the 63 olive accessions were carried out using modelbased methods, which showed a tendency for geographical clustering. Ten SSRs out of the 22 were successful for the identification of unique ID keys for 52 of the 63 accessions. In most cases, there was disagreement between the molecular data and the morphological data. These results could be used to reconstruct and maintain a collection of olive for future breeding programmes.
