Abstract

This study focused the variability of morphological types and polymorphism level in olive tree. Ten SSR microsatellite markers and 23 morphological descriptors were used to characterize 15 indigenous cultivars of this species growing in Algeria. A significant morphological variability was observed between the cultivars. The type of the endocarp exhibited a discrimination potential higher than that of the fruit, leaf and the inflorescence. Molecular markers have also shown a very high level of polymorphism and a high discriminatory power to discriminate easily the whole sample. It is possible to achieve the same results using only 3 markers (ssrOc UADCA 18, UDO 099-043 and ssrOcUA-DCA9). These results underline the importance of using ssr markers and morphological descriptors for the inventory and identification of olive varieties.
