- Characterization of date palm (Phoenix dactylifera L.) cultivars is valuable for breeding programs, and conservation purposes. It is a complex task using morphological traits alone, however DNA marker such as simple sequence repeat (SSR) can complement and enhance the discriminatory power of morphological traits. Nine morphological traits and fourteen SSR loci were used to study morphological and genetic diversity of three elite date palm cultivars ('Khalas', 'Shishi' and 'Khnaizi') in Qatar. Analyses of variance of the morphological data reveal significant differences among the date palm cultivars. Moreover the data obtained from SSR markers examined in principal coordinate analysis (PCoA) enabled the samples of the three date palm cultivars to be classified into three groups according to their genetic variation.
