Genetic diversity analysis of Tunisian olive cultivar by SNP markers

Abstract

To study the genetic diversity of 17 olive tree cultivars (Olea Europaea L.) sampled from different Mediterranean regions, we screened three SNP markers (ACP-1, ANTHO3, SOD) located in three different genes. The genotypes of the sampled cultivars were depicted via the genotyping analysis. The dendrogram based on cultivar genotypes generated by SNP markers revealed three clusters which were consistent with the established classification. In addition, we compared the results obtained with agro-morphological and chemical data using bioinformatic analyses. This work offers a more relevant classification of the genetic classification of the Tunisian olive cultivars.
