摘要：

In order to ensure the genetic diversity of the Olea europaea complex, it is necessary to characterize the cultivated varieties and the wild populations. In the present study, we focused on the olives growing on two Mediterranean islands, Corsica and Sardinia. On these two islands, there are olives with many denominations, as well as forests of oleasters. Here, it was proposed to determine the relationships among cultivated and wild olives. Some Italian denominations were studied in addition to assess the influence of the mainland on the two islands in this respect. The 59 RAPD markers obtained showed the existence of many synonymous, and homonymous. A dendrogram was constructed using the UPGMA method and a FCA was carried out. The results of these two analyses showed the existence of a genetic divergence between the oleasters and the cultivated varieties. They suggest that some of the Corsican varieties were probably selected from local wild forms, contrary to the Sardinian varieties. They also show that there are feral forms growing on both islands, which result from hybridization between oleasters and varieties.
