Abstract: | One hundred and two olive RAPD profiles were sampled from all around the Mediterranean Basin. Twenty four clusters of RAPD
profiles were shown in the dendrogram based on the Ward’s minimum variance algorithm using chi-square distances. Factorial
discriminant analyses showed that RAPD profiles were correlated with the use of the fruits and the country or region of origin
of the cultivars. This suggests that cultivar selection has occurred in different genetic pools and in different areas. Mitochondrial
DNA RFLP analyses were also performed. These mitotypes supported the conclusion also that multilocal olive selection has occurred.
This prediction for the use of cultivars will help olive growers to choose new foreign cultivars for testing them before an
eventual introduction if they are well adapted to local conditions.
