| Abstract:
One-hundred-ninety RAPD fragments generated by the 46 selected primers were analysed for the study of genetic relatedness among Mediterranean and Iberian olive zones based on their geographic proximity. The study included 51 olive cultivars from nine Mediterranean countries (Algeria, Greece, Italy, Morocco, Portugal, Syria, Spain, Tunisia and Turkey). The data were elaborated using Chi-square distance defined by Benzecri (1970) and UPGMA clustering method. Factorial Correspondence Analyses were also applied for both Mediterranean and Iberian olive zones. The dendrograms obtained for these zones showed a tendency of clustering according to the geographic origin of the cultivars. Factorial Correspondence Analyses corroborated the above-mentioned results. These results agree with the hypothesis of the autochthon origin of olive and their limited diffusion out of their original zones. | |
