Abstract

As part of the protection of Olive biodiversity and enhance its role in protecting areas of high risk of erosion, we have study the genetic diversity of twenty two accessions of olive in the region of Hbebsa. The experimental approach was based on 29 morphological parameters as recommended by IOC (1997) and the study of oil (composition, content and quality) extracted from the 22 different accessions. We have noted a significant fluctuation of the flush percentage (from 40.62 to 88.49%), the fruit weight (from 0.28 to 4.48 g) and the endocarp weight (from 0.14 to 0.68g). The morphological study permitted a specific description of the characteristics for the tested accessions and their repartition into three groups. Olive oil content is high for all studied accessions, especially for the accession 3 with approximately 28.95%. The oil quality of the different studied accessions is classified as extra-virgin oils with high oleic acids and low palmitic and linolenic acids. In conclusion, the results have proved the wealth and the importance of the olive germplasm although the desertification of the studied site. These findings were of interest to protect the specimens studied accessions.
