As the climatic change has a direct effect on olive trees productivity and negatively affects olive manufacturing process in Egypt. So, it has become necessary to re-evaluate the cultivars which are more resistant to climatic conditions especially local cultivars and selected new olive genotypes to achieve a distinguished competitive in entering global markets.  For this reason, three of local olive cultivars (Toffahi, Aggizi Shame and Aggizi Akse) that appears tolerance to climatic conditions were selected to re-evaluate with seven genotypes (G102, G97, G67, G55, G54, G24 and G16) produced from the project of “Genetic improvement of Olive” (CFFC) IOC. The present investigation was conducted during two successive seasons (2022 and 2023) to find out the most important characteristics of these cultivars and genotypes and selecting the most superior ones in fruit quality and productivity, which meeting the international market requirements and are suitable to expand in the new regions. The genotypes and cultivars have been analyzed according the methodology for primary characterization of International Olive Council. The results indicated that, all tested genotypes are classified as a table olive and compete in their characteristics of flesh weight and flesh/stone weight ratio with the other common table cultivars. Whereas, G97, G102 and G55 were the highest genotypes in the industrial parameters and sensorial characteristics which means the recommendation to expand their cultivation especially with the declined production as a result of the climate changes.
