The genetic diversity of wild olive trees sampled from the seven oldest different trees from the Jabal Al-Akhdar region, at Albayada (Alwardya, Belhaded and Alhejab)- Libya, was evaluated using agro-morphological characters. The aim of this study is to determine morphological characters of the seven oldest wild olive trees (unknown genotypes). High significant variation among various trees was detected. The characters which were measured such as, mean number of fruit/kg, mean of fruit weight, size and shape, flesh thickness, and weight, and humidity percentage. The stone weight, shape, fruit flesh/stone ratio. Fruit oil content was measured as weight and dry matter for both wet and dry matter. These data sets were used to morphologically identify and desirable Libyan wild types, which were used to discriminate between use of fruit (oil, table or dual-purpose) as well as this research demonstrates that wild Libyan types have unique characteristics that differentiate them from imported varieties.
