The most cultivated olive oil variety in Tunisia “Chemlali Sfax” has low oleic acid level and high palmitic acid level. In order to resolve this problem, a genetic improvement program throught controlled crosses between Chemlali Sfax and other Tunisian and foreign varieties was started in 1993 and had generated a collection of 1200 hybrids. The aim of this study is to characterize two selected hybrids on the morphological, agronomic and oil quality plans (Hd1= Meski/Chemlali Sfax and Hd2 = selfpollinated Chemlali Sfax). Morphological characters showed a wide variability. Also, the results of tolerance to Verticillium showed that the average infection rate of Hd2 hybrid (48.46%) is significantly lower than that of the hybrid Hd1 (76.08%). Moreover, the acid composition of both hybrids was more interesting. In November, palmitic and linoleic acids concentrations for Hd2 were low (11.5 and 14.1%), while the oleic acid concentration was high (70.5%) as compared to the hybrid Hd1 (65.3%). Thus, the database analysis revealed that the plant material was clustered into two main groups according to the year. Consequently, the principal component analysis generated two principal compounds which accumulated 91.1% of the total variance.
