Abstract

The Egyptian olive industry requires new selected genotypes to address the need of modern production. In order to produce new genotypes for table olives, olive oil, or dual purpose varieties, breeding program was initiated in Egypt in 1994, by crossing between local and foreign cultivars. During three years  progenies from crosses between cvs. (Chemlali x Aggizi), (Aggizi x Kalamata) and (Aggizi x Koronaiki) were evaluated. The progenies have been analyzed for traits of the tree (shoot length, shoot thickness, number of nodes/shoot, internodes length (cm), the leaves (average number of leaves/shoot, leaf surface area, leaf shape) , flowering ( flowering time , the length of inflorescence ,  number of total flowers/inflorescence, number of perfect flowers/ inflorescence, number of staminate flowers/ inflorescence,  sex ratio, and fruit set/m,), fruiting (production, fruit shape, fruit weight, stone weight, flesh weight ,flesh/stone, moisture and oil content( oil percent in fresh weight and oil percent in dry weight) and rooting ability .From the obtain data  it can be concluded that some valuable selections have been resulted. Such Progenies were No.24 ,26, 27and 31 for table olive; progenies No  7, 10, for oil and No. 33, 38, 39 for dual purpose. Conclusion Thus, all the best selected progenies were propagated and planted in three locations, to evaluate their performance in different geographical areas. Performance included i.e., tree growth, yield, fruit characteristics, oil content and oil compositions in fatty acids. There comes the necessity to study quantitative and qualitative traits of olive production.
