Different olive cultivars in term of pollen compatibility are categorised to the four following groups : (1) Self-fertile cvs or self compatible , (2) Partially Self-fertile cvs (3) Self-sterile cvs or Self incompatible (4)Andro-sterile cvs or Male sterile cvs. Therefore cross pollination is necessary for the last three groups for commercial production. The main objective of this study is determining types of pollination in Zard, Amygdalifolia, Mary and Calamata cultivars. This research arranged in Randomized Complete Block Design (RCBD) with four replications. on each tree in different four-sided is selected 40-60 flowering branches with 30-40 centemeter lenght, when flowers are become showen and bulge white , flowers were isolated with paper bags. In order to, study of Self- Pollination , half the number branches until end of full bloom is isolated and other branches were open pollinated. Performance measures include first and final friut-set and fertile and compatibillty index. Fruit numbers were acounted four stages (form intial fruit set to harvest). The results two years average showed that mean final friut set for Zard, Amygdalifolia, Mary and Calamata cultivars in the self-pollination were 17.18, 9.56, 13.38, 11.58 and in the open pollination 28.58, 19.52, 16.67, 13.94 percent respectively So rate self fertility index were 0.767, 1.679, 2.035, 1.803 and compatiblity index 0.799, 0.832, 0.601, 0.523. Therefore with compration average by T-test, Self-Fertility index and compatiblity index in the Roudbar condition Zard and Amygdalifolia cultivars were been partially self fertile group, Mary and Calamata cultivars were been self fertile group.
