One of the problems in growing olive trees is pollen-incompatibility. This study was conducted in Gorgan climatic condition to determine the self-incompatibility of olive cv Koroneiki and to select the suitable pollenizers. Randomized complete block design with three replication (trees) and six treatments including open pollination, self pollination, Mission, Conservalia, Sevilana and Valanolia were used. To study the effect of flower emasculation in such studies, another experiment was conducted after emasculating the flowers before blooming. The results showed that Koroneiki was self-incompatible. It was incompatible with Valanolia and partially compatible or compatible with Mission, Conservalia and Sevilana. The study also showed that emasculating the flower did not have any effect on the obtained results and is not necessary in such experiments. The study of quantitative traits showed that there was a considerable variation among the cultivars.
