Most sweet cherry (Prunus avium L.) cultivars are self-incompatible and have problems of fertilization and fruit set. To produce commercial crops they need compatible and suitable pollinizers. The compatibility of “Zarde Daneshkadeh”, “Protiva”, “Sorati Lavasan”, “Haj-Yosefy” and “Meshkin Shahr” cultivars with “Shoa-o-saltaneh” as seed parent studied in a randomized complete block design (RCBD) with three replications. The compatibility of various pollens on “Shoa-o-saltaneh”, studied with two methods of controlled pollination and observation of pollen tube growth with fluorescence microscopy. The results of the controlled pollination method showed that “Meshkin Shahr” and “Protiva” cultivars are compatible and “Zarde Daneshkadeh”, “Sorati Lavasan” and “Haj-Yosefy” are incompatible. The mean of fruit set in “Shoa-o-saltaneh” cultivar using pollen grain of “Zarde Daneshkadeh”, “Protiva”, “Sorati Lavasan”, “Haj-Yosefy” and “Meshkin Shahr” were 0, 4.2, 0.2, ,0.4 and 15.7 percent respectively. The results show that sweet cherry cv. “Shoaosaltaneh” is a self-incompatible cultivar (fruit set = 0) and it needs compatible and suitable pollinizers for fruit set. The microscopic examination of pollinated flowers showed that pollen tube of “Meshkin Shahr” cultivar reached to the ovary in 96 hours after pollination. These observations confirm the results from field controlled hybridization.
