From the most years olive cultivation has been practiced in Iran, and the current, the area of cultivation is 35,000 hectares. In addition, olive consumption as canned olives is also important in terms of making oil. Per capita consumption of olive is about 30 grams in Iran. In the majority of fruit trees pollination is a necessary condition for fruit set. Therefore, determination of suitable pollinizer cultivars needs to olive orchards.Pollen types used can be effective on quantitative and qualitativecharacteristics of olive fruit. The blooming, inoculated flowers and flowers abscission in the different varieties of olives are the mostissues affect in productivity and quality olive fruit. Also infertility problem, self-fertility and cross-fertility in an olive cultivars important issues that have an impact on the quantity and quality of fruit and play an important role in product performance. Thus, identifying suitable pollinizer can be a step toward economic development in the olive production. This paper todetermine the best pollinizer varieties for olive tree cv Dacal in a randomized complete block design with seven treatments and three replications was conducted in Olive Research Station in spring 2012-2013 . Emasculatedflowers of Dacal cultivar pollination with open –pollinated, cross -pollinated by pollen of cultivar such as Mygdalvlya, Fyshmyroudbar , Knsrvalya,Dgrgrdh and their pollen mix. Traits measured including fruit length, fruit diameter, fruit weight, fruit volume, seed length, seed diameter, seed weight, seedvolume, pulp weight, the fruit yield and the percentage fruit set. The results showed that olive trees are Self-Incompatibilityand pollen of olive varietieAMygdalvlya the best for it
