Abstract

The study was conducted on some local olive varieties i.e. Al Beareny (♀) and Al Gellet (♀), and on some foreign olive varieties i.e. Al Zorzalina (♂), Al – Frantoio  (♂) and Picholine (♂), where grown in the genetic complex in Homs Agricultural Research Center, during 2016/2017, to study the effect of hybridization of the studied olive varieties on the qualitative and quantitative characteristics of fruits and seeds, and to determine the best pollinator of the studied varieties, besides to study the incompatibility of each olive variety. According to the cross-pollination between olive varieties i.e. Al Beareny(♀), AlKaissi(♂), Al Zorzalina (♂), and Al – Frantoio  (♂), the results showed that there were some changes in qualitative traits (fruits and seed shape), besides some quantitative changes (fruit and seed weight). It was noticed that self-compatibility of Al Beareny variety was partial. AlKaissi, Al Zorzalina and Al – Frantoio varieties cannot be used as good pollinators for Al Beareny. The results also exhibited the effect of hybridization Al Gellet (♀) variety with Picholine (♂) and AlDan (♂) on the quantitative traits of fruits and seed compared to the qualitative traits which did not influenced. Moreover, the self-compatibility of Al Gellet also was partial, and Picholineis is considered a good pollinator of AlGellet variety, while AlDan cannot be used as a good pollinator for Al Gellet.

Key words: Olea europaea L. Cross-pollination, Pollinator, Self-compatibility.
