In order to study adaptation ability of 15 commercial olive cultivars, this experiment was carried out using a randomized complete block design with three replication during the period from 2007 to 2009 in dry-warm climate of Sar-pol-e-Zehab Dallaho olive station of Kermanshah province. In this experiment, vegetative and reproductive traits were measured according to I.O.O.C. descriptors. Flora emergence was significantly different over years and among cultivars and flowering period appeared from end March to early May. Korneiki, as the late ripening cultivar, produced the smallest fruits (0.59 gr/fruit) among other cultivars. The highest fruit set, dry matter and content of oil accumulation (12.1%, 12.2%) in fresh matter were recorded in Amphisis and Korneiki cultivars, respectively. Mary was early ripening cultivar and it had the least dry matter and oil in fresh matter (5.2%). Conservalla cultivar had the most fruit weight (4.2 gr/fruit), flesh and yield per hectare (6700 kg/ha). On the other hand, the least percentage of fruit set and yield was obtained in Gorgan1 genotype (720 kg/ha) and Roghani Roodbar cultivar (637 kg/ha). The results indicated that temperature played a major role in delay of flowering by affecting phonological statue and development of flowers. It also oil content in olive affected by environmental condition and genetic background of cultivars. Finally, Olive Table cultivars (Conservalia, Manznilla and Sivillano), Zard-e- ziton (Dual-Purpose) and Oil Amphisis cultivar were better than the others for Sar-e-Pol-e- Zehab weather conditions.
