Abstract
This experiment was carried out to determine the adaptation ability of 12 olive cultivars in the dry-warm climate of Kermanshah province, Sarpol-e-Zehab Dallaho olive station from 2007 until 2009. A randomized complete block design with three replications was used. Vegetative and reproductive traits were evaluated according to I.P.G.R.I. and I.O.O.C. descriptors. Flora emergence was significantly different over years and between cultivars. Mastoidis, the late ripening cultivar, produces small fruits (1.2 gr/ fruit) with highest level of oil per fresh matter (12.8%). Jolt was early ripening cultivar and showed the highest single fruit weight (5.4 gr/ fruit) and the lowest content oil per fresh matter (4.9%). Frangivento and Mavi cultivars had the highest (3360 kg/ha) and the lowest (873 kg/ha) yields respectively. Finally, Jolt, the table olive in early ripening cultivar and Mastoidis, the oil olive in late ripening cultivar were better than others. Temperature played a major role in delay of flowering by affecting phonological state and development of flowers. Oil content in olive was affected by environmental conditions and genetic backgrounds of cultivars.
