Evaluation of Adaptability of some Olive (Olea europeae L.) Cultivars in Different Climates of Iran

To evaluate compatibility of some native and imported olive cultivars, an experiment with nine cultivars was conducted in Tarom, Roudbar, Kazeroon and Sarpolezahab Olive Research Stations since 2004 for five years. The experiment was conducted in split plot based on randomized complete block design with three replications. Some flower and fruit characteristics such as the number of flowers per inflorescence, percentage of perfect flowers, fruit weight, fruit length and diameter, flesh to stone ratio, oil percentage in dry matter of fruit, fruit yield per tree and yield efficiency were measured. Combined analysis of variance showed, significant differences in each location during five years. Significant differences were also observed among the cultivars for different traits in each location. Based on the results of five years experiments, in Kazeroon Research Station, cv. Konservolia with high yield and flesh- stone ratio was recognized as a dual purpose cultivar, and cv. Amigdalolia with high oil percentage and yield, as an oily cultivar. In Sarpolezahab Research Station, cv. Konservolia was also recognized as dual- purpose cultivar and in Tarom Research Station, cvs. Konservolia and Zard were determined as dual purpose and cvs. Koroneiki and Arbequina as oily cultivars.
