Comparison of Quantitative and Qualitative Yield of Olive Cultivars in North of Khuzestan Province, Iran

In order to assess the adaptability of olive cultivars in Northern Khuzestan، an experiment was conducted as a complete randomized block design with 21 cultivars in three replications. Study of flowering of cultivars showed that X-S and Doebli cultivars had 20% (lowest) and 100% (highest) complete flowers، respectively. Results of analysis of variance for quantitative traits showed that cultivar had a significant effect on all studied traits (P ≤ 0. 01). Results of combined analysis (2007-2009) also showed that the effect of year on fruit yield and oil yield/tree was significant (P ≤ 0. 05). Considering the yield and size of trees in different cultivars، the highest fruit yield was achieved in cultivars Conservalia (7549 kgha-1)، Mahzam Abu-Satl (6769 kgha-1)، Kronaieki (6239 kgha-1) and X-D (4022 kgha-1) respectively. Cultivar X-S had the highest and Valanolia had the lowest oil content /fresh weight (18. 1 and 3. 1%، respectively). Based on yield، oil content and size of trees، the highest oil yield /ha was achieved in Conservalia (723 kgha-1)، X-D (404 kgha-1)، Amigdafolia (396 kgha-1) and X-S (373 kgha-1) respectively. Based these results، Conservalia could be suggested as a double purpose cultivar in commercial olive orchards in Khuzestan due to its high yield and good conserving quality.
