Investigation of self-productivity in some olive cultivars grown under Antalya ecological conditions

Irregular fruit yield in olives is caused by ecology, cultural processes as well as self-inefficiency and not choosing suitable pollinators. Since the self-productivity of olive varieties in different growing areas, this research was carried out to determine the productivity of 'Gemlik', 'Manzanilla', 'Memecik', 'Nizip Yağlık' and 'Tavşan Yüreği' with high commercial value. Selfing and natural pollination were determined in the Akdeniz University Faculty of Agriculture Research and Application Field in Antalya. In self-pollination, the flowers on the clusters were placed into cloth bags at the balloon stage, the pollen was poured into the pouch at the time of flowering, the pouch mouth was closed with a rope and the pouch was shaken to pollinate. Significant differences were determined in % fruit set rates obtained in varieties as a result of selfing and natural pollination. In all olive cultivars used in the experiment, the percentage of fruit obtained from free pollination was higher than self-pollination. 'Gemlik' and ‘Tavşan Yüreği' were found to be self-fertile, 'Memecik' and 'Nizip Yağlık' were found to be partially productive, and 'Manzanilla' were found to be self-inefficient. The highest fruit set in both free and selfing was determined in the 'Tavşan Yüreği' cultivar.
