It is mainly grown in western Crete and southern Peloponnese. In Crete there are numerous trees with age of thousands of years still producing fruit. It accounts for 15-20% of the country’s olive growing acreage.

Its start of bearing and time of flowering are intermediate. Its productivity is medium and alternate. It is mainly cultivated for olive oil production. It has a high fruit oil content and excellent quality oil (Metzidakis). It is also used for pickling green and salted black olives. It is resistant to cold and moderately tolerant to dry climates and salinity (Chartzoulakis 2005). In addition, it is less susceptible to olive knot, but susceptible to olive leaf spot, olive fly (Kalaitzaki et al.) and verticillium wilt (Markakis et al., 2022). ReferencesChartzoulakis K.S. 2005.
