Agronomic characterisation and commercial considerations

The variety can be easily distinguished by the typical formation of a nipple on the fruit apex. Fruits mature between mid-November and mid-December. It is highly resistant to drought (Uluçay, 2020). For this reason, it is recommended in the areas where irrigation is not available. It is moderately resistant to cold. It grows strongly under good care conditions. Although it shows periodicity, its yield is satisfactory. Rooting ability of cuttings is at medium level. It is partially self-fertile. Full flower rate is at medium level. Its pollinators are Ayvalık, Izmir Sofralık, Çakır, Gemlik, Erkence and Memeli (Çavuşoğlu, 1980). Since it has a high oil content (22%<), it is primarily used for oil production, however it is consumed as green and black table olive as well. Total phenolic content changes between 296-407 mgCAE/kg depending on the maturation stage (Köseoğlu et al.2016) and the level of α-tokoferol is determined between 219-324 mg/kg (Sevim, 2021). The oil is of a balanced profile of fruity, bitter and pungency attributes in addition to the long shelf life.The number of fruits per kg is approximately 220, the flesh/pit ratio is 6.7 (Kaya et al, 2015).
