The olive tree (Olea europaea L. subsp. europaea var. europaea) is among the most symbolic and important plants specific to the Mediterranean Basin. In this study, phenological periods, crown shape, leaf characteristics, number of flowers on shoots, inflorescence length, fruit yield, fruit and kernel characteristics, and yield efficiency of ‘Şami,’ ‘Sayfi,’ ‘Saurani,’ ‘Haşebi,’ ‘Karamani,’ ‘Kilis Eblak,’ and ‘Hambelese’ olive varieties in the Adana/Kozan region were examined. In this 2‑year study, it was determined that some of the varieties are prone to alternate bearing, and each variety has different flower, fruit, and kernel characteristics. Hermaphrodite flower percentage varied between 43.93% and 90.63%. ‘Sayfi,’ ‘Saurani,’ and ‘Haşebi’ were found to be varieties with high hermaphrodite flower ratios. The results of this study may help determine varieties that may be suitable for the Cukurova region d, and may help initiate further research to reduce alternate bearing and increase yield. ‘Saurani,’ ‘Karamani,’ ‘Şami,’ and ‘Sayfi’ varieties were found to be more suitable for the region, as they yielded regular products and can also be evaluated for oil production. ‘Şami’ was the variety with the highest values for all parameters, while the ‘Hambelese’ variety had low values for all parameters but high yield efficiency. Considering the effects of global climate change, it has been suggested to create a large number of olive varieties on the basis of these characteristics.
