The Koroneiki plant is a variety from Greece, where it is also known as Koroni, Kritikia, Ladolia and Psylolia. Due to its characteristics it is a very widespread plant in its area, which occupies 50-60% of the olive-growing area. To be one of the varieties used in super-intensive plantations, Koroneiki is starting to conquer many other countries on different continents.

The low vitality and the open posture make it a very high productivity plant, with a fat yield of about 20% and with an excellent and very stable oil quality over time. For such obvious reasons the Koroneiki variety has become of great interest for super-intensive plantations. The plant is resistant to foliar maculation, while it is susceptible to tuberculosis and Verticillium. It is also resistant to drought.

Regarding its characteristics, we can illustrate:

• the leaf, elliptical in shape, with hyponastic curvature and with a smooth and pubescent under surface
• the fruit, green in color and with a slightly asymmetric oval elliptical shape
• the small, ovoid-shaped core with an asymmetrical truncated base. The surface is unequal with few fibrovascular grooves with a medium depth.
