Koroneiki i-38 This is a Greek variety originally cultivated on the plains, lower hillsides and coastal areas of Crete where the climate is relatively warm. It adapts well in high-density orchards and comes into production early (second leaf). The fruit is very small with excellent oil quality that expresses a sweet and fruity flavor. The yield is high and production is consistent year to year. Harvest time is approximately the second week of October. Arbequina IRTA® i-18 This is a clonal selection of the Arbequina Standard. The i-18 clone has a more erect growing habit and higher yield efficiency than the Arbequina Standard. It has a heavier initial bearing habit, more uniform ripening and a generally higher overall production. Arbosana® i-43 This variety has low vigor and high productivity. It has an open growth habit as compared to the Arbequina Standard. The fruit is small and the oil quality is good. It is tolerant to verticilium but susceptible to leaf spot and iron-induced chlorosis.               Arbequina Standard More than 100 olive varieties have been tested for high-density systems and Arbequina is one of the best fits. The variety is very precocious and will begin bearing in the second year. The fruit is small and the oil quality is excellent. The tree vigor is low which makes it a perfect fit for a high-density system. The variety is tolerant to leaf spot, verticilium and is resistant to cold temperatures. It is susceptible to iron induces chloroses in calcareous soils.
