Description

Olea europaea 'Koroneiki' is a highly prized, early-bearing olive cultivar native to Greece, celebrated globally for its exceptional oil quality, high and consistent productivity, and adaptability to various climates and soil conditions . This vigorous, medium-sized evergreen tree forms a rounded canopy with a characteristically spreading growth habit and sparse density, making it well-suited for both traditional and modern high-density hedgerow plantations . It is known for its small, elliptical-lanceolate leaves and produces small fruit that, although low in individual weight, are remarkably rich in oil with a very high oleic acid content and excellent stability . While it shows moderate resistance to leaf spot and verticillium wilt, it is very susceptible to olive knot, requiring careful monitoring . Distinguished by its self-fertility and early flowering, it comes into bearing early, producing small but abundant fruit .
