Botanical/commercial classification:

Latin name—Olea europaea L.

Common name—Olive tree.

Varietal denomination: ‘I-15’.


This application claims priority to Plant Breeders' Right Application Number 2018/1938, which was filed at Community Plant Variety Office in the European Union on Jul. 25, 2018, the contents of which are hereby incorporated by reference for all purposes.


The new variety of olive tree of the present invention was created by a controlled cross in Spain wherein two parents which previously had been studied were crossed in the hope that they would contribute the desired characteristics. The female parent (i.e., seed parent) of the new variety was the ‘ARBOSANA’ variety (unpatented). The male parent (i.e., pollen parent) was the ‘KORONEIKI’ variety (unpatented).

The parentage can be summarized as follows:

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

The new variety has the same productivity of the ‘Arbosana’ variety and more than 5 point (%) of oil content. The new variety has a good quality of olive oil that is comparable to the olive oil of the ‘Koroneiki’ variety. The new variety ripens 1-2 months earlier than the parent varieties ‘Arbosana’ and ‘Koroneiki’ with a very good yield efficiency. The new variety's growth habit has a low vigor and compact form, as seen in the ‘Arbosana’ variety. The non-parental variety that the new variety is most similar to is the ‘Arbequina’ variety. The new variety's low vigor is less than the ‘Arbequina’ variety, which is ideal for mechanical harvest. The new variety's ripening is at the same time as the ‘Arbequina’ variety. The new variety has a more than 5 point (%) of olive oil content and the ‘Arbequina’ variety has more than 3 point (%) of olive oil content.

It was found that the new variety of the present invention possesses the following combination of characteristics:

    • (a) forms an upright to spreading growth habit, and
    • (b) produces fruit with medium weight, which are colored black at full maturity.

The new variety well meets the needs of the horticultural industry.

The new variety can be readily distinguished from related similar varieties.

The new variety has been found to undergo asexual propagation in Spain by vegetative cuttings. Asexual propagation by vegetative cutting in Spain has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘I-15’.


The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety.

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2007 edition), London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on data collected from a four-year-old specimen during 2019 in Villafranca (Cordoba, Spain).
