Olive tree named ‘I-16’

Abstract

A new and distinct variety of olive tree, herein referred to by its cultivar name, ‘1-16’, is provided which forms an upright to spreading growth habit. Fruit with a low weight and obtuse shape is produced. The fruit exhibit dark violet coloration and the fruit nipple is absent or weak. The stone of the fruit of the new variety is of medium weight, moderately elongated and possesses a moderately rugose surface.

Description

Botanical/commercial classification:

Latin name—Olea europaea L.

Common name—Olive tree.

Varietal denomination: ‘I-16’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Spanish Application No. 20205555, which was filed at Spanish Office of Vegetable Varieties in Spain on Jul. 16, 2020, the contents of which are hereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

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:
‘ARBOSANA’ x ‘KORONEIKI’.

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's color is a more intense green when compared to the color of the ‘Arbosana’ variety. The new variety's size is smaller than the ‘Koroneiki’ variety. The new variety is different from the ‘I-15’ variety disclosed in U.S. Plant Pat. No. 32,302 in that it has a longer leaf, higher internode number and a higher canopy density.

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

• • (a) the tree has a upright to spreading growth habit
  • (b) the fruit weight is low and the fruit color is dark violet
  • (c) the fruit is obtuse and weakly asymmetric
  • (d) the fruit either possesses a weak or absent nipple
  • (e) the stone is moderately elongated with a medium weight and moderately rugose surface.

The new variety well meets the needs of the horticultural industry and has not been commercialized. The new variety has an easy agronomic management.

The new variety can be readily distinguished from related similar varieties. For example, the new variety is a small olive cultivar adapted to be cultivated in super high density olive orchards to fulfill the demands of the olive oil sector. In this way, the new variety has a different exact time to ripening, in this case late, different organoleptic characteristics and a different vigor when compared to related varieties since the new variety is specifically cultivated to meet the standards of the olive oil sector. The new variety has a small variety size.

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-16’.
