- TODOLIVO, S.L.

A new and distinct variety of olive tree, herein referred to by its cultivar name, ‘I-50’, is provided which forms a spreading growth habit. Fruit with a low weight and obtuse shape is produced. The fruit exhibit black coloration and the fruit nipple is either absent or weakly present. The stone of the fruit of the new variety is of very low to low weight, very elongated and possess a weakly rugose surface.

Description

Botanical/commercial classification: Latin name: Olea europaea L. Common name: Olive tree.

Varietal Denomination: ‘I-50’.

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 less intense green when compared to the color of the ‘Arbosana’ variety. The new variety has a higher yield fat than ‘Arbosana’. The new variety's size is smaller than the ‘Koroneiki’ variety and similar to ‘Arbosana’. Table 1 further lists some of the differences and similarities between the new variety and its parentage.

TABLE 1 Differences and similarities between new variety and its parentage DIFFERENCES I-50 ARBOSANA KORONEIKI TREE TYPE Normal Semi-Dwarf Normal TREE HABIT Spreading Spreading Spreading FRUIT WEIGHT About 1.6 g About 1.43 g About 1.07 g STONE WEIGHT About 0.2 g About 0.23 g About 0.19 g

The new variety is different from the related ‘I-15’ variety (patented as U.S. Plant Pat. No. 32,302 P3) since it has an earlier bearing than ‘I-15’. The new variety is also different from the ‘I-30’ variety (U.S. Ser. No. 17/376,725) since it has at least 3 points more oil yield (percentage of olive oil in fruit). Table 2 further lists some of the differences and similarities between the new variety and related cultivars, such as the ‘I-42’ variety (U.S. Ser. No. 17/376,586).

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

    • (a) the tree has a spreading growth habit
    • (b) the fruit weight is low and the fruit color is black
    • (c) the fruit is obtuse and weakly asymmetric
    • (d) the fruit possesses either an absent or weak nipple
    • (e) the stone is very elongated with a very low to low weight and possesses a weakly 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. The new variety has a small variety size.

The new variety has been found to undergo asexual propagation in Villafranca de Córdoba, Córdoba, 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-50’.
