This application claims priority to Spanish Application No. 20205550, which was filed at Spanish Office of Vegetable Varieties in Spain on May 21, 2020, the contents of which are hereby incorporated by reference for all purposes. This application contains a new plant variety which shares the same parental cross as the plant variety described in co-pending U.S. application Ser. No. 17/326,951. The differences between these two varieties are discussed further below.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 and also has a weeping tree habit in contrast to the spreading tree habit of ‘Arbosana’. The new variety's size is smaller than the ‘Koroneiki’ variety and also has heavier fruit than the ‘Koroneiki’ variety. A non-parental variety that the new variety is most similar to is the ‘Arbequino’ variety (unpatented). The new variety's fat yield is similar to that of ‘Arbequino’ (produces 100 grams of fat yield per 1 Lbs of fruit) but differs from ‘Arbequino’ in that it possesses a very high and constant productivity (660 oil liter per acre and year). The new variety is different from the variety described in co-pending U.S. application Ser. No. 17/326,951 in that it has a slow alteration in the production between different years and smaller fruit which takes longer to ripen.
It was found that the new variety of the present invention possesses the following combination of characteristics:
- (a) the tree has a drooping 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 low weight and 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 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-20’.
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 accompanying photographs were taken from a specimen of the new variety that was 68 months old.
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 (Córdoba, Spain).
