Abstract

A new and distinct variety of nectarine tree. The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:
    • 1. Heavy and regular bearer of large size fruit.
    • 2. Producing fruit that has a mild, sweet, sub-acid flavor with very good eating quality.
    • 3. Producing fruit with good handling and shipping quality.
    • 4. Fruit holding firm on the tree 8 to 10 days past maturity.
    • 5. Vigorous and upright tree growth.

Description

Botanical classification: Prunus persica var. nucipersica.
BACKGROUND OF THE VARIETY Field of the Invention
In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricots, cherries, almonds and interspecifics are exemplary. It was against this background of our activities that the present variety of nectarine tree was originated and asexually reproduced by us in our experimental orchard located near Modesto, Stanislaus County, Calif.
PRIOR VARIETIES
Among the existing varieties of nectarine trees, which are known to us, and mentioned herein are, ‘Honey Royale’ (U.S. Plant Pat. No. 12,008), ‘Ruby Gold’ (U.S. Plant Pat. No. 3,101) and two proprietary seedling selections ‘349LH508’ and ‘6W60’.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct nectarine tree (Prunus persica var. nucipersica) was originated by us in our experimental orchard from seed of a first generation cross between a selected proprietary seedling with the field identification number ‘349LH508’ and ‘Honey Royale’ Nectarine (U.S. Plant Pat. No. 12,008). The seed parent (349LH508) originated from a cross of a proprietary nectarine seedling (6W60) of unknown parentage and ‘Ruby Gold’ Nectarine (U.S. Plant Pat. No. 3,101). We planted and maintained under close and careful observation, a large group of these first generation seedlings on their own root system. One seedling, which is the present variety, exhibited desirable fruit characteristics and was selected in 2002 for additional asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE NEW VARIETY
Asexual reproduction of the new and distinct variety of nectarine tree was by budding to ‘Nemaguard’ Rootstock (non-patented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that reproductions run true to the original tree and all characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagations.
SUMMARY OF THE NEW VARIETY
The new variety of nectarine tree (Prunus persica var. nucipersica) is of large size, vigorous upright growth and a regular and productive bearer of large, firm, yellow flesh, clingstone fruit with good handling and shipping quality. The fruit is further characterized by having moderateIy juicy flesh with a mild, sweet, low acid flavor that has very good eating quality. In comparison to its seed parent (349LH508) the fruit of the new variety is larger in size and ripens approximately 12 days later. In comparison to its pollen parent ‘Honey Royale’ (U.S. Plant Pat. No. 12,008) the fruit of the new variety ripens approximately 24 days later.
PHOTOGRAPH OF THE VARIETY
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new nectarine variety. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a single fruit divided in its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) from a 7 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
