Abstract

A new and distinct variety of cherry tree. The following features of the tree and its fruit are characterized with the tree budded on ‘Mahaleb’ 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. Tree having a vigorous, upright growth habit.
    • 2. Regular and productive bearer of medium to large size fruit.
    • 3. Fruit with an attractive red skin color.
    • 4. Fruit with good flavor and eating quality with a good balance between acid and sugar.
    • 5. Fruit with firm flesh that has good handling and shipping qualities.

Description

Botanical designation: Prunus avium.
Variety denomination: ‘Royal Fran’.
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 cherry 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 cherry trees, which are known to us, and mentioned herein, ‘Royal Elaine’ Cherry (U.S. Plant Pat. No. 22,603), ‘Minnie Royal’ Cherry (U.S. Plant Pat. No. 12,942), ‘Royal Hazel’ Cherry (U.S. Plant Pat. No. 19,920) and the proprietary non-patented cherry seedling selection ‘24Z399’.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The present new variety of cherry tree (Prunus avium) was originated by us in our experimental orchard located near Modesto, Calif., as an open pollinated seedling from the proprietary non-patented cherry seedling ‘24Z399’, which originated as a first generation cross between ‘Royal Elaine’ Cherry (U.S. Plant Pat. No. 22,603) and ‘Minnie Royal’ Cherry (U.S. Plant Pat. No. 12,942). A large group of these open pollinated seedlings were budded and maintained on established ‘Mahaleb’ Rootstock (non-patented) to accelerate fruit production for evaluation. Under close and careful observation the present seedling exhibited desirable fruit and tree characteristics and was selected in 2003 for additional asexual reproduction and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
In 2003, asexual reproduction of the new and distinct variety of cherry tree was by budding to ‘Mahaleb’ 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 present new variety of cherry tree (Prunus avium) is of large size, vigorous, upright growth and a regular and productive bearer of large size fruit with an attractive dark red skin color. The fruit is further characterized by having good flavor and eating quality with good handling and shipping qualities. In comparison to its proprietary non-patented cherry seed parent ‘24Z399’ the fruit of the new variety is approximately 10 days earlier in maturity. In comparison to the commercial variety ‘Royal Hazel’ Cherry (U.S. Plant Pat. No. 19,920) the fruit of the new variety is approximately 5 days later in maturity.
DESCRIPTION OF THE PHOTOGRAPH
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new cherry 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 14 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

Any variety observed during indexing of plant characteristics with abnormal fungus, bacterial, virus or insect susceptibility is destroyed and eliminated from our breeding program. No atypical resistances/susceptibilities have been noted under normal cultural practices. The present new variety of cherry tree, its flowers foliage and fruit herein described may vary in slight detail due to climate, soil conditions and cultural practices under which the variety may be grown. The present description is that of the variety grown under the ecological conditions prevailing near Modesto, Calif.
