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. Fruit with an attractive red skin color.
    • 2. Regular and heavy production of medium to large size fruit.
    • 3. Fruit with good flavor and eating quality.
    • 4. Firm fruit with good handling and shipping qualities.
    • 5. Vigorous, upright tree growth.

Description

Botanical classification: Prunus avium.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

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, ‘Bing’ Cherry (non-patented) and the proprietary selections ‘17H177’ and ‘49G1093’.

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. from an open pollinated seedling selection with the field identification number ‘17H177’. The seed parent (17H177) originated from an open pollinated proprietary seedling ‘49G1093’, which originated from a group of open pollinated seedlings of ‘Bing’ Cherry (non-patented). A large group of these open pollinated seedlings were budded on established ‘Mahaleb’ Rootstock (non-patented) to accelerate fruit production and maintained under close and careful observation. One such seedling, which is the present variety, exhibited desirable fruit and tree characteristics and was selected in 1986 for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

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 new and distinct variety of cherry tree is of large size, vigorous, upright growth and a regular and productive bearer of large size fruit with good flavor and eating quality. The fruit is further characterized by its attractive red skin color and firm flesh. In comparison to its immediate seed parent (17H177) the fruit of the new variety is larger in size, firmer and ripens approximately 6 days later. In comparison to its ancestor ‘Bing’ Cherry (non-patented) the fruit matures in the same season with larger size, is less susceptible to rain cracking, fruit doubling and spurs.

PHOTOGRAPH OF THE VARIETY

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 20 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

DESCRIPTION OF THE VARIETY

The following is a detailed botanical description of the new variety of cherry tree, its flowers, foliage and fruit, as based on observations of 20 year old specimens grown near Modesto, Calif., with color in accordance with Munsell Book of color.

Any variety or selection observed during indexing of plant characteristics with abnormal fungus, bacterial, virus or insect susceptibility is destroyed and eliminated from our breeding program.

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.
