USPP10790P - Cherry tree named `Royal Rainier` - Google Patents

Abstract

A new and distinct variety of cherry tree (Prunus avium) with the following unique combination of desirable features that are outstanding in a new variety:

1. Fruit with good flavor and eating quality.

2. Firm fruit with good handling and shipping qualitites.

3. Heavy and regular production of medium to large size fruit.

4. The ability of the fruit to hold firm on the tree 6 to 7 days after maturity (shipping ripe).

5. Vigorous, upright growth.

6. Fruit with yellowish-white skin that has an attractive red blush when exposed to the sun.

Description

ORIGIN OF THE VARIETY

The new and distinct variety of cherry tree named `Royal Rainier` was originated as an open pollinated seedling of 32G153. The selection 32G153 originated as an open pollinated seedling of Stella Cherry (non-patented). A large number of these open pollinated seedlings were grown under careful observation by us in our experimental orchard located near Modesto, Calif. One such seedling, which is the present variety, being especially desirable for its fruit quality and heavy production, was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the new and distinct variety of cherry tree was by budding, as performed by us in our experimental orchard located near Modesto, Calif., and shows that all characteristics of the tree and its fruit run true to the original tree and are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE VARIETY

The new and distinct variety of cherry tree is of large size, vigorous, upright growth and a regular and productive bearer of medium to large size fruit with good flavor and eating quality. The fruit is further characterized by its yellowish-white skin having an attractive red blush when exposed to the sun, firm flesh, the ability to hold firm on the tree 6 to 7 days after maturity (shipping ripe) and ripening approximately 5 days before the Stella Cherry (non-patented).

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 fruit divided in it 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) and the colors are as nearly true as is reasonably possible in a color representation of this type.
