Peach tree "Snow King"

Abstract

A new and distinct variety of peach tree, its novelty consists of the following unique combination of features that are outstanding in a new variety.1. Heavy and regular bearer of fruit.2. Having large, firm, white flesh, freestone fruit.3. Fruit with excellent flavor and eating quality.4. The ability of the fruit to stay firm on the tree 6-7 days after maturity (shipping ripe).5. Fruit with a high degree of attractive red skin color.6. Vigorous upright growth.

Description

ORIGIN OF THE VARIETY

The present new variety of peach tree was developed by us in our experimental orchard located near Modesto, Calif. as a first generation cross between two selections with the field identification numbers 33R320 and 29G672. The female parent 33R320 originated from a cross between a nectarine of unknown parentage and Redwing Peach (U.S. Plant Pat. No. 621). The pollen parent 29G672 originated from seed of an open pollinated O'Henry Peach (U.S. Plant Pat. No. 2,964). We grew and maintained a large group of these first generation seedlings under careful observation, during which time the present variety exhibited the distinctive desirable fruit characteristics described above and was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The new and distinct variety of peach tree was asexually propagated by budding, as performed by us in our experimental orchard located near Modesto, Calif. and shows that all characteristics are established and transmitted through succeeding propagations and come true to the original tree in all respects.

SUMMARY OF THE VARIETY

The herein described variety of peach tree is of large size, vigorous upright growth and a productive and regular bearer of large, firm, white flesh, freestone fruit with excellent flavor and eating quality. The fruit is relatively uniform in ripening throughout the tree, holds firm on the tree 6 to 7 days after maturity (shipping ripe), has good handling and shipping quality and ripens in the late maturity season, approximately 5 to 6 days after O'Henry Peach (U.S. Plant Pat. No. 2,964).

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic illustrations show typical specimens of the foliage and fruit of the present new variety of peach tree, with the upper and lower surface of the leaves being illustrated, an exterior and sectional view of the fruit being divided in the suture plane to reveal flesh coloration, pit cavity and a stone remaining in place. The photographic illustrations were taken shortly after being picked at maturity (shipping ripe) and the colors are as nearly true as reasonably possible in a color representation of this type.

DESCRIPTION OF THE VARIETY

The botanical details of this new and distinct variety of peach tree, its flowers, foliage and fruit are based on observations of specimens grown in our experimental orchard, located near Modesto, Calif. with color terminology (except those in common terms) in accordance with Reinhold Color Atlas by A. Kornerup and J. H. Wanscher.
