Abstract

A new variety of nectarine tree discovered as a seedling of an open pollenated Red Grand nectarine tree growing in Fresno County, located in the San Joaquin Valley of California. The fruit of the new variety tends to ripen later than the Red Grand variety and is characterized by a strong red color over a moderate orange, the strong red coloring spreads from a substantially solid covering near the base of the fruit to blotches of strong red coloring near the apex.

Description

BACKGROUND OF THE VARIETY

The newly discovered variety of nectarine tree is characterized by yellow-fleshed, clingstone fruit, and a tree similar in many respects to the Red Grand variety of nectarine tree, the subject of U.S. Plant Pat. No. 1,060, which ripens earlier than the new discovered variety.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

Seeds selected from open pollenated Red Grand variety nectarine trees were planted in a plot at the southwest corner of Summer and Buttonwillow Avenues near Reedley, Calif., located in the San Joaquin Valley. A seedling was selected and bud wood was taken therefrom. Several trees growing in a test plot for a commercial orchard located near Monson, in Fresno County, Calif., were grafted-over using bud wood taken from the selected seedling and the grafted-over trees have been carefully watched. Comparisons of fruit taken from the grafted-over trees and the seedling confirm that the new variety of nectarine tree is distinct by virtue of coloring of the fruit and dates of ripening, which dates tend to be later than that of the patented Red Grand variety.

SUMMARY OF THE VARIETY

The fruit of the new variety is generally uniform and colors during the later part of the first week in August and becomes fully ripe between the third and fourth weeks of August, when grown under conditions normally found in the San Joaquin Valley of California. The fruit of the new variety tends to ripen later than the Red Grand variety and is characterized by a strong red color over a moderate orange, the strong red coloring spreads from a substantially solid covering near the base of the fruit to blotches of strong red coloring near the apex. The fruit has a long harvest period and keeps well on the trees.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing illustrates typical specimens of the fruit and foliage of the new variety. Two specimens being shown in cross-section, with the seeds thereof being separately shown, and four other specimens being shown from different perspectives for illustrating size, form and coloring; the foliage is shown to illustrate typical leaf size and form.

DETAILED DESCRIPTION

The following is a detailed description of my new variety with color terminology being in accordance with the Nickerson Color Fan, obtainable from Munsell Color Company, Baltimore 2, Md., except in instances where terminology having generally accepted meaning is employed.

Parentage: Seedling grown from a seed of an open pollenated Red Grand variety of nectarine tree, U.S. Plant Pat. No. 1,060.

Propagation: Maintains its distinguishing characteristics through asexual reproduction.

Locality where grown and observed:

Near.--Reedley, County of Fresno, Calif.

Although the new variety of nectarine tree possesses the described characteristics as a result of the growing conditions in Fresno County, Calif., in the central portion of the San Joaquin Valley, it is to be understood that variations of the usual magnitude in characteristics incident to growing conditions, fertilization, pruning and pest control are to be expected.

Claims

Having thus described and illustrated my new variety of nectarine tree, what is new and desired to be secured by Letters Patent is:

1. A new and distinct variety of Nectarine tree, substantially as illustrated and described, which is similar in size, productivity and regularity of bearing to the Red Grand variety of nectarine tree from which the new variety was derived as a seedling, the seedling was grown from an open-pollenated seed taken from a tree of the Red Grand variety growing near an orchard containing trees of the late LeGrand variety of nectarine tree; the new variety bears generally uniform, clingstone fruit characterized by yellow flesh and smooth skin having a strong red coloring over a moderate orange coloring, the strong red coloring spreading from a substantially solid covering near the base of the fruit to blotches of a strong red coloring near the apex of the fruit, and the fruit ripens in the San Joaquin Valley of California about four weeks later than the fruit of the Red Grand variety.
