Abstract

A new and distinct variety of nectarine tree which has the following unique combination of features that are desirable in a new variety:1. Heavy and regular production of fruit.2. Fruit with excellent flavor and eating quality.3. Fruit with firm white flesh having good handling, storage and shipping quality.4. Fruit having a high degree of soluble solids, (14.8 Brix).5. Fruit ripening in the late maturity season.6. Relatively uniform maturity of large, freestone fruit.7. Having a vigorous, upright growth habit.

Description

ORIGIN OF THE VARIETY

Our new and distinct nectarine variety was originated by us in our experimental orchard located near Modesto, Calif. as a third generation seedling from a cross between two selected seedlings with the field identification numbers of 21GA1110 and 32EA260. The seedling 21GA1110, which is the female parent originated from a cross between Ruby Gold Nectarine (U.S. Plant Pat. No. 3,101) and Redwing Peach (U.S. Plant Pat. No. 621) and the pollen parent with the identification number of 32EA260 originated from a cross between O'Henry Peach (U.S. Plant Pat. No. 2,964) and Giant Babcock Peach (U.S. Plant Pat. No. 1,353). A large group of these third generation seedlings were grown and maintained under close observation, one such late maturing seedling, which is the present variety, having especially desirable fruit characteristics was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

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

SUMMARY OF THE VARIETY

The present new and distinct variety of nectarine tree is of large, vigorous, upright growth and a regular and productive bearer of large, firm, white flesh, freestone fruit with excellent flavor and eating quality. The fruit is further characterized by being relatively uniform in maturity, having good handling and shipping quality, a high degree of attractive red skin color and ripening in the late maturity season.

DESCRIPTION OF THE PHOTOGRAPHS

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