The present new and distinct variety of nectarine tree has the following unique combination of desirable features that are outstanding in a new variety:1. Fruit with an attractive red skin color.2. Late maturity of freestone fruit.3. Fruit with good flavor and eating quality.4. Fruit with firm flesh, good storage and shipping quality.5. Heavy and regular bearing of fruit.6. Relatively uniform size fruit throughout the tree.

Description

ORIGIN OF THE VARIETY

The present variety of nectarine tree was originated by us in our experimental orchard located near Modesto, Calif., from a second generation seedling of a cross between two selected seedlings with the field identification numbers 60G329 and 20G902. The maternal parent 60G329 originated from a second generation seedling of a cross between Sun Grand Nectarine (U.S. Plant Pat. No. 974) and Merrill Gem Peach (U.S. Plant Pat. No. 868). The pollen parent 20G902 originated from a cross between a nectarine of unknown parentage and Autumn Grand nectarine (U.S. Plant Pat. No. 2,894). A large group of these second generation seedlings were planted and grown under careful and continual observation by us, during which time we recognized the desirable fruit characteristics described above and selected the present variety for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the new and distinct variety of nectarine tree by budding was 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 form and are established and transmitted in succeeding propagations.

SUMMARY OF THE VARIETY

The new and distinct variety of nectarine tree is of large size, vigorous, upright in growth and is productive and regular bearer of large, yellow flesh freestone fruit with good flavor and eating quality. The fruit is further characterized by having firm flesh with good storage and shipping ability, being relatively uniform in size throughout the tree and in comparison to the clingstone Nectarine August Glo (U.S. Plant Pat. No. 8,039) which ripens in the same maturity season, the fruit of the new variety is freestone.

PHOTOGRAPH OF THE NEW VARIETY

The accompanying photograph shows a reproduction in color of typical specimens of the foliage and fruit of the present variety. It depicts the upper and lower surface of the leaves, an exterior and sectional view of the fruit, with a fruit being divided on its suture plane to reveal flesh coloration and to show a stone remaining in place. The photographic illustration was taken shortly after the fruit was picked (firm ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.

Claims

1. A new and distinct variety of nectarine tree, substantially as illustrated and described, which is of large size, vigorous, upright in growth and a productive and regular bearer of large, firm, yellow flesh, freestone fruit with good flavor and eating quality; the fruit is further characterized by being nearly uniform in size throughout the tree, having good storage and shipping quality and, in comparison to August Glo Nectarine (U.S. Plant Pat. No. 8,039), the new variety matures in the same maturity season but is freestone instead of clingstone.
