1. A heavy and regular bearer of fruit.

2. Fruit with excellent flavor and eating quality.

3. Bearing large, firm, white flesh, freestone fruit.

4. Fruit with a high degree of attractive orange-red skin color.

5. Fruit with good handling and shiping quality.

6. Vigorous, upright growth.

Description

ORIGIN OF THE VARIETY

The present new and distinct variety of peach tree was originated by us in our experimental orchard located near Modesto, Calif., as a first generation cross between two selected seedlings with field identification numbers 107ED101 and 97GF518. Both the seed parent (107ED101) and the pollen parent (97GF518) originated as open pollinated Snow Giant Peach (U.S. Plant Pat. No. 8,085) seedlings. A large group of these first generation seedlings were grown under careful observation, during which time the present variety exhibited the desirable fruit characteristics described above and was selected for asexual propagation and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The present variety of peach tree was asexually reproduced by budding, as performed by us in our experimental orchard located near Modesto, Calif., and shows that all characteristics come true to form and are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE VARIETY

The herein described new and distinct 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 further characterized by being relatively uniform in size throughout the tree; having firm flesh with good handling and shipping quality; having a high degree of attractive orange-red skin color and ripening in the late maturity season, approximately 6 to 7 days after Snow Giant peach (U.S. Plant Pat. No. 8,085).

DESCRIPTION OF THE PHOTOGRAPH

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