Claims:
We claim:

1. A new and distinct variety of peach tree, substantially as illustrated and described, characterized by its large size, vigorous, upright growth, and being a productive and regular bearer of large, firm, yellow flesh, freestone fruit with a sweet, mild, sub-acid flavor with excellent eating quality; the fruit is further characterized by being relatively uniform throughout the tree, having good handling and shipping quality; and maturing in the late season, approximately 5 weeks after O'Henry Peach (U.S. Plant Pat. No. 2,964).

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, identification numbers 108ED304 and 103ED581. The maternal parent (108ED304), originated from a cross of a selected seedling with White Lady Peach (U.S. Plant Pat. No. 5,821). The selected seedling originated from a cross of Red Grand Nectarine (U.S. Plant Pat. No. 1,060) with Redwing Peach (U.S. Plant Pat. No. 621). The paternal parent (103ED581), originated from a seedling selected from an open pollinated O'Henry Peach (U.S. Plant Pat. No. 2,964) crossed with a high-colored peach seedling of unknow parentage. A large group of these first generation seedlings were planted and maintained under close observation and the present variety exhibited the late maturing fruit characteristics described above and was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The present new peach variety was asexually reproduced by budding, as performed by us in our experimental orchard located near Modesto, Calif., which shows that all characteristics run true to the original tree in all respects and are established and transmitted in succeeding asexual propagations.

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree is of large size; vigorous, upright growth; and a productive and regular bearer of large, firm, yellow flesh, freestone fruit with a mild, sweet, sub-acid flavor and excellent eating quality. The fruit is further characterized by being relatively uniform throughout the tree, having good handling and shipping quality, holding firm on the tree for 10 to 12 days after maturity (shipping ripe); and in comparison to the O'Henry Peach (U.S. Plant Pat. No. 2,964), the fruit of the new variety is approximately 5 weeks later in maturity.

DESCRIPTION OF THE PHOTOGRAPH

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