A new and distinct variety of peach Prunus persica tree which has the following unique combination of features that are desirable in a new variety:1. Heavy and regular bearer of large size fruit.2. Producing mild, sub-acid fruit with very good flavor and eating quality.3. Fruit with firm white flesh, good handling and shipping quality.4. Fruit with a high degree of attractive red skin color.5.

Description

ORIGIN OF THE VARIETY

The present new variety of peach tree was developed by us in our experimental orchard located near Modesto, Calif., as a second generation cross between two selected seedlings, field identification numbers 24GA795 and 24R215. The maternal parent, field identification number 24GA795 , originated from a cross between Red Grand Nectarine (U.S. Plant Pat. No. 1,060) and Redwing Peach (U.S. Plant Pat. No. 621). The paternal parent, field identification number 24R215, originated as a seedling selection developed from the cross of O'Henry Peach (U.S. Plant Pat. No. 2,964) and Giant Babcock Peach (U.S. Plant Pat. No. 1,353), crossed with Top Crest Peach (U.S. Plant Pat. No. 5,745). We grew and maintained a large group of these second generation seedlings under careful observation, during which time we recognized its desirable fruit characteristics and selected the present variety for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The new and distinct variety of peach tree was asexually propagated by budding, as performed by us in our experimental orchard located near Modesto, Calif., and shows that such reproductions run true to the original tree and all said characteristics are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE VARIETY

The present 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, clingstone fruit with very good flavor and eating quality. The fruit is further characterized by being relatively uniform in ripening throughout the tree; having a high degree of attractive red skin color; having good handling and storage quality; ripening in the early maturing season; and in comparison to the early maturing, yellow flesh Top Crest Peach (U.S. Plant Pat. No. 5,745) fruit, the new variety has white flesh, greater production of larger size fruit, more attractive red skin color and is approximately 26 days later in maturity.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photographic illustration shows typical specimen of the fruit and foliage of our new peach variety. Illustrated are the upper and lower surface of the leaves, a specimen showing the exterior and sectional view of a fruit divided in its suture plane to reveal flesh coloration, pit cavity and a stone remaining in place. The photograph was 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.
