Description

ORIGIN OF THE VARIETY

The present new variety of peach tree was originated by us in our experimental orchard located near Modesto, calif., as a first generation cross between a seedling selection with the field indentification number 39EB706 and Sweet Gem Peach (U.S. Plant Pat. No. 7,952). The female parent 39EB706 originated from a cross between two selected seedlings, 32EA300 and 11E284. The seedling selection 32EA300 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). The seedling selection 11E284 originated from seed of an open pollinated Red Grand Nectarine (U.S. Plant Pat. No. 1,060). A large group of these first generation seedlings were grown and maintained under close observation, during which time we recognized the desirable fruit characteristics of the present new variety and selected it for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

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

SUMMARY OF THE VARIETY

The present new variety of peach tree is of large size, vigorous upright growth and is a regular and productive bearer of large, firm, yellow flesh, clingstone fruit with an attractive red skin color. The fruit is further characterized by having good flavor and eating quality, holding firm on the tree 10 to 12 days after maturity (shipping ripe) and having good handling and storage quality. In comparison to its pollen parent Sweet Gem Peach (U.S. Plant Pat. No. 7,952) the fruit of the new variety is approximately one week earlier in maturity.

DESCRIPTION OF THE PHOTOGRAPH

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