Description

ORIGIN OF THE VARIETY

The herein new variety of peach tree was originated by us in our experimental orchard located near Modesto, Calif. as a second generation seedling from a cross between two selections. The female parent was a selection from a cross beween O'Henry Peach (U.S. Plant Pat. No. 2,964) and Giant Babcock Peach (U.S. Plant Pat. No. 1,353) and the male parent originated from a cross of May Grand Nectarine (U.S. Plant Pat. No. 2,794) and Sam Houston Peach (Non-patented). We grew and maintained a large number of these second generation seedlings under close observation, one such seedling which is the present variety, having especially desirable fruit characteristics was selected for reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The present new and distinct 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 propagations.

SUMMARY OF THE VARIETY

The present variety of peach tree is of large size, vigorous, upright in growth and a regular and productive bearer of large, very firm, white flesh, freestone fruit with excellent flavor and eating quality. The fruit is further characterized by coloring 6 to 7 days before maturity, having an attractive red skin color and the ability to ship to long distance markets. The present variety of peach tree is further characterized in comparison to Giant Babcock Peach (U.S. Plant Pat. No. 1,353) by maturing fruit approximately 34 days earlier, having firmer white flesh with greater shipping and storage ability and a higher degree of attractive red skin color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show reproductions in color of typical specimens of foliage and fruit of the new variety of peach tree, with the upper and lower surface the foliage being illustrated, an exterior and a sectional view of the fruit being shown with a stone remaining in place. The photographs were 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.
