Description

ORIGIN OF THE VARIETY

The present new and distinct variety of peach tree was originated by us in the experimental orchard, located at Modesto, Calif. as a first generation seedling of a cross between two seedling selections. The maternal seedling parent was a selection from a group of open-pollinated O'Henry Peach (U.S. Plant Pat. No. 2,964) seedlings and the pollen-parent originated from a cross between two seedling selections; one seedling (the maternal parent) originated from a group of open-pollinated May Grand Nectarine (U.S. Plant Pat. No. 2,794) seedlings and the pollen-parent originated from seedlings of open-pollinated Sam Houston Peach (Non-patented).

ASEXUAL REPRODUCTION OF THE VARIETY

Our new and distinct variety of peach tree was asexually reproduced by budding in the experimental orchard located at Modesto, Calif., and the reproductions show that said characteristics of the tree and its fruit are established and transmitted through succeeding reproductions and come true to the original tree in all respects.

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree which is of large size, medium dense, upright in growth and a regular and productive bearer of large, very firm, yellow flesh, freestone fruit with good flavor and eating quality. The present variety of peach tree is further characterized as to its novelty by producing fruit that will hold firm on the tree 7-10 days after shipping ripe, being nearly uniform in size throughout the tree, having very good storage and shipping quality and having a high degree of attractive red skin color.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the foliage and fruit of the present new variety of peach tree, with the exterior and cross sectional view of the fruit divided in its suture plane to reveal flesh coloration, pit cavity and showing a stone remaining in place. The photographs were taken shortly after being picked at maturity (shipping ripe) and the colors are as nearly true as is reasonable possible in a color representation of this type.
