Description

ORIGIN OF THE VARIETY

Our new variety of peach tree was originated by us in the experimental orchard located at Modesto, Calif. as a second generation seedling 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). A selection having desirable characteristics, including firm white flesh, was made from the first generation and this selection was selfed to produce a large number of seedlings which were grown and maintained under close observation and the present variety which evidenced distinctive desirable characteristics was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The present new variety of peach tree was asexually reproduced by budding, as performed at our experimental orchard located at Modesto, Calif., shows that the said characteristics described above come true to form and are established and transmitted through succeeding propagations.

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree is of large size, vigorous, upright growth and a regular and productive bearer of large, firm, white flesh, freestone fruit with an attractive red skin color, good flavor and eating quality and the ability to ship to long distance markets; the fruit is further characterized in comparison to Giant Babcock Peach (U.S. Plant Pat. No. 1,353) by maturing 5 to 6 days later, 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 photographic illustrations show typical specimens of the fruit and foliage of the new variety, an exterior and sectional view of the fruit being shown with a stone remaining in place and the upper and lower surface of the leaves being illustrated. These 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.
