Peach tree ("Double Jewel")

Abstract

A new and distinct variety of peach tree which is of large size, vigorous upright growth and bearing large size, attractive, double pink flowers in the spring, giving the appearance of a flowering type ornamental tree but being a productive and regular bearer of large size, yellow flesh, freestone fruit with good eating quality; the fruit is further characterized by having firm flesh, a yellow ground color which is overspread with an attractive red skin color.

Description

ORIGIN OF THE VARIETY

The present variety of peach tree was developed in the experimental orchard located at Modesto, Calif., from a cross between a selected nectarine seedling, which originated from an open pollinated Red Grand Nectarine (U.S. Plant Pat. No. 1,060) and a genetic dwarf peach of unknown parentage which produced attractive double pink flowers and large yellow flesh peaches. We grew and maintained these seedlings under close observation and we recognized its desirable dual purpose flowering and fruiting characteristics described above and selected the variety for reproduction.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual propagation of the new and distinct variety of peach tree by budding was performed in the experimental orchard at Modesto, Calif. and shows that said characteristics come true to form and are established and transmitted through succeeding propagations.

SUMMARY OF THE VARIETY

The present variety relates to a new and distinct variety of peach tree which is of large size, upright growth and bearing large, attractive, double pink flowers in the spring and is a regular and productive bearer of large, yellow flesh, freestone fruit ripening in late June at Modesto, Calif. The new variety is further characterized by having a high degree of attractive red skin color, uniform ripening and firm flesh with good eating quality.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the foliage and fruit of the new variety, with the upper and lower surface of the leaves being illustrated and fruit specimens showing the exterior and a sectional view being depicted with a stone remaining in place. The illustrations were taken shortly after being picked at maturity (firm ripe) and the colors are as nearly true as reasonably possible in a color representation of this type.

Kornerup and J. H. Wanscher.
