Heavy and regular production of fruit.3. Fruit with firm flesh, good handling and shipping quality.4. Fruit with a high degree of attractive red skin color.5. Vigorous upright growth.6. Coloring of fruit 6 to 8 days before maturity.

Description

ORIGIN OF THE VARIETY

The new variety of peach tree was originated by us in our experimental orchard located near Modesto, Calif., as a first generation cross between two selected seedlings with field identification numbers 47EB362 and 57RA292. The maternal parent, with field identification number 47EB362, originated from a cross between a selected seedling from open pollinated O'Henry Peach (U.S. Plant Pat. No. 2,964) seed and a selected seedling from the cross of Sam Houston Peach (non-patent) with May Grand Nectarine (U.S. Plant Pat. No. (2,794). The paternal parent, with field identification number 57RA292, originated from a cross between Amparo Peach (U.S. Plant Pat. No. 6,472) and a seedling selection which originated from a cross between a peach of unknown parentage and June Lady Peach (U.S. Plant Pat. No. 3,022). A large group of these first generation seedlings were grown and maintained by us and gave many and varying characteristics. One such seedling, which is the present variety, being especially desirable with respect to its fruit, 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 by us in our experimental orchard located near Modesto, Calif., which shows that all characteristics of the tree and its fruit are established and transmitted through succeeding propagations and come true to the original tree in all respects.

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree is of large size, has vigorous upright growth and is a productive and regular bearer of large, yellow flesh, semi-freestone fruit with good flavor and eating quality. The fruit is further characterized by having firm flesh, good handling and shipping quality, an attractive red skin color and in comparison to Amparo Peach (U.S. Plant Pat. No. 6,472) which it closely resembles, the new variety is approximately 1 week later in maturity.

PHOTOGRAPH OF THE NEW VARIETY

The accompanying photographic illustration shows typical specimens of the foliage and fruit of the new variety of peach tree. The photographic illustration depicts the upper and lower surface of the leaves, an exterior and sectional view of the fruit, with a fruit divided in the suture plane to reveal flesh coloration, pit cavity and a stone remaining in place. The photographic illustration 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.
