Abstract

A peach tree which is of medium size and vigor, upright-spreading, dense, and round-topped; foliated with medium size, ovate, lanceolate and acutely pointed leaves having a crenate margin, small, green, irregularly opposite, globose glands, and a petiole medium in length and thickness; flowers from plump, appressed, pubescent flower buds of medium size and length; the flowers, of medium season, being large and pink; and the tree is a regular and productive bearer of uniform, medium size, symmetrical, globose, freestone fruit having yellow skin substantially overspread and flushed with medium light red, yellow flesh, and a medium size, elliptical, light buff stone.

Description

BACKGROUND OF THE VARIETY

1. Field of the Invention

In the conduct of an extensive plant breeding program--on behalf of a commercial farming company, and in such company's experimental orchard located near Fresno, Fresno County, Calif.--I have originated a substantial number of new and distinct varieties of fruit trees, and which include the present variety of peach tree.

2. Classification of the Variety

The present variety of peach tree is embraced by Class 43, Plants, of the U.S. Patent Office Manual of Classification.

3. Prior Varieties

Among existing varieties of peach trees which are known to me, and mentioned herein, are the Springcrest and Flavorcrest (both unpatented).

ORIGIN OF THE VARIETY

The present variety of peach tree was originated by me as a cross between the Flavorcrest (as the seed parent) and Springcrest (as the pollen parent). A number of seedlings of such cross were grown to fruition, in the aforesaid experimental orchard, under careful and continuing observation by me; the present variety being a selection from such seedlings which evidenced commercial promise.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the variety was successfully accomplished, under my direction and in the aforesaid experimental orchard, by budding; such asexual reproductions, in maturity, having run true to the original tree in all respects.

SUMMARY OF THE VARIETY

The present variety of peach tree is, characteristically, of medium size and vigor, upright-spreading, dense, and round-topped; foliated with medium size, ovate, lanceolate and acutely pointed leaves having a crenate margin, small, green, irregularly opposite, globose glands, and a petiole medium in length and thickness; flowers from plump, appressed, pubescent flower buds of medium size and length; the flowers, of medium season, being large and pink; and the tree is a regular and productive bearer of uniform, medium size, symmetrical, globose, freestone fruit having yellow skin substantially overspread and flushed with medium light red, yellow flesh, and a medium size, elliptical, light buff stone.

The present variety of peach tree is further characterized, in comparison with the Springcrest (the pollen parent), by fruit which bears general resemblance in size, shape, and appearance, but ripens about a week later.

The present variety of peach tree is further characterized, in comparison with Flavorcrest (the seed parent), by fruit which is smaller in size, smoother and more rounded in shape, with less pubescence, and ripens about three weeks earlier.

By reason of the ripening period of its fruit relative to that of the Springcrest and Flavorcrest, the present variety of peach tree is in harvest and desirably provides Sprincrest-type fruit to the market in the harvest-period gap between said other varieties; the fruit of the present variety being additionally characterized by red external or skin color which does not become too dark under California growing conditions.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is an illustration, by photographic reproduction in color, of a twig with leaves, separate fruit, and a separate stone; one such fruit being half cut away to expose the flesh and stone; the latter remaining in place.
