Nectarine tree

Abstract

A nectarine tree which is medium size, medium vigorous, upright-spreadng, dense, and round-topped; foliated with medium size, ovate, lanceolate, acutely pointed, smooth, medium thick, medium green leaves having a crenate margin, a petiole of medium length and thickness, and medium size, irregularly alternate, green, reniform glands positioned on petiole and base of blade; blooms from buds medium in size and length, plump, appressed, and pubescent; the flowers, of medium season, being large and pink; and the tree is a regular and productive bearer of large, uniform, symmetrical, globose-slightly ovoid, freestone fruit having yellow skin blushed with red, yellow flesh streaked with red, and a brown 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 nectarine tree.

2. Classification of the Variety.

The present variety of nectarine tree is embraced by Class 41, Plants, of the U.S. Patent Office MANUAL OF CLASSIFICATION.

3. Prior Varieties.

Among existing varieties of nectarine trees which are known to me, and mentioned herein, is the Late Le Grand (U.S. Plant Pat. No. 1,035).

ORIGIN OF THE VARIETY

The present variety of nectarine tree was originated by me as an open-pollinated seedling of a late-ripening, unnamed, seedling nectarine tree. A number of such seedlings were grown to fruition, in the aforesaid experimental orchard, under careful and continuing observation by me; the present variety being a selection of one of such open-pollinated seedlings.

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 nectarine tree is, characteristically, of medium size, medium vigorous, upright-spreading, dense, and round-topped; foliated with medium size, ovate, lanceolate, acutely pointed, smooth, medium thick, medium green leaves having a crenate margin, a petiole of medium length and thickness, and medium size, irregularly alternate, green, reniform glands positioned on petiole and base of blade; blooms from buds medium in size and length, plump, appressed, and pubescent; the flowers, of medium season, being large and pink; and the tree is a regular and productive bearer of large, uniform, symmetrical, globose-slightly ovoid, freestone fruit having yellow skin blushed with red, yellow flesh streaked with red, and a brown stone.

The present variety of nectarine tree is further, and more particularly, characterized by late-ripening fruit -- as described -- which is freestone in comparison, for example, to the Late Le Grand and which -- along with many other late-ripening nectarines -- bears clingstone fruit; the fruit of the present variety ripening approximately with the Late Le Grand.

The present variety of nectarine tree is still further characterized by highly colored, late-ripening, freestone fruit of the best eating quality; the flavor being excellent, and slightly acid.

BRIEF DESCRIPTION OF THE DRAWING

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