Nectarine tree (48-G-140)

Abstract

A nectarine tree which is medium size, vigorous, upright to spreading, open, foliated with medium size, lanceolate, acutely pointed leaves having a crenate margin and alternate, reniform glands, blooms mid-season with large flowers, and is a regular and productive bearer of large to medium size, symmetrical, globose, freestone fruit having yellow skin substantially overspread with red, and yellow flesh with red next to the stone.

Description

BACKGROUND OF THE VARIETY

1. Field of the Invention

Over a substantial number of years I have engaged in an extensive and continuing plant breeding program at my experimental nursery and orchard located near Le Grand, Merced County, California; one purpose of such program being to provide improved varieties of fruit trees. The present variety of nectarine tree resulted from my endeavors in the conduct of such plant breeding program; such variety being embraced by Class 41, Plants, of the United States Patent Office MANUAL OF CLASSIFICATION.

2. Prior Varieties

Among the existent varieties of nectarine trees which are known to me, I make particular reference to the Le Grand (U.S. Plant Pat. No. 549) mentioned hereinafter for the purpose of comparison.

ORIGIN OF THE VARIETY

The present variety of nectarine tree was originated by me, in my experimental nursery and orchard, located as aforesaid, as a cross between the Summer Grand (U.S. Plant Pat. No. 2,879) as the seed parent and May Grand (U.S. Plant Pat. 2,794) as the pollen parent. In maturity, such cross evidenced certain desirable characteristics for commercial production, and I, therefore, selected it for asexual reproduction.

ASEXUAL REPRODUCTION OF THE VARIETY

Subsequent to origination and selection by me of the present variety of nectarine tree, I asexually reproduced it by top-working on mature trees in my said experimental orchard, and--in maturity--such reproductions ran true to the original tree in all respects.

SUMMARY OF THE VARIETY

The herein-claimed new and distinct variety of nectarine tree is medium size, vigorous, upright to spreading, open, foliated with medium size, lanceolate, acutely pointed leaves having a crenate margin and alternate, reniform glands, blooms mid-season with large flowers, and is a regular and productive bearer of large to medium size, symmetrical, globose, freestone fruit having yellow skin substantially overspread with red, and yellow flesh with red next to the stone; the variety being particularly characterized, as to novelty, by fruit which--while generally resembling the clingstone fruit of the Le Grand--is freestone, and ripens a few days later.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is an illustration, by photographic reproduction in color, of a twig with leaves, and separate fruit; one of the latter being halved to show the flesh, and the stone remaining in one of the halves.
