Peach tree (N30-12E)

Abstract

A peach tree which is medium size, medium vigorous, upright-spreading, hardy, foliated with medium size, lanceolate leaves having a crenate margin, medium length petiole, and globose glands, blooms prolificly from hardy, medium-small, conic-pointed flower buds free from the stem and moderately pubescent, the flowers being large, showy, and pink; and is a regular and very productive bearer of large, uniform, globose, symmetrical, clingstone fruit having tough, thick, tenacious-to-flesh, yellow skin having a red blush, and fine, moderately firm, non-melting, light orange-yellow flesh.

Description

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.

BACKGROUND OF THE VARIETY

1. Field of the Invention

The inventor, Luther D. Davis, in the conduct of an extensive plant breeding program, originated a substantial number of new and distinct varieties of fruit trees, and which included the herein-claimed variety of peach tree. Such plant breeding program was undertaken by inventor Luther D. Davis at the University of California, Davis, Yolo County, Calif., and particularly in the experimental orchard at such location.

2. Prior Varieties

Among existing varieties of peach trees known to inventor Luther D. Davis, particular reference is made to Gaume (unpatented) and Carolyn (an unpatented selection of the U.S. Department of Agriculture) hereinafter mentioned for the purpose of comparison.

ORIGIN OF THE VARIETY

The present variety of peach tree was originated by inventor Luther D. Davis in the aforesaid experimental orchard, as a cross between two unnamed peach seedlings, which bore the identifications GH 8-14 and D30-3E.

ASEXUAL REPRODUCTION OF THE VARIETY

Subsequent to its origination, the present variety of peach tree was asexually reproduced, on behalf of inventor Luther D. Davis, and by budding on peach seedling rootstock, by a commercial nursery. Such asexual reproductions, in maturity at certain test plots, ran true to the original tree of the variety in all respects.

SUMMARY OF THE VARIETY

The present variety of peach tree is medium size, medium vigorous, upright-spreading, hardy, foliated with medium size, lanceolate leaves having a crenate margin, medium length petiole, and globose glands, blooms prolificly from hardy, medium-small, conic-pointed flower buds free from the stem and moderately pubescent, the flowers being large, showy, and pink; and is a regular and very productive bearer of large, uniform, globose, symmetrical, clingstone fruit having tough, thick, tenacious-to-flesh, yellow skin having a red blush, and fine, moderately firm, non-melting, light orange-yellow flesh.

The present variety of peach tree is characterized by fruit which--while slightly resembling the Gaume--is distinctive, in comparison, by absence of blossom end breakdown, by a larger stone less likely to split, and by a higher flavor fresh and canned.

The present variety of peach tree is further characterized by fruit which--enhanced by its large size and high flavor--processes into a very attractive canned peach; the fruit being in harvest approximately three days ahead of the Carolyn.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is an illustration, by photographic reproduction in color, of separate fruit of the variety; one fruit being half cut away and the stone removed to show the flesh and the pit cavity. The drawing also illustrates separate stones of the variety.
