Peach tree (B-41871)

Abstract

A new and distinct variety of peach tree which is large, vigorous, upright, spreading and hardy under California conditions; foliated with medium to large, lanceolate leaves having a crenate to finely serrate margin, and alternate globose glands; and is a regular and productive bearer of large, early ripening, uniform, semi-freestone, very slightly asymmetrical fruit globose in apical aspect and globose to slightly ovoid in lateral aspect, the fruit having straw-yellow ground color blushed with red, and yellow-amber flesh color.

Description

BACKGROUND OF THE VARIETY

Field of the Invention

As an owner of a ranch, including orchards, located near Reedley, Fresno County, Calif., I frequent such ranch and orchards for the purpose of inspection, and the supervision of soil cultivation, irrigation, and harvesting of crops. Against this background of my activities, the present variety of peach tree was discovered by me.

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.

PRIOR VARIETIES

Among existing varieties of peach trees which are known to me is the Maycrest (U.S. Plant Pat. No. 4,064), and which variety is mentioned herein for the purpose of comparison.

ORIGIN OF THE VARIETY

The present variety of peach tree was discovered by me in an orchard of Maycrest trees on my ranch located aforesaid; my discovery of the present variety having been made during routine orchard operations and just prior to harvest of the Maycrest trees. During such operations, I recognized that one tree in the orchard was distinctive in several respects. I subsequently maintained such tree under close, regular and continued observation; such observations having confirmed the distinctive characteristics of the present variety of peach tree--and which is believed to be a whole tree mutation of the Maycrest. I, therefore, determined to asexually reproduce the present variety of peach tree with a view toward the ultimate commercial growth thereof.

ASEXUAL REPRODUCTION OF THE VARIETY

The present variety of peach tree was asexually reproduced, under my direction, by budding on existing and compatible peach rootstock; such reproductions having been undertaken in my orchard, located as aforesaid, and in maturity the reproductions ran true in all respects to the original tree.

SUMMARY OF THE VARIETY

The present variety of peach tree is large, vigorous, upright, spreading and hardy under California conditions; foliated with medium to large, lanceolate leaves having a crenate to finely serrate margin, and alternate, globose glands; and is a regular and productive bearer of large, early ripening, uniform, semi-freestone, very slightly asymmetrical fruit globose in apical aspect and globose to slightly ovoid in lateral aspect, the fruit having straw-yellow ground color blushed with red, and yellow-amber flesh color.

The present variety of peach tree is further, and more particularly, characterized--in comparison to the Maycrest--by more vigorous tree growth; by above average uniformity of fruit distribution on the tree; by more advancement of the external color of the fruit in the early stages of ripening; and by ripening to picking maturity, of the semi-freestone fruit, approximately six days earlier. When both the Maycrest and the present variety reach maturity on their respective ripening dates, their external appearance is quite similar.

BRIEF DESCRIPTION OF THE DRAWING

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