Peach tree named `R1-T2`

Abstract

A new and distinct variety of peach tree, designated `R1-T2`, originated as a seedling in a block of `John Boy`. It is a midseason variety maturing 5 to 7 days after `John Boy` and 5 to 7 days before `Loring`. The fruit is yellow-fleshed, freestone, large sized, and flavorful. The surface of the fruit is 70 to 80% attractive orange-red over a yellow-orange background.

Description

BACKGROUND OF THE DISCLOSURE

This invention relates to peach trees and, more specifically, to peach trees referred to as a variety of Prunus persica Batsch.

I discovered this new and unique variety of peach tree as a seedling growing in a row of `John Boy` (U.S. Plant Pat. No. 6,827) in a cultivated area near Aspers, Pa. The tree of this invention produces a fruit of attractive commercial value, ripening after `John Boy` and before `Loring`(unpatented).

This new variety of peach was asexually reproduced by grafting near Aspers, Pa. and such reproduction has shown this new variety to come true in two successive generations. This propagation of the new variety by grafting under standard controlled conditions clearly discloses the continued maintenance of the characteristics described herein which distinguish this new variety from the parent variety and other related varieties of peach trees.

SUMMARY OF THE INVENTION

This new and distinctive variety of peach tree produces a yellow-fleshed, freestone fruit that is attractively colored, large, firm and flavorful. It ripens prior to `Loring` and after `John Boy`, two midseason varieties grown in the Mid-Atlantic region. The fruit has a full red blush that is more attractive than `Loring` and similar to `John Boy`. The tree is vigorous and has a regular bearing habit.

DESCRIPTION OF THE DRAWINGS

This new variety of peach tree is illustrated by the accompanying photographic drawings and depicts the plant by the best possible color representation using color photography.

FIG. 1 is a close-up which depicts one specimen of fruit of the new tree, reflecting the characteristic shape, size and red blushed skin color over a contrasting yellow ground color. Also shown is the pistil point and suture of the fruit of this new tree.

FIG. 2 depicts, at the top left, a whole specimen of the fruit shown from the stem end; at the middle left, a whole specimen of fruit from the apex; on the bottom left, a partially dissected fruit; on the right, a branch showing current season's growth, leaves, leaf arrangement and leaf spacing; and below, a ruler to reflect the scale of the plant parts.

FIG. 3 shows a second generation, 4-year-old tree, illustrating typical tree form and productivity.
