Peach tree named Weiser

A new and distinct variety of peach tree, named ‘Weiser’, originated as a limb sport on a ‘Bellaire’ tree. It is a midseason variety maturing five days after Loring and seven to 10 days after ‘Bellaire’. The fruit has an attractive bright yellow-flesh, and is freestone, large sized, and flavorful. The surface of the fruit is uniformly attractive orange-red over a yellow background.

Latin name genes and species—Prunus persica.

Variety name: Weiser.


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

I discovered this new and unique variety of peach tree as a limb mutation on a ‘Bellaire’ tree (not patented) in a cultivated area near York Springs, Pa. The tree of this invention produces a fruit of attractive commercial value, ripening a week to 10 days after ‘Bellaire’ and five days after ‘Loring’ (not patented).

This new variety of peach was asexually reproduced by grafting rootstock—‘Lovell’ (not patented) 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.


The new and distinctive variety of peach tree produces a yellow-fleshed, freestone fruit that is attractively colored, uniformly shaped, large, exceptionally firm and flavorful. It ripens after ‘Bellaire’ and ‘Loring’, during an advantageous harvest window for the Mid-Atlantic fruit-growing region. The fruit has a red blush that is more attractive than ‘Loring’ and covers a greater portion of the fruit surface than ‘Bellaire’. The tree is vigorous, drought tolerant and has a regular bearing habit.


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

FIG. 1 is a close-up which depicts 1 specimen of fruit on the new tree, reflecting the characteristic size, shape and red blushed skin color over a contrasting yellow ground color.

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

FIG. 3 shows a third generation, 4-year old tree, illustrating typical tree form, size and growth habit.
