Peach tree named ‘MSUP8706’

Abstract

A new peach variety, Prunus persica, (hereinafter referred to as the MSUP8706 peach variety), which was developed by Amy Iezzoni and Bill Shane in a breeding program at the Southwest Michigan Research and Extension Center in Benton Harbor, Mich., having the following number of unique and desirable features: 1. A fruit with excellent shipping and storage characteristics. 2. A fruit maturing at the same season as the Loring peach (an unpatented selection). 3. A generally round fruit with freestone, yellow flesh, and an attractive red blush.

Description

Prunus persica ‘MSUP8706’.

FIELD OF THE INVENTION

The new variety of MSUP8706 peach tree was developed by Amy Iezzoni and William Shane in a peach breeding program. The MSUP8706 peach was developed as a cross between SH424 (unpatented), an experimental selection from Michigan State University and Fayette, an unpatented selection. The parent tree was grown at Clarksville, Mich. and was tested as MSU Plot II, Row 7, Tree 26. MSUP8706 is an interspecific cross.

This new and distinct variety of peach tree has been asexually propagated by budding on Halford peach seedling rootstock in Benton Harbor, Mich. The asexual propagation demonstrates that such reproduction of the characteristics of the tree is consistent and is established and transmitted through succeeding generations.

BRIEF DESCRIPTION OF THE DRAWINGS
