`FA 59` peach tree

Abstract

A new peach variety, Prunus persica, (hereinafter referred to as the `FA 59` peach tree) which was developed by Annette and Randy Bjorge in a breeding program at Fruit Acres Farm in Coloma, Mich., having the following combination of unique and desirable features:1. A very large, substantially round fruit with clear yellow flesh and very attractive orange-red stripe over a red blush covering 80% of the fruit at maturity.2. A fruit maturing 20 days later that the `Redhaven` peach.3. A fruit with flesh that does not brown when cut.4. A fruit with excellent shipping and storage qualities.5. A fruit that ripens with multiple pickings and produces heavy tonnage per acre.

Description

ORIGIN OF THE VARIETY

The new variety of peach tree `FA 59` was developed by Annette and Randy Bjorge in a peach breeding program at Fruit Acres Farms, 2559 Friday Road, Coloma Mich. 49038. The `FA 59` peach tree was developed as a first generation cross between `Fayette` and `SH 426`. `Fayette ` being an established, non-patented, commercial variety and `SH 426` being a numbered test variety from the South Haven Research Station, South Haven Mich. This research facility is no longer in operation. The parent tree was grown and maintained in a peach tree breeding orchard on Fruit Acres Farms. This new and distinct variety of peach tree has been asexually propagated by budding at Fruit Acres Farms in Coloma, Mich. The asexual propagation demonstrates that such reproduction of the characteristics of the tree are consistent and are established and transmitted through succeeding generations.

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree is of large, open, upright growth with medium density and is a regular and very productive bearer of peaches. The new variety produces very large fruits that ripen with multiple pickings and produce a high per acre tonnage. The fruit of the new variety is characterized by very large, round, freestone, substantially 80% orange-red fruits with a mottled striping pattern on the exposed parts of the fruit that bleed into a glowing red blush. The fruits have firm flesh and are resilient to the extent that they may be handled and packaged mechanically without damaging the same for shipment. This results in less spoilage and a greater market value. The flesh of the fruits of the new variety does not brown when cut. The fruits of the new variety have a recessed pistil point which avoids damage during picking and handling. The tree and fruits of the new variety exhibit good resistance to Bacterial Spot and are very cold hardy. The fruit matures in the middle of the peach growing season in Southwestern Mich. It ripens 20 days after the established commercial variety, `Redhaven`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show typical specimens of the new variety in color as nearly true as it is reasonably possible to make the same in color illustrations of this character. The specimens were photographed in Van Buren and Berrien counties of Southwestern Mich.
