Abstract

A new peach variety, Prunus persica, (hereinafter referred to as the FA 18 peach tree) which was developed by Annette and Randy Bjorge in a breeding program at Fruit Acres Farm in Coloma, MI, having the following combination of unique and desirable features:1. A fruit with excellent shipping and storage qualities.2. A fruit maturing 30 days later than the `Redhaven` peach.3. A substantially round peach with white flesh and an attractive deep pinkish-red blush over a pinkish-white background covering 90% of the fruit at maturity.4. A fruit with flesh that does not brown when cut.5. A fruit and tree with resistance to Bacterial Spot.6. A fruit and blossom that is very hardy.

Description

ORIGIN OF THE VARIETY

The new variety of peach tree FA 18 was developed by Annette and Randy Bjorge in a peach breeding program at Fruit Acres Farms, 2559 Friday Road, Coloma, Mi. 49038. The FA 17 peach tree was developed as a first generation cross between `Fayette` and `Newhaven`, two established, non-patented, commercial varieties. The parent tree was grown and maintained in a peach tree breeding orchard in 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 demonstrated 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, vigorous, upright growth with medium density and is regular and productive bearer of peaches. The fruit of the new variety is characterized by its round, high shouldered, substantially 80% deep pinkish-red fruits with white flesh that present a very attractive appearance. 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 exhibits resistance to Bacterial Spot. The fruit matures in the middle of the peach growing season in Southwestern Michigan. It ripens 30 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 photograhed in Van Buren and Berrien counties of Southwestern Michigan.

FIG. 1 illustrates specimens of the fully ripened fruit and foliage of the new variety.
