Description

ORIGIN OF VARIETY
The new peach tree (Prunus persica) (hereinafter referred to as the P.F. 20-007 peach tree) was originated by Paul Friday in the experimental orchard, which is maintained for the purpose of breeding peach trees, at Paul Friday Farms Inc., located in Coloma, Mich. Coloma is located in the southwest section of Michigan.
In an ongoing mass selection breeding program, superior seedlings of unrecorded parentage are maintained as seed sources for the production of seeds which are collected and planted in mass. The seed producing parent trees are maintained solely as proprietary trees for breeding purposes and have not been released from the experimental orchard, where such trees can be evaluated for their adaptability to local and regional growing conditions. Seeds resulting from open pollination of the trees in the experimental orchard are regularly planted in mass to produce new populations of seedlings which are cultured and monitored to maturity. Trees with superior attributes are retained for further observation and testing, and contribute seeds to advancing generations of new populations of seedlings.
The tree of this application, P.F. 20-007, was a selection from one such cultivated seedling population, and was based on the numerous superior genetic attributes of this tree which are described in the botanical descriptions to follow. While not exhaustive, the botanical descriptions to follow are believed to represent a reasonably complete botanical description of the new peach tree which is sufficiently detailed to distinguish the tree from the most closely related trees within the same market class.
ASEXUAL REPRODUCTION OF THE VARIETY
The new and distinct variety of peach tree was asexually propagated by budding onto ‘Bailey’ rootstock as performed in the experimental orchard of Paul Friday Farms Inc., located in Coloma, Mich. The so stated propagation demonstrates that such reproduction of the characteristics of the tree are consistent and are established and transmitted through succeeding propagation.
SUMMARY OF THE VARIETY
The new and distinct variety of peach tree is of moderate spreading growth. A distinct characteristic of the P.F. 20-007 peach tree is that it has large, strong right angle branching to support its heavy crops of large fruit. While fruit set is medium, this variety yields very big crops due to large fruit size, providing extraordinary yields and is a regular and productive bearer of large peaches.
The blossoms of the present peach tree bloom in mid-season and are characterized as being non-showy and do not open much past a vertical state only, opening to a diameter of about ½ inch diameter during full bloom with its pistil protruding beyond the plane of the opened blossom petals.
The fruit at maturity has crisp flesh of very clear yellow with red around the pit.
The skin is smooth, having little down, and is sixty to eighty percent red or more overlying medium-yellow color. At maturity, the peach is spherical, having an average diameter ranging between 2½ inches to 3 inches.
The fruit has a firm flesh and may be described as resilient to the extent that the flesh is yieldable and restorable to its original state when subjected to impact forces which may cause permanent deformities in peaches of commercial varieties. The firmness of fruit facilitates handling and packaging of the peaches without damaging the same for shipment. This results in less spoilage and also increases the shelf life.
The fruit matures in the mid-part of the peach growing season in southwestern Michigan.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
In the accompanying photographic illustrations, the first photograph was taken at a maturity stage of firm ripeness and demonstrates a typical fruit positioned to show the blossom end exhibiting the round to slightly oblate fruit shape and the exceptional symmetry of the fruit. The color of the extensive solid blush and slightly mottled over-color patterns are depicted over the ground color of the fruit skin. Shown also is a fruit that has been split on a plane ninety degrees to the suture plane to depict the fruit flesh in cross-section. The conformance of the pit cavity is illustrated, as well as the desirable ratio of the size of the stone to the fruit size of this tree. The clear flesh texture, yellow color, and red around the pit are also demonstrated.
The second photograph depicts the stem end of the fruit showing its short stem cavity and the limb imprints, demonstrating how tightly the fruit grows to the tree. Predominant smooth red color over yellow is also shown.
The third photograph demonstrates stems of current season's growth at a stage of about harvest season. It also shows young stem coloration, the top side of leaves, the shape, color and character of leaves, and the internode length.
DESCRIPTION OF VARIETY
