Description

ORIGIN OF VARIETY

The new peach tree (hereinafter referred to as the P.F. 27A 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. 27A, was a selection from one such a 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 comprehensive, the details of the botanical description to follow are believed to be a reasonably complete botanical description of the tree of this disclosure.

ASEXUAL REPRODUCTION OF THE VARIETY

The new and distinct variety of peach tree was asexually propagated by budding as performed in the experimental orchard of Paul Friday Farms Inc., located 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 propagation.

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree is of semi-dwarf, moderate upright growth and a regular and productive bearer of peaches. A distinct characteristic of the P.F. 27A peach tree is its medium vigor having very stubby new growth with short internodes. The buds are generally 1 inch apart on the new growth. The blossoms bloom in mid-season and are characterized by being contracted or partially spread in a 3/4-inch diameter during full bloom. At the same time the petals of the blossoms are of lesser length than the length of petals of the normal showy blossom as exemplified by the Loring peach blossom.

The blossoms of the present peach tree at full bloom may be characterized as being non-showy. More specifically, the blossoms of the present peach tree have radially projecting and angularly spaced five blossom petals to form a blossom having a diameter of about 3/4" measured across the blossoms.

The flesh of the fruit of the present peach tree is firm and is yellow.

The skin is smooth having moderate to little down and is of dark red color over about sixty percent to eighty percent (60% to 80%) of its surface at maturity. The red color overlays yellow. Where the red merges with the yellow, the yellow is mottled with the red to a clear light yellow. At maturity the peach is spherical having an average diameter of about 23/4".

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 bruising and soft blemishes which lead to rejection by the buyer in the fresh market in peaches of the commercial varieties. The firmness of the 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 latter part of the peach growing season of southwestern Michigan. The fruit as mentioned heretofore is of red color over about sixty percent to eighty percent (60% to 80%) of its surface and has a very attractive appearance.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

In the accompanying photographic illustrations, the top photograph shows a stem of the tree taken at ripeness of fruit and harvest stage.

This photograph shows three whole specimens of fruit at different orientations while still attached to the stem, as well as one specimen of the fruit bisected at a ninety-degree angle to the plane of the suture, with the stone retained in the half at the top. The color of bearing wood, top and bottom leaf surfaces, leaf midribs, fruit skin color and patterns of coloration, fruit flesh color and color of flesh adjacent to the pit cavity are illustrated.

The bottom photograph depicts a typical stem of the tree at a stage near full bloom, with newly emerging leaves. The branching shown is typical and reflective of branch density on bearing portions of the tree. Flower density and character are depicted at anthesis.

DESCRIPTION OF VARIETY

The detailed botanical description of the foliage and fruit of the new variety of peach tree is based upon observations of the specimens grown at Coloma, Mich. with the color terminology, other than the terminology expressed in common terms, in accordance with the Panatone Matching System (PMS) as used internationally to identify printed colors.
