Botanical classification: Prunus persica.


The new peach tree {hereinafter referred to as the ‘P.F. 36-007’ peach tree} was originated by Paul Friday in the experimental orchard, which is maintained for the purposes 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 pollinations 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. 36-007’, was a single plant from one such a seedling population, and was based on the numerous superior genetic attributes of this tree which are described in the botanical description 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.


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 characteristics of the tree are consistent and established and transmitted through succeeding propagation.


The new and distinct variety of peach tree is of average height and of upright growth and a regular and productive bearer of peaches. A distinct characteristic of the ‘P.F. 36-007’ peach tree is its medium vigor having a growth of about twenty-four inches (24″) per year. The blossoms bloom in mid-season and are characterized by being contracted or partially spread to approximately ¾-inch when in full bloom. At the same time the five petals of the blossoms are of lesser length than the length of petals of the normal showy blossom as exemplified by the ‘Loring’ (unpatented) 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 ¾-inch 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 light red color overlying a yellow ground color. The yellow background covers approximately fifteen percent (15%) of its surface at maturity. At maturity, the peach is spherical having an average diameter of about 2¾″.

The fruit produced by this tree has firm, and non-melting flesh, and thereby has the attendant resistance to blemishes and soft spots in harvesting, shipping and handling due to bruising, The firmness of the fruit flesh is sufficient to allow the flesh to yield and be restored when bumped or dropped without the resulting soft spots as would be experienced in most late season peaches of the market class. Thus, fruit of this tree remains more attractive to the ultimate buyer, the consumer, and thereby will command premium prices for late fresh desert market.

The fruit matures in the latter part of the peach growing season in southwestern Michigan. The fruit as mentioned heretofore is of light red color overlying yellow which covers approximately fifteen percent (15%) of its surface and has a very attractive appearance.


In the accompanying drawing,

The top photograph shows the leaves of the plant depicting both upper and lower sides. A tape measure is included showing the length of a leaf.

The bottom photograph depicts a whole fruit shown from the top view on the left, and a whole fruit shown from the bottom on the right. In the middle of the photograph is a peach cut in cross section showing that it is freestone, and has clear yellow flesh with red around the pit, which is also red. A tape measure has been placed in the photograph showing that the fruit from this tree has the genetic capability to exceed two and three-quarters inches (2¾″) in diameter.


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 Pantone Matching System {PMS} as used internationally to identify printed colors.
