Botanical classification: Prunus persica.


The new peach tree (hereinafter referred to as the ‘P.F. Big George’) was originated by Paul Friday in the experimental orchard, which is maintained for the purposes of breeding peach trees, located in Coloma, Mich. Coloma is located in the southwest section of Michigan, USDA Hardiness Zone 6A, with observed temperature ranges of minus 12 degree Fahrenheit to 90 degree Fahrenheit, also with annual rainfall of about 40 inches.

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 there 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. Big George’, was a single plant from one such 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 an experimental orchard 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 asexual propagation.


The new and very distinct variety of peach tree is of average height and of upright growth and a regular and productive bearer of peaches. A distinguishing characteristic is that it is a very late maturing peach, 54 days after ‘Redhaven’ (non-patented) in southwest Michigan. The blossoms are characterized as being showy. More specifically the blossoms of ‘P.F. Big George’ peach tree have angularly spaced five-blossom petals projecting upwardly at an inclined angle so as to form a blossom, having about 1½″ diameter, measured across the blossoms. As the typical showy blossom as exemplified by ‘Loring’ (non-patented) peach.

The fruit at maturity is large, having flesh that is firm and a light yellow with red around the pit.

The skin is smooth having moderate to little down and is of dark red overlying yellow ground color. The yellow background covers approximately twelve percent (12%) 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 very late 54 days after ‘Redhaven’ (non-patented) peach in southwestern Michigan, it stores very well in a refrigerated room at 33 degree Fahrenheit for up to 3 weeks without becoming dry or mealy, remaining very sweet 15 brix of sugar. The fruit as mentioned heretofore is of dark red overlying yellow which covers approximately twelve percent (12%) 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 shows two (2) whole fruits with one bisected across the axis showing that it is freestone, and has a clear yellow flesh with red around the pit. A tape measure has been placed in the photograph showing that the fruit form 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.
