USPP15659P2 - Peach tree named “P.F. 24-C cold hardy” - Google Patents

Abstract

A new and distinct variety of peach, Prunus persica, tree having the following unique combination of desirable features:

• • 1. Producing a bud that is particularly winter and spring cold hardy.
  • 2. The limbs of the tree naturally grow at wide angles creating a wide-spreading tree.
  • 3. A fruit with a smooth raised suture that remains firm as does the whole fruit.
  • 4. A late maturing, highly colored, peach cultivar that matures a few days before the old standard variety, “Cresthaven” (unpatented), and which hangs on the tree for many days, staying extremely firm.

Description

Botanical classification: Prunus persica.

ORIGIN OF VARIETY

The new peach tree {hereinafter referred to as the ‘P.F. 24-C cold hardy’ 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. 24-C cold hardy’, 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.

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

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree is of average height and of spreading growth and a regular and productive bearer of peaches. A distinct characteristic of the “P.F. 24-C cold hardy” peach tree is its medium vigor having a growth of about eighteen inches (18″) per year. The blossoms bloom in mid-season and are characterized by being contracted or partially spread to approximately ⅝-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 ⅝-inch measured across the blossoms.

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

The skin is smooth having moderate to little down and is of dark red color overlying a yellow ground color. The yellow background covers approximately thirty percent (30%) 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 dark red color overlying a yellow which covers approximately Thirty percent (30%) of its surface and has a very attractive appearance.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The top photograph shows the leaves of the plant both upper and lower side.

The bottom photograph shows two (2) whole peaches of this cultivar depicting dark red skin color for fruit maturing so late in the season. The middle fruit 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 is the desirable ratio of the size of the stone to the fruit size of this tree. A ruler has been placed in the photograph showing the large size of the fruit.

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