Description

Plant Patent #17045 issued 8/22/2006. ORIGIN OF VARIETY The new peach tree (hereinafter referred to as the `P.F. 7A Freestone` peach tree) was originated by Paul Friday in an 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 annual rainfall of about 40 inches. In an ongoing mass selection breeding program, unpatented 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. 7A Freestone`, was a single plant from one such a unpatented 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 VARIETY 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 propagation. SUMMARY OF THE VARIETY The new and distinct variety of peach tree is of moderate upright growth and a regular bearer of peaches. The blossoms are characterized by being spread when in full bloom. The blossoms of the present peach tree at full bloom may be characterized as being showy. More specifically, the blossom of the present peach tree have angularly spaced five (5) petals projecting upwardly at an inclined angle so as to form a blossom having a diameter of about 11/2'' measured across the blossoms. The typical shown blossom as exemplified by the `Loring` (unpatented) peach. The flesh of the fruit of the present peach tree is firm and is yellow. The skin is smooth and is of dark color over about ninety (90%) percent of its surface at maturity. The red color occurs over about sixty (60%) percent of the surface 10 days prior to maturity. At maturity the peach is substantially spherodial with the diameter ranging between about 21/2'' and 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 permanent deformities in peaches of 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 early part of the peach-growing season of southwestern Michigan. The fruit as mentioned heretofore is of red color over about ninety (90%) percent of its spherodial surface and has a very attractive appearance.

Key

  • Evaluations are based on a 1-8 scale (6=OK,7=Commercially acceptable, 8=Excellent)
  • Size is in inches
  • Shape: round is assumed, T=tip, P=point, S=suture, OB=oblate, OV=ovate
  • Pubescence: 10=nectarine
  • Blush: presented as percentage of ground color cover with red or similar
  • Freeness: 3=early cling, 8=completely free
  • Status: 0=discard, 1=keep
  • Notes: SOS=soft on suture, SOT=soft on tip, RIF=red in flesh, GAS=green around stem
  • RAP=red around pit, GGC=green ground color, sz=size, wh=white, yt=young tree, CCT=concave tip
  • Bloom date is when approx. 90% of blooms are open (full bloom)

The description of each variety of peach or nectarine fruit under each group is in different formats as this information is collected from varied sources and hence is not consistent
