Plant Patent #08169 issued 3/9/1993. ORIGIN OF VARIETY The new variety of peach tree (hereinafter referred to as the P.F. 17 peach tree) was originated by Paul Friday in the experimental orchard maintained for the purpose of breeding of Paul Friday Farms Inc., located in Coloma, Mich. Coloma is located in the southwest section of Michigan. The P.F. 17 peach tree was developed in a first generation cross between two seedlings. The female parent and the male parent are each deliberately selected ones of peach trees of unknown origin grown in the experimental peach tree breeding orchard of the Paul Friday Farms Inc. The male and female seedling were grown at the Paul Friday Farms Inc. 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 moderate upright growth and a regular and productive bearer of peaches. The blossoms are contracted or partially spread when in 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. The blossoms of the present peach tree at full bloom may be characterized as being partially showy; i.e., neither non-showy such as the Redhaven or showy such as the Loring peach blossom. More specifically, the blossoms of the present peach tree have radially projecting and angularly spaced five blossom petals projecting upwardly at an inclined angle so as to form a blossom having a diameter of about 3/4 measured across the blossoms. This partially showy blossom is in contrast to the showy blossom of the Loring peach type wherein the blossom petals are substantially flat and the diametrical measurement across the free outer edges of the petals is about 1-7/16". The typical non-showy blossom as exemplified for example by the Redhaven peach has five (5) radially extending and angularly spaced petals projecting upwardly at a relatively steep inclined angle so that the diametrical measurement across the outer edges of the petals is about 1/2". 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 eighty (80%) percent of its surface at maturity. The red color occurs over about sixty (60%) percent of the surface about 10 days prior to maturity. At maturity the peach is substantially spheroidal with the diameter ranging between about 21/2 to 3 inches. 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 deformaties 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 eighty (80%) percent of its spheroidal surface and has a very attractive appearance.


  • 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
