Plant Patent #08164 issued 03/02/1993. ORIGIN OF VARIETY The new variety of peach tree P.F. 23 was originated by Paul Friday in the experimental orchard of maintained for the purpose of breeding Paul Friday Farms Inc. located in Coloma, Mi. Coloma is located in the southwest section of Michigan. The P.F. 23 peach tree was developed in a first generation cross between two seedlings. The female parent and the male parent originated from deliberately selected ones of peach trees of unknown origin grown in the peach tree breeding orchard of Paul Friday Farms Inc. for about 8 years. The seedlings were grown in the experimental orchard of 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, Mi. 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 large spreading growth and a regular and productive bearer of peaches. The blossoms are characterized by being contracted or partially open when in full bloom so as to be capable of being described as partially non-showy. 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 blossom. The blossoms of the present peach tree are clearly distinguishable from the non-showy blossom of the Redhaven peach tree and showy blossom of the Loring peach tree. The typical non-showy as represented by the Redhaven includes five relatively short petals angularly spaced and radially projecting upwardly from the blossom base. The diametrical distance across the blossoms between the petal edges is about 1/2 inch. The typical showy blossom as exemplified by the Loring peach blossom includes five petals of substantial greater length and being angularly spaced and radially projecting normal to the base to form what may best be described as a generally flat blossom or flower. The diameter of the Loring blossom or flower taken between the outer edges of the petals is about 1-7/16 inches. In contrast, the blossoms of the present tree include five petals each of which are somewhat but distinctively curled about their lengthwise axis in the form of an elongate concave cup. The cup-shaped petals are angularly spaced and project upwardly from the blossom base. The diameter of the blossom taken between the edges of oppositely disposed petals is about 13/16 inch. 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 deformation 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 80% 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
