The new variety is attractive commercially for its narrow columnar canopy, productivity and for fruit of excellent quality. The tree is suitable for high-density plantings, home garden and ornamental purposes. Columnar trees were first reported from Japan where they had been developed as ornamentals. Fruit quality of the original columnar trees (also known as “pillar” or “broomy” trees) was very poor. Breeding programs were thus begun in order to improve fruit quality. The new variety was originated at the Appalachian Fruit Research Station, Agricultural Research Service, U.S. Department of Agriculture in Kearneysville, W. Va. and was identified as KV930455. It was patented in 2004 (Plant Patent No. 15216). It resulted from hand pollination of peach seedling identified as KV881465 (unpatented) with pollen from peach MA6-1-90 (unpatented). KV881465 resulted from hand pollination of ‘Flavortop’ nectarine (unpatented) with pollen of “pillar” peach. MA6-1-90 was a seedling from a cross of (‘Suncrest’×K2, unpatented)דpillar”. The “pillar” pollen used in these crosses was obtained from Italy and is not patented. MA6-1-90 was obtained from the Instituto Sperimentale per la Frutticoltura, Forli, Italy. The new variety was selected in 1996 from a group of 77 seedlings produced from the pollination described hereinabove. The new variety is distinct from its parents in its combination of high fruit quality and columnar growth habit. Both parents were upright but not columnar, with fruit of moderate quality. It is distinguished from its parents as well as other peach varieties by a distinctly columnar growth habit with branch angles from the main axis at approximately 35-40°, in contrast to branch angles of standard peach trees which average approximately 60° and upright trees which average approximately 42-51°. Fruit are melting-flesh, dessert type. Fruit flesh is yellow, flavorful and firm until full-ripe. Fruit have yellow ground color with red blush that covers approximately 80% of the fruit surface. Fruit size averages 69-72 mm in diameter and 179 g in weight. Fruit are sweet with a good balance of acidity. Brix of firm-ripe fruit averages between 11.5 and 13°, depending on date of harvest. Fruit maintains firmness on the tree and in storage at levels comparable to commercial peach cultivars. From Adams County Nursery.


  • 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
  • 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
