Plant Patent #11630 (Nov. 7, 2000) to Zaiger Genetics of Modesto, CA. A new and distinct variety of peach tree. The features of the tree and its fruit are characterized with the tree budded on nemaguard rootstock, grown on Hanford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., and with standard commercial cultural fruit growing practices, such as, pruning, thinning, spraying, irrigation and fertilization. Its novelty consists of the following unique combination of features that are outstanding in a new variety: 1. Fruit with a high degree of attractive red skin color. 2. Fruit with the ability to remain firm on the tree 10 to 12 days after maturity (shipping ripe). 3. Fruit having firm flesh with good shipping and handling quality. 4. Fruit with sweet, sub-acid flavor and good eating qualities. 5. Heavy and regular production of large size fruit. 6. Vigorous, upright growth. A new and distinct variety of peach tree, substantially as illustrated and described, characterized by its large size, vigorous, upright growth; and a productive and regular bearer of large, clingstone fruit that has an attractive red skin color and a mild, sweet, sub-acid flavor; and the fruit is further characterized by having firm, yellow flesh with good handling and shipping qualities, and, in comparison to Sweet Scarlet Peach (U.S. Plant Pat. No. 9,695), the fruit of the new variety is approximately 18 days later in maturity. The present new variety of peach tree was originated by us in our experimental orchard located near Modesto, Calif., as a first generation cross between two selected seedlings with field identification numbers 39EB706 and 34GA1155. The maternal parent (39EB706) originated from a cross between two selected seedlings, 32EA300 and 11E284. The seedling selection 32EA300 originated from a cross between O'Henry Peach (U.S. Plant Pat. No. 2,964) and Giant Babcock Peach (U.S. Plant Pat. No. 1,353). The seedling selection 11E284 originated from seed of an open pollinated Red Grand Nectarine (U.S. Plant Pat. No. 1,060). The pollen parent (34GA1155) originated from a seedling selection from an open pollinated May Grand Nectarine (U.S. Plant Pat. No. 2,794) crossed with a peach of unknown parentage. A large number of these first generation seedlings growing on their own root were planted and maintained under close observation, during which time one such seedling evidenced desirable tree and fruit characteristics and was selected for asexual propagation and commercialization.


  • 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
