Burpeachsix was patented 12/24/2002 by The Burchell Nursery, Inc., Oakdale, CA. It is patent #13392.
BACKGROUND OF THE NEW VARIETY. The present invention relates to a new, novel and distinct variety of peach tree, Prunus persica which has been denominated varietally as `Burpeachsix`. The `Burpeachsix` Peach Tree produces an exceptionally high quality, peach which is mature for harvesting and shipment in the mid-season. Still further, another unique aspect of the `Burpeachsix` is that it yields a very firm peach that has a high eating quality as compared with the other peach varieties which ripen at approximately the same time of the season. ORIGIN OF THE NEW VARIETY. The present variety of peach tree resulted from an on-going program of fruit and nut tree breeding. The purpose of this program is to improve the commercial quality of deciduous fruit and nut varieties and rootstocks by creating and releasing promising selections of prunus, malus and regia species. To this end, we make both controlled and hybrid cross pollinations each year in order to produce seedling populations from which improved progenies are evaluated and selected. The seedling `Burpeachsix` was originated by us in 1994, and was chosen from among a population of seedlings which resulted from a controlled cross pollination of the `Grand Diamond` Nectarine Tree (U.S. Plant Pat. No. 4,095), which was used as the pollen parent, and the `July Lady` Peach Tree (U.S. Plant Pat. No. 3,023), which was used as the seed parent. The resulting seed from this cross was planted in the spring of 1995. The new variety was selected from among seedlings growing in experimental orchards near the city of Fowler, Calif., County of Fresno, in the Central San Joaquin Valley. The Peach Tree `Burpeachsix` was subsequently marked and noted as having exceptional characteristics. After the 1996 season, the Peach Tree `Burpeachsix` was selected for advanced evaluation and repropagation. It has been subsequently evaluated during the 1996-1999 fruiting seasons. ASEXUAL REPRODUCTION. Scionwood from the original seedling of the Peach Tree, `Burpeachsix` was collected and grafted in the evaluation plot in the experimental orchard previously described onto two different and existing `Nemared` (unpatented) rootstocks in February of 1997. The resulting propagation (fruit and scion) have been subsequently evaluated in the 1998 and 1999 seasons. These evaluations clearly demonstrated that the repropagated trees are true to the fruiting and vegetative characteristics of the original seedling in all observable aspects. SUMMARY OF THE VARIETY. The `Burpeachsix` Peach Tree is characterized as to novelty by producing fruit which have a mid-season ripening date, and which are further of high quality, firm, and have an attractive exterior coloration. In this regard, the present variety of peach tree bears freestone fruit which are ripe for commercial harvesting and shipment on approximately June 18 to June 25. These harvesting dates are approximately one week later then the harvesting dates of the commercial freestone peach variety `Red Top` Peach Tree (U.S.D.A. nonpatented). The present variety distinguishes itself from the `Red Top` Peach Tree, however, by producing fruit having a brighter and more extensive exterior coloration, and which has a firmer flesh. Further, the Burpeachsix Peach Tree distinguishes itself from the Red Top Peach Tree in that the fruit of the Burpeachsix Peach Tree has a keeping quality after it is harvested, that is superior in relative comparison to the fruit produced by the `Red Top` Peach Tree.
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
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
