"August White" peach tree

Abstract

A new and distinct variety of peach tree which is somewhat remotely similar to the "Champagne" peach tree (U.S. Pat. No. P.P. 4,865) of which it is a sport, but from which it is distinguished by producing fruit which are mature for harvesting and shipment approximately eight (8) days to two weeks after the fruit produced by the "Champagne" peach tree and wherein the fruit has more flavor and a white flesh coloration.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of peach tree, which will hereinafter be denominated varietally as the "August White" peach tree, and, more particularly, to a peach tree which produces freestone fruit, which are mature for commercial harvesting and shipment approximately August 20 to August 31, or about eight (8) days to two (2) weeks after the fruit of "Champagne" peach tree, in the San Joaquin Valley of central California.

The discovery and commercialization of new plant varieties, particularly of new varieties of fruit trees, is a process which is fraught with risk, both to the developer as well as to others involved in the process. This is certainly the case in regard to new peach varieties, in part because of the multiplicity of existing peach varieties. The investment in time and expense required in such development is enormous and is entirely contigent upon the assessment of those involved in the process as to the value of the new variety for commercialization. If a positive assessment proves to be without foundation, the loss to those involved may be considerable. Accordingly, the development of new varieties of peach trees is frequently a slow and painstaking process designed to ensure that the initial positive assessment is well founded and thus minimize the risk of loss.

The new variety of peach tree of the present invention appears to be an attractive candidate for commercialization due to its distinctive characteristics, as will hereinafter be fully set forth.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of peach tree hereof was discovered by the inventor is a peach orchard which is located at Road 44 and Brewer Dr. near Dinuba in the San Joaquin Valley of central California. The inventor discovered the new variety as a sport of the "Champagne" peach tree U.S. Pat. No. P.P. 4,865) in August of 1993. In the spring of 1994, the inventor asexually reproduced the new variety by grafting scions of the new variety containing several buds, including vegetative and flower buds on six trees of Nemagard root stock to the new variety at Kingsburg in the San Joaquin Valley of central California. These scions of the new variety produced fruit in August of 1994 which has been observed by the inventor and has similarly been observed each year thereafter. The inventor has observed the asexually reproduced trees of the new variety and confirmed that they are in all respects identical to the originally discovered sport.

SUMMARY OF THE NEW VARIETY

The "August White" peach tree is characterized by producing late ripening, freestone fruit which have white flesh with a distinctive red skin coloration on the shoulders and along the suture at maturity and which possesses an appealing flavor. The new variety is ripe for commercial harvesting and shipment approximately August 20 to August 31 in the San Joaquin Valley of central California. The new variety is most closely similar to the "Champagne" peach tree (U.S. Pat. No. P.P. 4,865), but is distinguishable therefrom by the aforemented ripening date which is after that of the "Champagne" peach tree by about eight (8) days to two (2) weeks in the San Joaquin Valley. The fruit of the instant variety is much sweeter than that of the "Champagne" peach tree.
