A new and distinct variety of peach tree which is somewhat remotely similar to the "Elegant Lady" peach tree (U.S. Plant Pat. No. 4,399) and the "O'Henry" peach tree (U.S. Pat. No. 2,964), but from which it is distinguished by producing fruit which is mature for harvesting and shipment approximately July 22 to August 5 in the central San joaquin valley of california, the fruit being freestone having an oval shape and which further exhibits a highly colored and very firm light yellow flesh.

1. A new and distinct variety of peach tree substantially as illustrated and described which was derived as a spontaneous mutation of the "Spring Red" nectarine tree (U.S. Plant Pat. No. 3,619) and which is somewhat remotely similar to the "Elegant Lady" peach tree (U.S. Plant Pat. No. 4,399) and the "O'Henry" peach tree (U.S. Plant Pat. No. 2,964), but from which it is distinguished by producing a freestone fruit which is mature for harvesting and shipment approximately July 22 to August 5 in the San joaquin valley of central california, the fruit having from an orange-red to a deeper garnet-red coloration having substantial light colored speckles present and a flesh which is a light amber-yellow and of a very firm texture at commercial maturity.

The present invention relates to a new and distinct variety of peach tree, which will hereinafter be denominated varietally as the "Special Red July" peach tree, and, more particularly, to such a peach tree which produces freestone fruit which is mature for commercial harvesting and shipment approximately July 22 to August 5 in the San Joaquin Valley of central California, and which is further distinguished by the fruit being large, highly colored, productive and very firm and which hangs well on the tree so that it can be harvested over an extended two week period.
The discovery and development of new commercial varieties of fruit is a science dependent upon many years of observation of the myriad of individual characteristics of a multitude of varieties, a full knowledge of the critical characteristics of the best existing commercial varieties, a knowledge of the markets for the fruit thereof and a substantial amount of good fortune. Since the value of new varieties of fruit bearing trees is largely dependent upon the commercial acceptance of the fruit thereof, those attributes which enhance the attractiveness of the fruit to consumers generally receive the greatest scrutiny. Thus, size, coloration, flavor and the like are very important. Perhaps less obviously, but of equal importance, are such attributes as ripening time, productivity, holding quality, resistance to damage and resistance to disease and to pests. These qualities are of significance in ensuring that the fruit can be made available to the consumer at the best time, in the best possible condition and in commercially practical volume.
The fruit of the "Special Red July" peach tree of the subject invention possesses an unusually attractive combination of many of these commercial attributes. As will hereinafter be described in greater detail, the peach tree of the subject invention produces large, highly colored fruit having unusually firm flesh with superior holding qualities and ripening during a time period complementing existing commercial varieties.
The "Special Red July" peach tree was discovered by the applicant as a spontaneous mutation of the "Spring Red" nectarine tree (U.S. Plant Pat. No. 3,619) on the applicant's property in Orosi in the central valley of California. The discovery took place on May 10, 1988 when the applicant noted the distinctive characteristics hereinafter to be described. The applicant asexually reproduced the new variety in January, 1989 by grafting wood taken from the spontaneous mutation, appearing as a small hangar-like limb occurring at a height of approximately seven feet from the ground on the parent tree, on to a "Spring Red" nectarine tree on the same property. The applicant has continued to observe the asexually reproduced peach tree of the new variety and has confirmed that it has the same distinctive characteristics as the original spontaneous mutation.
The peach tree is characterized as to novelty by producing a very firm fleshed freestone fruit which has a deep garnet red coloration with substantial light colored speckles present. Further, the fruit produced by the "Special Red July" peach tree is ripe for commercial harvesting and shipment approximately July 22 through August 5 in the San Joaquin Valley of central California. The variety is most closely similar to the "Elegant Lady" peach tree (U.S. Plant Pat. No. 4,399) and the "O'Henry" peach tree (U.S. Plant Pat. No. 2,964), but is distinguishable therefrom and characterized principally as to novelty by producing fruit which are ripe for harvesting and shipment approximately two weeks after the "Elegant Lady" peach tree and approximately one week before the "O'Henry" peach tree. The instant variety produces a fruit with a blush color which is generally darker and slightly more dull than that of the "Elegant Lady" peach tree and has more speckling and russets than is found on either the "O'Henry" or the "Elegant Lady" peach trees.
The accompanying drawing is a color photograph showing a branch with typical foliage of the new variety bearing two whole fruit thereof, a second fruit of the new variety shown in side elevation, a third sectioned and with the stone removed to expose the pit well, a fourth sectioned with the stone left in place and two stones, all of the new variety.

Although the new variety of peach tree possesses the described characteristics noted above as a result of the growing conditions prevailing near Orosi, Calif. in the central part of the San Joaquin Valley of California, it is to be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, irrigation, fertilization, pruning and pest control are to be expected.
