The fruit are large, round and very firm and do not bruise easily. The flesh is crisp with a clear yellow 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 `92-287` peach tree, and, more particularly, to such a peach tree which produces free stone fruit having clear yellow flesh and red pit cavity which mature for commercial harvesting and shipment approximately September 10 to September 15 in the San Joaquin Valley of central California.

Although the varieties of peach trees producing commercially acceptable fruit relatively common, it is not common to find peach varieties that produce commercially acceptable fruit at the beginning or end of the typical peach growing season. Most peaches available at the end of the growing season are usually characterized as only marginally acceptable due to various factors, including poor coloration or taste, small size and unsuitable handling abilities. New peach varieties which produce fruit at the end of the growing season that have characteristics which are found in fruit produced at or near the peak portion of the growing season are usually considered to be commercially valuable. The variety of peach tree of the present invention is such a variety, as set forth herein.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The peach tree of the present invention was discovered by the inventor as a chance seedling in a nursery located near Reedley in the San Joaquin Valley of central California. The first fruit was seen on this seedling in September of 1992. As the fruit matured, it was examined as to size, shape, coloration, ripening date, flavor, texture and as to other criteria which were sought in a peach variety having the desired commercial potential. The initial fruit had the size, shape, color and handling characteristics which the inventor was looking for in the early to mid-September date period. Specifically, the fruit was a free stone peach having clear yellow flesh and was very firm, making it easy to handle and able to ship well. The seedling was marked for further testing.

Bud wood was collected from this seedling in the Winter of 1992-1993. Seedlings were grafted onto Nenaguard rootstock in the early Spring of 1993 in the testing part of the nursery. Additional seedlings were grafted in the early Spring of 1994. The first fruit from these asexually produced trees of the new variety was observed by the inventor in September 1995.

The harvest time for the asexually produced trees of this new variety was early to mid-September, the same time as the original seedling. These trees produced the same large, round fruit having flesh of a very firm texture as that seen on the original seedling. The flavor of the fruit was very good. The flesh coloration of the fruit was the same clear yellow color. The leaves and bark matched those on the original seedling. The inventor has confirmed that the asexually reproduced trees of the new variety are the same in all respects to the original seedling.

SUMMARY OF THE NEW VARIETY

`92-287` peach tree is characterized by producing a fruit which has a yellow flesh coloration and is ripe for harvesting and shipment approximately September 10 to September 15 in the San Joaquin Valley of central California. The fruit of the new variety are approximately three (3) inches or larger in diameter and almost fully round in shape. The flavor of the fruit at harvest date is good. The fruit is crisp, but it still has good flavor. The skin of the fruit from this variety is very high color, almost full red. The flesh is full yellow with red only in the pit cavity. At harvest time this fruit is very firm, making it easy to handle and ship. The skin is tenacious to the flesh, which also helps in handling and shipping. The inventor has not seen any breakdown on the suture line, or at the base or apex area of this fruit. The fruit has been determined to have outstanding storage life, retaining its firm flesh of very good flavor even after thirty (30) days in cold storage. The inventor has kept fruit from this new variety on the shelf for a week at room temperature and it held up very well.
