`Bev's red` peach tree

Abstract

A new and distinct variety of peach tree which is somewhat remotely similar to the "Topcrest" peach tree of which it is mutation, but from which it is distinguished by producing fruit which are larger and more highly colored than the fruit of the "Topcrest" peach tree and which are mature for harvesting and shipment approximately two and one-half weeks after the fruit of the "Topcrest" peach tree.

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 "Bev's Red" and, more particularly, to a peach tree which produces fruit which are mature for commercial harvesting and shipment approximately May 15 to May 18 in the southern San Joaquin Valley of California and which are large sized, highly colored and of good quality.

The development of new varieties of fruit trees is a continuing and necessarily painstaking process. The commercially significant attributes and general quality of tree fruit available on the market continues to improve as the result of the discovery and development of new varieties of fruit trees. As a consequence, varieties which were once considered superior may be surpassed in a very few years by new varieties with greater commercial appeal. Thus, in an effort to keep pace with competitors, many of those within the industry aggressively seek new varieties of superior character, particularly as to those criteria which the industry deems most important. Without such efforts, there is a risk of not remaining competitive in the marketplace.

However, the selection of superior fruit tree varieties from among a myriad of candidates requires patient observation over many years. A new variety which is a descendant of an existing, commercially successful variety may be an attractive candidate. Nonetheless, frequently such new varieties lack certain characteristics required for commercial success. It is rare to find such a new variety which exceeds the characteristics of an illustrious parent in a multiplicity of commercially significant criteria. The new variety of the present invention is believed to be such a descendant.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The variety of peach tree of the present invention was discovered in 1992 by the inventor in his orchard which is located near Arvin in the southern San Joaquin Valley of California. The invention discovered the new variety as a mutation of the "Topcrest" peach tree. The orchard was originally planted as "Fairlane" peach trees in 1987. These trees were grafted to "Topcrest" peach trees in 1988. The applicant asexually reproduced the new variety in February, 1993 by grafting scions taken from the sport on to a "Topcrest" peach tree and a "Queencrest" peach tree in the same orchard. The invention observed the asexually reproduced grafts of the new variety and the fruit produced thereby and found them in all respects to be identical to the parent.

SUMMARY OF THE NEW VARIETY

The "Bev's Red" peach tree is characterized as to novelty by producing large, semi-freestone fruit which are of very high coloration. The fruit of the new variety are ripe for commercial harvesting and shipment approximately May 15 to May 18 in the southern San Joaquin Valley of California, or about two and one-half weeks after the fruit of the "Topcrest" peach tree of which it is a mutation. The fruit of the new variety is further distinguishable from that of the "Topcrest" peach tree by being consistently larger in size and more highly colored, having a blush coloration varying from light to darker red extending over seventy-five percent (75%) to ninety percent (90%) of the surface area thereof.

Tendency to split.--No specific tendency to split has been observed.

Use: Fresh market.

Keeping quality: Good.

Although the new variety of peach tree possesses the described characteristics noted above as a result of the growing conditions prevailing near Arvin in the southern 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, pest control, seasonal climatic variation and the like are to be expected.

Claims

1. A new and distinct variety of peach tree substantially as illustrated and described and which is somewhat remotely similar to the "Topcrest" peach tree from which it was derived, but from which it is distinguished by producing larger, more highly colored fruit which are mature for commercial harvesting and shipment approximately May 15 to May 18 in the San Joaquin Valley of California, or about two and one-half weeks after the fruit of the "Topcrest" peach tree.
