Peach tree

Abstract

A new and distinct variety of peach tree which is characterized by fruit which is clingstone in nature and which has a flesh which is bright yellow in color and which is ripe for commercial harvesting from July 27 to August 1 in Modesto, Calif.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peach tree denominated varietally as "Haig Arakelian, Sr." and more particularly to such a peach tree which bears a clingstone fruit which has a non-melting flesh texture, which is bright yellow in color and which is additionally characterized as to novelty by a date of ripening of approximately July 27 through August 1, in Modesto, Calif.

From an economic perspective, the relative dates that various varieties of peaches become ripe for harvesting is of extreme importance to the owners of orchards of stone fruits. It has long been recognized as desirable to provide a peach tree that bears fruit during a portion of the season later than other varieties of peach trees, which it most nearly resembles, whereby the fruit can be sent to market at a time when competition is at a minimum and the best price can be negotiated. It should be understood that an additional economic benefit is attached if the harvesting period of a particular orchard is spread over a longer period of time, because the capital expenditure required to harvest and transport produce from the orchards can be spread over an extended period resulting in overall lower costs of the final product and increasing uniformity of production throughout an entire season.

The new and distinct variety of peach tree is characterized as to novelty by producing a peach which matures for harvesting at mid-season; approximately July 27 through August 1 in Modesto, Calif., and in addition has demonstrated a greater fruit sizing potential than other varieties to which it is most closely similar.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The new and distinct variety of peach tree of the present invention is of unknown origin, and was discovered by the applicant in a cultivated area of his orchard which is located at the corner of Church and Garst Streets, Modesto, Calif. The new variety, which was first observed in July, 1979, during routine orchard operations, was asexually reproduced by taking budwood from the subject tree and thereafter budding it on Nemaguard peach rootstock. This procedure took place in May of 1984. The budded trees have been constantly observed by the applicant and it has been determined that the progeny produced possess the same distinctive characteristics as the parent tree.

Inasmuch as the prevent variety's precise origin is unknown, it was known by the applicant in the sense that he discovered the new variety of peach tree in a cultivated area owned by him, recognized its distinctive qualities, asexually reproduced the same, and tested the subject seedling at the designated orchard located at the corner of Church and Garst Streets, Modesto, Calif.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing is a color photograph of a characteristic twig bearing typical leaves which display both the dorsal and ventral coloration; four peaches showing their external colorations sufficiently matured for harvesting and shipment; a peach halved transversely of the suture plane to illustrate the flesh coloration; and a stone, all of the subject variety.

DETAILED DESCRIPTION

Referring more particularly to the pomological details of the new and distinct variety of peach tree the following has been observed under the ecological conditions prevailing in the orchard of the inventor in Modesto, Calif.

Although the new variety of peach tree prossesses the described characteristics as a result of the growing conditions prevailing in Modesto, Calif. in the north-central portion of the San Joaquin Valley, it is to be understood that variations of the usual magnitude and characteristics incident to growing conditions, fertilization, pruning and pest control are to be expected.
