Nectarine tree "Olympia"

Abstract

A new and distinct variety of nectarine tree denominated varietally as "Olympia" which is somewhat similar to the Red Jim Nectarine Tree (U.S. Plant Pat. No. 4,518) with which it is most closely related, but which is distinguished therefrom, and characterized as to novelty by producing fruit which is mature for commercial harvest approximately September 2 through September 23 at Fresno, Calif.; and which has fruit that has a bright red and glabrous skin; a firm flesh; and noteworthy storage characteristics.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of nectarine tree, designated varietally as "Olympia", and more particularly to such a nectarine tree which produces fruit which ripens for harvesting from September 2 to September 23, approximately seven days after the Red Jim Nectarine (U.S. Plant Pat. No. 4,518); and which is further distinguished as to novelty by producing fruit whose flesh is firm; the skin of which has a brilliant red and glossy color; and which further produces spherical fruit of substantially uniform size, fruit which exhibit excellent holding quality on the tree and noteworthy storage characteristics after harvest, particularly if under refrigeration.

In a continuing effort to upgrade the quality of his fruit, the applicant is constantly on the alert to locate any new varieties that may appear as chance seedlings in his orchard. In these labors the applicant, in 1981, discovered an open-pollinated seedling which originated from a Royal Giant Nectarine Tree (U.S. Plant Pat. No. 4,107), within the cultivated area of his commercial orchard located at 9284 South Rio Vista Avenue, Reedley, Calif., in the County of Fresno.

ORIGIN

The present variety of nectarine tree was an open-pollinated seedling originating from a Royal Giant Nectarine Tree (U.S. Plant Pat. No. 4,107) within the cultivated area of the commercial orchards under the ownership and control of the inventor at 9284 South Rio Vista Avenue, Reedley, Calif. The subject variety was observed, at that time, to have desirable characteristics and it was thereafter asexually reproduced by the inventor at the same orchard by a bud-graft technique from the original open-pollinated seedling to positions on a fruit bearing Royal Giant Nectarine Tree for the purposes of determining whether the fruit characteristics were true to the original seedling. This first asexual propagation, which occurred in 1981, was continually observed by the inventor, and it has been subsequently determined that the progeny produced possess the same distinctive characteristics as the original open-pollinated seedling.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is a color photograph of a characteristic twig bearing typical leaves, three nectarines showing their external colorations sufficiently mature for harvesting and shipment, a nectarine halved transversely of the suture plane to illustrate the flesh coloration, and a typical stone all of the subject variety.

DETAILED DESCRIPTION

Although the new variety of nectarine tree possesses the desired characteristics as a result of the growing conditions in Fresno County, Calif., in the central part of the San Joaquin Valley, it is to be understood that variations in the usual magnitude and characteristics incident to growing conditions, fertilization, pruning and pest control are to be expected.
