Abstract

A new and distinct variety of plum tree which has been denominated varietally as `Sir George` which is distinguished by producing uniformly large fruit of a semi-globular form, which has a distinct flavor and which is mature for harvesting and shipment approximately the fourth week of July.

Description

BACKGROUND OF NEW VARIETY
The present invention relates to a new and novel variety of plum tree (Prunus salicina), which will hereinafter be denominated varietally as the `Sir George` plum tree, and more particularly to a plum tree which produces a firm, uniformly large fruit having a distinct flavor, and which is mature for commercially harvesting and shipment approximately the last week of July under the ecological conditions prevailing in the San Joaquin Valley of Central California.
The commercial appeal of a given variety of tree fruit may be based upon one or more attributes. Characteristically, commercially successful tree fruit possess noteworthy attributes in several significant categories: flavor, keeping quality, size, shape and skin coloration. The relative importance of these categories are readily evident. However, in reality, the very nature of the evaluation in several key areas renders an overall evaluation of a selected variety, in most cases, somewhat subjective to some degree. Thus, for example, the appeal of the flavor of a given tree fruit may largely be dependent upon personal preferences.
As a consequence, distinctive attributes in the more objective categories such as size, shape and skin coloration are often very important to the commercial success of tree fruit. In this regard, typically the larger the size of the fruit, the greater the commercial appeal. The same may be said of tree fruit having a uniformly distinctive shape and an intense skin coloration. As a general matter, it is unusual to find a variety of tree fruit possessing exemplary attributes in a number of these more objective categories.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The present variety of the plum `Sir George` was discovered by the inventor in 1989. This new variety was discovered within the cultivated area of his orchard, which is located near Fowler, Calif. The new variety was selected from 112 seedlings found in his orchard, and which was originally planted with the varieties `Challenger` (unpatented) and `Showtime`, U.S. Plant Pat. No. 8,037. An examination of this new variety reveals that this tree expresses some of the traits of each of these two trees (`Challenger` and `Showtime`) and has some expressions which are intermediate other traits of both trees. Consequently, it is believed that this tree is probably an F1 hybrid of the varieties `Challenger` and `Showtime`. The new variety was asexually reproduced at the inventor's direction in June, 1994 by budding the new variety onto `Nemaguard` rootstock which was growing along Springfield Avenue in Fresno County, Calif. in June of the same year. The resulting asexually reproduced trees were later planted in an orchard located on the inventor's property in Fowler, Calif. These trees have been observed by the inventor since that time and it has been confirmed that the distinctive characteristics of the original tree were expressed in the asexually reproduced trees.
BRIEF DESCRIPTION OF THE DRAWING
The drawing is a color photograph showing four mature fruit of the new variety of plum tree including a first one shown in a top view; a second one shown in side view displaying the suture thereof; a third one showing the shape of the apex of the fruit; a fourth one showing a section of the fruit cut generally along the suture and laid open to display the stone well; a fifth view showing the stone itself; and a portion of the foliage attached to a young terminal twig with several detached leaves showing both the dorsal and ventral coloration thereof.
