Abstract

A new and distinct variety of Plum Tree which is characterized as to novelty by a date of harvesting and shipment approximately May 27 through June 3 under the ecological conditions prevailing at Fresno, Calif. in the San Joaquin Valley of central California.

Description

BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of Plum Tree which has been denominated varietally as "Jake's Best" and more particularly to such a plum tree which bears fruit which are somewhat closely similarly in their overall physical characteristics to the "Wuhl" Plum Tree (U.S. Plant Pat. No. 5,585) but which is distinguished therefrom and characterized principally as to novelty by producing fruit which are ripe for commercial harvesting and shipment approximately two or three weeks earlier than the fruit produced by the Wuhl Plum Tree and which further produces fruit that are semi-freestone by nature in contrast to the Wuhl Plum Tree which produces a clingstone fruit.
It has long been known that the marketability of plums can be influenced to some degree by numerous factors including its date of harvesting and shipment as well as its external appearance. The Jake's Best Plum Tree is noteworthy in producing an attractively colored, early season plum which is ripe for commercial harvesting and shipment from approximately the last week of May through June 3 in Fresno, Calif. and which has a commercially aesthetic appeal such as that presented by the Wuhl Plum Tree (U.S. Plant Pat. No. 5,585). The fruit produced by the subject variety is noteworthy in that it is somewhat similar in its overall physical characteristics to the fruit produced by the Wuhl Plum Tree but is distinguishable by being ripe for commercial harvesting and shipment approximately two weeks earlier than the Wuhl Plum Tree and is semi-freestone by nature.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The present variety of plum tree was discovered as an open pollinated seedling of unknown parentage growing within the cultivated area of Nursery No. 1, on applicant's Ranch No. 1, which is located at the corner of Kings Canyon and Fowler Avenues in Fresno, Fresno County, Calif. in 1980. The inventor, at that time, noted the novel characteristics of the instant variety of plum tree and marked the chance seedling for subsequent observation.
The first asexual reproduction of the present variety of plum tree occurred in 1981 when the inventor removed buds from the chance seedling and budded them into test trees which were then growing on the applicant's Ranch No. 1 located in Fresno, Calif. The test trees have been continually observed by the inventor and it has subsequently been determined that the budded test trees produce progeny which have identical characteristics to that observed in the original chance open pollinated seedling.
SUMMARY OF THE NEW VARIETY
The Jake's Best Plum Tree is characterized principally as to novelty by producing a good quality, early season plum. The present variety of plum tree bears a plum which is ripe for harvesting and shipment approximately two weeks earlier than the Wulh Plum Tree (U.S. Plant Pat. No. 5,585) with which it is most closely similar in its external appearance but which is distinguished therefrom and characterized principally as to novelty by bearing semi-freestone fruit which are somewhat smaller than that produced by the Wuhl Plum Tree.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawing is a color photograph of a characteristic twig bearing typical leaves, several mature fruit showing their external coloration sufficiently matured for harvesting and shipment, two fruit of the subject variety dissected in the axial plane to illustrate the flesh characteristics thereof and several stones, all of the subject variety.
DETAILED DESCRIPTION
Referring more specifically to the pomological details of this new and distinct variety of plum tree, the following has been observed under the ecological conditions prevailing at the orchard of the inventor which is located in Fresno, Calif.
