Plum tree, "Majestic M"

Abstract

A new and distinct variety of Plum Tree which is characterized as to novelty by a date of maturity for harvest and shipment during the second or third week of October under the ecological conditions prevailing near Orosi, Calif.; the date of harvesting being approximately two or three weeks later than the Angeleno Plum Tree (U.S. Plant Pat. No. 2,747) with which it is most closely similar in its overall physical characteristics, and approximately ten weeks later than the Friar Plum Tree from which it was discovered as a chance sport, and which is further distinguished as to novelty by producing uniformly shaped fruit which have exceptional storage and shipping characteristics.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of Plum Tree, denominated varietally as "Majestic M" and more particularly to such a plum tree which bears a full freestone fruit which has a flesh which has a crisp texture and a yellowish-brown color and which is principally characterized as to novelty by a date of ripening of approximately October 15 through October 20, in the San Joaquin Valley of Central California.

From an economic standpoint, the relative dates of ripening of various varieties of plums is obviously of extreme importance. It has long been recognized as desirable to provide a plum tree that bears fruit later in the season than other varieties of plum trees which it most nearly resembles whereby the fruit can be sent to market at a time when competition is at a minimum. In addition, if the harvesting periods of various plums can be effectively spread over a longer period of time, considerable savings and increased efficiency can be attained because the capitol expenditures required to harvest and transport such plums can be spread over a longer period of time resulting in lower costs of the final product and increasing uniformity and production.

The new and distinct variety of Plum Tree, "Majestic M" is further characterized as to novelty by producing fruit which are somewhat remotely similar in their physical characteristics to the plum produced by the Angeleno Plum Tree, U.S. Plant Pat. No. 2,747, said Angeleno Plum Tree maturing for harvesting and shipment in middle or later September in the San Joaquin Valley of Central California and in addition by producing fruit which have noteworthy storage and handling characteristics.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The new and distinct variety of Plum Tree hereof was discovered by the Applicant, as a chance sport, during routine orchard operations in 1984. The sport, which was discovered in the cultivated area of an orchard owned by the Applicant and which is located between Road 164 and Avenue 416, approximately five miles east of Orosi, Calif., in the County of Tulare, was found growing on what is believed to be a Friar Plum Tree (believed unpatented), the tree of origin having been damaged on an earlier occasion by mechanical harvesting equipment. Upon discovering the chance sport the inventor marked the tree and thereafter continuously observed it for purposes of determining its characteristics. It was subsequently determined that the sport produced fruit which matured for harvesting and shipment at a date noticeably later than that of the surrounding Friar Plum Trees, which are ripe for commercial harvesting and shipment approximately the end of July in the San Joaquin Valley of Central California. The Applicant subsequently removed wood from the chance sport, and grafted it into Nemaguard rootstock for purposes of further evaluation. This first asexual reproduction occurred in the Fall of 1984. A first evaluation of the fruit produced by the chance sport was accomplished in 1984. It was during this first evaluation that the Applicant discovered, upon a comparison of the subject plant with other known varieties of plum trees, that the instant variety "Majestic M" was indeed a new and distinct variety of plum tree. The Applicant has continually observed the subject variety and it has been determined that the asexually reproduced progeny exhibit the same distinctive characteristics as the original sport.

The "Majestic M" Plum Tree of the present invention is noteworthy in ripening approximately ten weeks later than the Friar Plum Tree (believed unpatented), and from which it was derived as a chance sport, and approximately two or three weeks later than the Angeleno Plum Tree (U.S. Plant Pat. No. 2,747) with which it is most closely similar with respect to its physical characteristics, but which is distinguished therefrom by producing fruit which have a greatly improved fruit quality and which further have a good flavor and have a crisp and juicy fruit texture.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing is a color photograph of three mature fruit of the subject variety, two of which display their external coloration sufficiently mature for harvesting and shipment, and one of which has been divided in the axial plane to display the flesh and stone coloration, together with a pair of leaves which display the coloration of their upper and lower surfaces and a representative sample of bark all of the subject variety.
