Apple tree named ‘LJ-1000’

Abstract

A new and distinctive variety of apple tree is described, and which is characterized as to novelty by producing an attractively colored apple which is mature for harvesting and shipment approximately September 16th under the ecological conditions prevailing in Central Washington State.

Description

Latin name of the genus and species of the plant claimed: Malus domestica Borkh.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of apple tree ‘Malus Domestica Borkh’, and which has been denominated varietally, hereinafter, as ‘LJ-1000’, and more particularly to an apple tree which bears an attractive highly colored fruit which is distinguished as to novelty by its firm texture, earlier coloring, and high sugar levels when compared to the closest known variety, and when grown under the ecological conditions prevailing near Quincy, Wash. in the central region of Washington State.

ORIGIN AND ASEXUAL REPRODUCTION

It has long been recognized that an important factor contributing to the success of any new variety of apple tree bearing fruit for the fresh market is its appearance, and respective harvesting date, in relative comparison to other varieties bearing similar fruit in the same season. Similarly, other significant factors affecting the commercial viability of any new strain of apple relates to its flavor, as reflected by its sugar content, as well as the storage characteristics of the fruit.

The new apple tree variety ‘LJ-1000’ is noteworthy in producing a fruit which is ripe for harvesting and shipment at approximately Sep. 16, 2009 under the ecological conditions prevailing near Quincy, Wash. Further, in contrast to the apple tree which it is most closely similar to, that being, the ‘Honeycrisp’ apple, U.S. Plant Pat. 7,197, the present tree is distinguished therefrom by developing earlier color which is overall more intense than the fruit produced by the ‘Honeycrisp’ apple tree (U.S. Plant Pat. 7,197) (See FIG. 4). Additionally, the new variety shows greatly enhanced storage characteristics in relative comparison to the fruit produced by the ‘Honeycrisp’ apple tree (U.S. Plant Pat. 7,197) when grown under similar ecological conditions.

The new variety of apple tree as described herein was discovered within the cultivated region of an apple orchard, owned by the inventor, and which is located near Quincy, Wash. in 2005. In this regard, the present variety was discovered following the grafting of ‘Honeycrisp’ apple tree (U.S. Plant Pat. No. 7,197) wood onto then existing Sansa apple trees (U.S. Plant Pat. No. 6,519) during the 2003 growing season. This grafting took place within the same orchard. During routine orchard operation in 2005, it was discovered that one of these grafted trees (the present variety) colored earlier and to a greater extent than the adjacent ‘Honeycrisp’ apple tree (U.S. Plant Pat. No. 7,197). In 2006, scion wood was removed from this earlier discovered tree, and then grafted onto other Sansa apple trees (U.S. Plant Pat. No. 6,519) growing in this same orchard. These second generation test trees have been continually observed until most recently. Also, during this time period, the inventor diligently compared and contrasted the first asexually reproduced trees, and the fruit produced thereby with that of the originally discovered tree. In all respects, they appeared to be identical. None of the foregoing test trees have ever been sold or offered for sale to the public while undergoing this comparative testing and evaluation.

It has been confirmed through all the aforementioned observations that the earlier asexual reproductions, as noted above, resulted in apple trees which produce fruit which possess the same distinctive characteristics as the original newly discovered tree.

SUMMARY OF THE VARIETY

The ‘LJ-1000’ apple tree is characterized principally as to novelty by producing an attractively colored fruit which is ripe for harvesting and shipping approximately September 16 under the ecological conditions prevailing in central Washington State. In contrast to the variety which it is most closely similar to, that being, the ‘Honeycrisp’ (U.S. Plant Pat. No. 7,197), which matures at about the same time at this geographical location, it is distinguishable therefrom by being more highly colored at harvest and having improved storage characteristics. In addition to the foregoing, the ‘LJ-1000’ apple tree has noticeably elevated sugar levels which clearly distinguishes it from other varieties which it is most closely similar to such as the ‘Honeycrisp’ apple tree (U.S. Plant Pat. No. 7,197). These and other characteristics make the present apple tree variety highly desirable as a producer of fresh fruit for both local and long distance markets.
