| Claim: |
Having thus described and illustrated my new variety of apple tree, what I claim is new, and desire to secure by Plant Letters Patent is:
1. A new and distinct variety of apple tree Malus pumilaMill substantially as illustrated, and described, and which is characterized principally as to novelty by bearing an attractively colored apple which is mature for harvesting and shipment about August 30.sup.th under the ecological conditions prevailingnear Ephrata, Wash. |
| Description: |
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of apple tree Malus pumila Mill and which has been denominated varietally as `PB-148`; and more specifically to an apple tree which is principally characterized as to novelty by bearingan attractive, highly colored apple having a good flavor, and shelf life and which is ripe for harvesting and shipment under the prevailing ecological conditions existing in the Columbia Basin area of central Washington State on and about August30.sup.th.
The present variety of apple tree Malus pumila Mill resulted from a cross pollination which was made by me of a `Gala` apple tree (U.S. Plant Pat. No. 3,637) with a New Zealand Red Crab Apple Tree, which is denominated varietally as `Jack Humm`and which is unpatented. The variety `Jack Humm` was derived from a cross of the unpatented Crab Apple Tree `Gorgeous` and the unpatented variety `John Downie.` The variety `John Downie` is known for producing fruit which are excellent for jelly making. This cross-pollination occurred within the cultivated area of my orchard which is located in Central Otago, New Zealand during the 1987 growing season. After observing the characteristics of this new tree for a number of years, budwood from the new`PB-148` apple tree, then growing in Central Otago, New Zealand, was sent to the quarantine facility which is located at Prosser, Wash. in August of 2000. Following the treatment of the budwood by the Prosser facility, virus-free budwood was thenreleased from the facility in August, 2001. Thereafter, this novel tree was asexually reproduced using this same budwood by grafting this same budwood into test trees which were then growing on `M26` rootstock (unpatented) at a commercial test orchardwhich was located near Ephrata, Wash. Thereafter, the second generation grafted trees, which were growing in Ephrata, Wash. were observed for three cropping seasons and the fruit produced from same was repeatedly compared and contrasted with the fruitearlier produced on the original mother tree which was still growing in my orchard which is located in Central Otago, New Zealand. These subsequent botanical and pomological comparisons of the fruit produced by the second generation trees with that ofthe original mother tree revealed that the second generation grafted trees produced fruit, and had other botanical characteristics which appeared to be identical to that displayed by the original mother tree.
SUMMARY OF THE NEW VARIETY
The `PB-148` apple tree is characterized principally as to novelty by producing an attractive, highly colored fruit which is ripe for harvesting and shipment about August 30.sup.th under the ecological conditions prevailing in the Columbia Basinarea of central Washington State. The present variety is easily distinguishable from the fruit produced by `Gala` apple trees (U.S. Plant Pat. No. 3,637) in view of its attractively colored fruit. In relative comparison to the `Gala` apple treesgrown in the same geographical location, the average harvesting date for the most common `Gala` cultivars grown in the same geographical is about the same. However, the shape of the new variety of apple is considered round in contrast to the applesproduced by the `Gala` apple tree which appears more conically shaped. In relative comparison to the New Zealand Red Crab Apple Tree `Jack Humm` which was crossed with a `Gala` apple tree in order to produce the mother three `PB-148`, the presentvariety is clearly distinguishable by producing fruit which has a larger size and a noteworthy color. In this regard, the `Jack Humm` Crab Apple Tree typically produces clusters of oblong fruit having a bright crimson-red skin which has a yellow-orangeunderside. The fruit of the `Jack Humm` typically has a length of about 40 mm, and further persists on the tree long after the leaves have left the tree and often into the winter.
