Description

Latin name: Malus domestica.

Varietal denomination: ‘HS RED’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new, novel, and distinct variety of apple tree which is denominated varietally, as ‘HS RED’, hereinafter.

ORIGIN

The present variety of apple tree was discovered in June 1998 as a chance limb sport then growing on an ‘Oregon Spur II’ apple tree (U.S. Plant Pat. No. 4,839). This ‘Oregon Spur II’ apple tree was growing on seedling rootstock, within the cultivated area of a commercial orchard which is located at 80 McNeil Canyon Road, Orondo, Wash. The ‘Oregon Spur II’ tree upon which the limb sport was discovered was first planted during the 1984 growing season. After discovery, bud wood from the promising limb sport was removed, and then T-budded into a two year old ‘Oregon spur II’ apple tree, which was then growing on M106 rootstock (unpatented) during August 1998. This first asexual reproduction of the variety occurred at a commercial orchard, which is located at 452 Godfrey Springs Lane, Chelan County, Chelan, Wash. The aforementioned orchard is located in USDA Zone 7A. Fruit generated from this first asexually reproduced tree was identical in appearance and development as that expressed by the originally discovered sport limb. Further, additional asexually reproduced trees were propagated from the wood gathered from this first asexually reproduced tree and which were later grafted onto M106 rootstock. The subsequently planted, and asexually reproduced trees were then grown in the same orchard, which is located in Chelan, Wash. This propagation took place during the 2006 growing season. Fruit produced from the subsequent generations of trees have been found to be identical to that of the original discovered sport limb.

SUMMARY OF THE NEW VARIETY

‘HS RED’ appears to be a whole tree bud mutation of the ‘Oregon Spur II’ Red Delicious apple tree [U.S. Plant Pat. No. 4,839]. However, the newly discovered tree differs from its parent by its fruit characteristics, and further in its spur development, and blooming dates. ‘HS RED’ exhibits a more intense spur development resulting in a more compact tree form than that which is typically seen with the ‘Oregon Spur II’ apple tree when it is grown on M106 rootstock [unpatented]. More specifically, the fruit of the ‘HS RED’ exhibits a conical fruit form, which is so characteristic of the fruit produced by the ‘Oregon Spur II’ apple tree, but its skin appearance, flesh color, flesh vascular bundle color, and harvest fruit characteristics, as set forth below, are quite different. In particular, the skin color development of the ‘HS RED’ is fully and uniformly developed as a wash-type color three months prior to the harvest, in relative comparison to the fruit produced by the ‘Oregon Spur II’ apple tree, which is just beginning to develop its stripe colored pattern at that time. In regards to the new variety, it has been noted that as the skin color is developing, so is the corresponding flesh color developing to its final harvest color. In contrast, the fruit produced by the ‘Oregon Spur II’ apple tree does not develop its final flesh color until it is very close to full harvest maturity. It should also be noted that all the vascular bundles surrounding the core area of the fruit are colored in the ‘HS RED’ apple tree, and appear as hues of its skin color. In contrast, the bundles as seen in the fruit produced by the ‘Oregon Spur II’ fruit are not so colored. Moreover, the sugars; acid levels; pH; brix; and fruit pressures are different in the new variety's fruit at full harvest maturity when compared with the closest known variety. In particular, the fruit of the ‘HS RED’ apple tree displays a higher pressure; a higher brix; a higher acid level; and lower pH than that which is typically seen in the fruit produced by the ‘Oregon Spur II’ apple tree, when grown under similar conditions. It should be noted that these differences are not typically observed following four months in common storage at the same geographical location. The date of full bloom of the ‘HS RED’ apple tree is noted to be three days in advance of the ‘Oregon Spur II’ apple tree when grown at the same geographical location.
