Description

BACKGROUND OF VARIETY
In the country of origin, Republic of Korea, the tree of this disclosure is believed to have been derived from the Korean commercial variety `Yumyeong`, and within the subspecies dianthiflora (Dipp.); and, originated in Seomyun, Yunkikun, Chungnam, Republic of Korea. The appropriate botanical classification for this tree is believed to be Prunus persica. This subject tree is believed to be exceptional in a number of characteristics and will offer a further option to commercial growers of stone fruits in terms of fruit having large to very large size, firm flesh, clingstone, sweet, attractively colored fruit which has a comparatively high capacity to withstand handling, shipping and storage. Having the additional desirable fruit characteristics of heavy production of fruit with an attractive ovate shape and pleasant, sweet taste, and which is harvested earlier than normal harvest for fruit of extra large size, this tree promises to be a valuable new variety to industry and commerce which has value as a dessert variety but which may also be used as a canner. This tree further has the advantage of being mid to late-season in blooming so that it is less susceptible to late frosts than other locally adapted tree varieties. I am not aware of varieties which offer a similar or comparable combination of characteristics.
ORIGIN OF THE VARIETY
The new tree was selected from among several thousand seedlings from the `Yumyeong` variety, which had been planted on my farm in Seomyun, Yunkikun, Chungnam, Korea. The seedling was discovered near a specimen of the noted apparent seed parent, which is a late season variety and which normally ripens between August 20 and September 10. My attention was drawn to this tree when I noticed that it was unusually precocious; producing two to three times more flowers than the parent `Yumyeong` variety on blooming wood, and by having flowers of a much brighter color than the parent variety. With the recognition of these different characteristics, I allowed the tree to remain for further observation. Upon development and ripening of the fruit, it became clear to me that this tree showed promise due to its production of very high quality fruit of large to extra large size and unusual attractiveness. Based on these observations, I selected the variety for asexual reproduction and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction of the new and distinct variety was performed by budding in my orchard located in Seomyun Yunkikun, Chungnam, Korea and shows that all characteristics run true to the original tree and are established and transmitted through succeeding propagations.
SUMMARY OF THE VARIETY
The present new and distinct variety of peach tree has been denominated `Baekyakdo`, and the height of the fully grown tree is about 3 meters, which is about 50 cm smaller than that of the tree, Yumyeong, and the diameter of the tree is about 6 to 7 meters. The instant cultivar exhibits vigorous half open growth and is a regular and productive bearer of extra large, white skin, white flesh, clingstone fruit with a mild, sweet, subacidic flavor with excellent eating and stock quality. The fruit is further characterized by having very firm flesh, the ability to hang on the tree 10 to 17 days after maturity (shipping ripe), having good handling and shipping quality, a white skin ground color and ripening in the middle maturity season, approximately 10 days after `Changbang joseng`, 20 days before Yumyeong, which are established commercial varieties in Korea.
DESCRIPTION OF THE PHOTOGRAPHS
FIG. 1 shows typical specimens of the fruit of the new and distinct peach variety shortly after being picked (firm ripe); illustrating the exterior of the fruit, a fruit divided in its suture plane to reveal flesh coloration, pit cavity, and a stone remaining in place.
FIG. 2 depicts a flower of the peach tree `Baekyakdo`.
FIG. 3 depicts the blossoms of `Yumyeong` (unpatented), `Woulme` (unpatented), `Baekyakdo`, `Changbang joseng` (unpatented), and `Wangdo` (the subject of copending U.S. Plant Patent application Ser. No. 08/862,644), from left to right.
FIG. 4. depicts typical leaves from `Wangdo` (above) and `Woulme` (below). The leaf shape of `Baekyakdo` is the same as that of `Woulme`.
The colors depicted are as true as is reasonably possible to attain in color reproductions of this type.
DESCRIPTION OF THE VARIETY
The following is a detailed botanical description of the new and distinct variety of peach tree, its flowers, fruit and foliage as based on observations of the specimen grown in my orchard located Seomyun Yunkikun Chungnam, Korea, with color terminology (except those in common terms) in accordance with Pantone® Professional Color System Selector (Pantone, Inc., 1984, 1990).
