ABSTRACT:
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 ‘Weolme’, which has been patented in Korea (Patent No. 52872) 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, sweeter than the fruit of the parent tree, ‘Weolme’, 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 round 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. We are 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 ‘Weolme’ variety, which had been planted on our farm in Seomyun, Yunkikun, Chungnam, Korea. The seedling was discovered near a specimen of the noted apparent seed parent, which is an early season variety and which normally ripens between July 20 to August 5, which is 5 days earlier than ‘Weolme’. Our attention was drawn to this tree when we noticed that the skin of the fruit was very smooth; producing regular form and sweeter by about 0.5 to 1°(Bx) than the parent ‘Weolme’ variety on the wood. ‘Weolme’ is influenced by temperature and rain at the time of pollination, thereby resulting in production of irregular form of the fruit, whereas the present ‘Sprinter’ is not affected by weather conditions such as temperature, rain etc. Based on these observations, we 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 or grafting in our 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 propagation.
SUMMARY OF THE VARIETY
The present new and distinct variety of peach tree has been denominated ‘Sprinter’, and the height of the fully grown tree about 3 to 3.5 meters, which is almost same with that of the tree, ‘Yumyeong’. The diameter of the new tree is about 6 to 7 meters. This tree grows vigorously on standard peach rootstock, with a half open shape and is a regular and productive bearer of extra large, skin with pink overspread with light yellow, 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, approximately 5 days after ‘Weolme’, and 30 days before ‘Yumyeong’, which are established commercial varieties in Korea.
