Beauty finger is a diploid Eurasian species bred in 1984 by Japan's Uygara Grape Research Institute with Unikun × Baradei No. 2 cross. introduced in the winter of 1996, the fruit in 1998. Performance is excellent. The fruit is very good. Fruit grains elongated, apex purple-red, bright, the base is slightly light, just like a beautiful woman's fingers dyed red nail polish, beautiful appearance.

Morphological characteristics

Beauty Finger tender tips yellow-green, sunny side purple-red, no downy, young leaves bright, yellow-green, slightly reddish-purple, glossy; the variety of strong growth, branches erect, robust, green branches sunny side purple-red, mature branches brownish-grayish-white, longer internodes, part of the tendrils growing between the two buds, adult leaf blade medium-large, dark green. Pale, 5-lobed, upper lobe varying in depth, abaxial surface of leaf not velutinous, leaf blade smoother, leaf margin serrations obtuse, petiole reddish-purple.

Growing environment

Beauty finger grapes grow like warm and cool climate, cultivated in Jiangnan region of China can be through the normal dormancy, strong budding force, vigorous growth, fruit clusters are very large, fruiting rate is high, good color, but the branches of the late maturity of the obvious, susceptible to white rot disease, sunburn serious. In the case of improper cultivation and management, this variety is really not easy to bear fruit, and the yield is extremely unstable.? [2]? Strong resistance, poor disease resistance, weak resistance to downy mildew, black pox, gray mold, powdery mildew, moderate insect resistance. Susceptible to disease, this is the Eurasian species of grape varieties **** nature, beauty finger is no exception.

Strong plant growth potential, high budding rate, high percentage of fruiting branches, the average number of fruit spikes per fruiting branch 1.6 spikes, medium fruiting rate; secondary buds sprouting force is particularly strong, the knotting strength of the weak; hidden buds sprouting force of the medium, the knotting strength of the medium; the secondary tip of the fast-growing, the knotting strength of the weaker; fruit clusters and the consistency of fruit maturity is better, berry maturity after the fall of grains is lighter; early yield is good, yielding sex is medium, the second year of the establishment of the park Most of the young trees hang fruits, the third year output can reach 7500~9750Kg/hm2, the fourth year output can reach 13500~16500Kg/hm2, and from the fifth year onwards the output can reach 18750~22500Kg/hm2.?

Fruit Economic Characteristics

Spike long conical, medium-large, no secondary spikes, out of the fruit is generally spike weight 300 ~ 400g, productive period is generally in 450 ~ 600g, the maximum 1750g, the kernel is large, elongated type, the average weight of the single grain is 10 ~ 12g, the maximum grain weight of 19.2g. The kernel is larger, the longitudinal diameter of about 2.6 ~ 3.3cm, the maximum longitudinal diameter of up to 5.5cm, longitudinal and transverse ratio of 3:1, the apex of the fruit is bright red, lubricated and bright, the base is slightly lighter in color, the peel is difficult to separate the pulp, the skin is thin and tough, it is not easy to crack the fruit, not threshing, the flesh is tight and crisp translucent, can be sliced, sweet and crisp flavor, low acid content, fragrance, soluble solids up to 16% ~ 19%, the fruit is resistant to storage.
