Novel grape species

Abstract

The invention provides a cultivation method for 'Jinying' novel grape species. Hard branches of dozens of Kyoho grapes are selected as scions; tens of summer black grape trees are selected as stock and pollinizers; in May, the hard branches of the Kyoho grapes and the summer black grape trees are grafted, after survival, only one Kyoho grafting branch can be reserved on each tree, and the other branches are sheared off; in the current year, after to-be-grafted Kyoho grapes bloom, the Kyoho grapes are mated with blooming summer black grapes, and isolation pollination is performed; in the current year, the grafted Kyoho grapes on the summer black grape trees are fruited, seeds are taken and embedded into sandy soil, in the next March, seedling growing is performed, and in the current July, green branch transplanting is performed. The average fruit weight of the species is about 12 grams, and the sugar content is about 16-18%. The mature period is about 20 days ahead of the schedule of the Kyoho grapes and about 10 days later than the summer black grapes, and the problems that the Kyoho grapes are seriously different in size and hard in fruit bearing in the flowering phase are effectively solved. The species has the only defect that the species has no immunity to gray mold and the gray mold needs to be prevented one more time compared with other species.
