A new table grape variety 'Zhongputao No.10'

'Zhongputao No. 10'is a new variety of early ripening grapes, which is bred through crossing between'Victoria'and'Muscat Hamburg'in 2004. In late July 2004, the hybrid seeds were cultured in vitro by embryo culture method. The hybrid seedlings were planted in vineyard of Zhengzhou Fruit Research Institute at early May. In 2007 the hybrid seedlings began to bear fruit. After several years of observation and identification, 2004-03-26 was selected as an excellent plant. After regional adaptability testing at different sites(including Luoyang city, Jiaozuo city, and Shangqiu city of Henan province), it was finally selected for its excellent quality. In 2018, it was put on records by the Henan Province Committee for Forest Variety Validation.'Zhongputao No.10'is diploid plant. The plant growth potential is medium. The young shoot is half opened, and the color is green, semi-upright.Young leaves have a purplish red color as the leaves grow, the leaves turn green. Villi in the lower surface of leaf is sparse. The shape of mature leaf is pentagonal with yellow-green color. Leaf margin is serrate with both sides convex and the petiole is u-shaped. The surface of mature branches has a red-brown skin and stripes, its tendrils are semicontinuous and medium length. The flower of this grape variety is bisexual, the first inflorescence is usually born in the third or fourth section of the branch. Each fruit contains 1-3 seeds, most of which are 1 seed, and the seed and pulp are easy to separate. The fruit cluster is conical shape with the average mass 490 grams. The berry is green yellow color when fully ripe,oval shape, and average weight is 8.5 g. The berries have thin pericarp. The flesh is crisp and sweet.The contents of soluble solids, total soluble sugar, total acid, tannin, vitamin C, amino acid was 17.9%,16.0%, 0.57%, 433 mg · kg-1, 5.41 mg · 100 g-1 and 5.09 g · kg-1, respectively. The sugar-acid ratio reached28∶1. The time from bud breaking to harvest is about 110 d, its time of bud-burst at the early of April,and flowering at the middle of May, fully mature date at mid-July in Zhengzhou area. The principle of“prevention is the main and comprehensive control”should be carried out in disease control, and attention should be paid to the control of green plant bug and thrips in germination period. When the rainy season comes, attention should be paid to the prevention and control of downy mildew. The second year of planting young trees can bear fruit, and the third year will reach the full fruit stage, the yield will be controlled at 20 t · hm-2. Vertical trellis systems and V-frame systems are used suitably in open field cultivation. the planting density was as follows: the space of plantation as 1 m×3 m. Available nitrogen fertilizer is applied before germination, nitrogen and phosphorus compound fertilizer is applied before flowering, and nitrogen-phosphorus-potassium fertilizer are applied at the stage of grape berry expansion.While applying fertilizer, it can be watered at the same time. This grape variety is suitable for short branch pruning in winter and winter pruning ends by the end of February the second year, no later than the first ten days of March at the latest.
