[Breeder] Guangxi Zhuang Autonomous Region Tea Scientific Research Institute; Han Zhifu; Qin Xiuju. [Variety number] Non-major crop variety registration number: GPD Tea Tree (2023)450065. former National Crop Variety Validation Committee Validation number: GS13002-1994. [Variety origin] Guangxi Zhuang Autonomous Region Tea Leaf Scientific Research Institute selected from a single strain of 'Wantian Daye' from Lingui, Guangxi. [Characteristics] Small tree type, large-leaved, late-blooming variety. The tree posture is open, the growth potential is medium, the branching part is medium, the branching density is medium. Leaf blade upward bearing, medium oval, 13.7 cm long, 5.0 cm wide, leaf color yellow-green, apex obtuse. The exploitation period in Guilin is generally in the middle and end of March, and the full bloom period of one bud and two leaves is generally in the end of March; the germination density is medium, with less velvet; the length of one bud and three leaves is 7.5 centimeters, and the weight of one bud and three leaves in one hundred buds is 120.0 grams. The blooming period is from late October to late November every year. The biochemical sample of one bud and two leaves in spring is 24.0% of tea polyphenol, 3.0% of amino acid, 4.6% of caffeine and 48.0% of water leachate. Suitable for green tea, black tea and black tea. Make green tea, aroma tender, taste mellow, soup color light yellow bright; make black tea, soup color red, aroma sweet flower, taste strong flower; make six fort tea, soup color red, aroma aged, taste mellow and smooth. The first growth cycle mu yield of one bud and two leaves of 353 kg of fresh leaves, 27% less than the control 'Fuding Dabaicha'; the second growth cycle mu yield of 626 kg, 14% less than the control 'Fuding Dabaicha'. It is resistant to tea anthracnose, tea leafhopper, cold and drought resistance. [Suitable for planting area and cultivation technology points] Suitable for planting in Guangdong, Guangxi, Fujian winter and spring time with sufficient rainfall. Select deep soil, fertile flat or gently sloping land; appropriate use of double rows of double plant strip planting, mu with 6,000 seedlings; the first stereotypes pruning height of 15 cm, the use of section cut or the use of bending branches to promote branching cultivation canopy, in order to achieve early closure of the garden. The yield of this variety is medium, the germination period is late, it is suitable for planting with early varieties.
