[Breeder] Zeng Jianming; Zhang Zhifang; Wang Lu; Hao Xinwang; Wang Xinchao; Li Xiaoman; Guo Lina. [Variety Number]: Non-major crop variety registration number: GPD Tea Tree (2023)330056. [Variety origin]: Selected by Tea Research Institute of the Chinese Academy of Agricultural Sciences from the natural hybrid progeny of 'China Tea 108' as a single plant. [Characteristics]: Shrub type, early-blooming species, erect posture, medium leaf type, leaf blade length 8.1 cm, width 3.9 cm, leaf blade medium oval, leaf blade attachment state upward. In Shengzhou area, the spring tea bud one leaf period is in the middle and late March, the new buds are yellowish green, with dense velvet hairs, the length of one bud and three leaves is 7.0 centimeters, and the weight of one hundred buds is 43.7 grams. Spring tea bud two leaves biochemical samples containing tea polyphenols 18.3%, amino acids 4.4%, caffeine 3.6%, water leachate 48.4%. Suitable for green tea. Baked green tea, the appearance of tight, slightly curled, hair, more tender green, soup color is more tender green and bright, the aroma is more high and fresh, floral aroma is obvious, there is a tender flavor, taste is more sweet and fresh, slightly astringent. The first growth cycle of the annual mu yield of one bud and two leaves of 1458 kg of fresh leaves, 31% more than the control 'Fuding large white tea'; the second growth cycle of the annual mu yield of 1307 kg, 8% more than the control 'Fuding large white tea'. Highly susceptible to tea small green leafhopper, susceptible to tea anthracnose, resistant to cold and drought. The variety of selenium polymerization ability is strong, under the same conditions, for three consecutive years, the average content of smashing in the tea leaves of one bud and two leaves is 27% higher than the control group (the average value of 20 breeding varieties). [Suitable planting areas and cultivation techniques] It is suitable for planting in the Jiangnan Ecological Zone, Zhejiang Shengzhou, in the fall or spring when rainfall is more abundant. It is suitable to use single row double plant or double row double plant planting, timely prevention and control of tea leafhopper, tea anthracnose, especially early species pay attention to prevent the “spring cold”.
