[Breeder] Yang Yajun; Chen Ming; Wang Xinchao; Xi Yongzhao; Yu Fulian; Ye Wenguo; Jin Xin; Chen Jun; Xu Lianming; Bai Kunyuan. [Variety Number] Non-major crop variety registration number: GPD Tea Tree (2019)330033. former Zhejiang Forestry Variety Validation Committee forest tree variety recognition number: Zhe R-SV-CS-008-2013, Zhe S-SV-CS-005-2016. [Variety Source] Tea Research Institute of the Chinese Academy of Agricultural Sciences, etc. Selected and bred from a single plant of the local variety of Tiantai. [Characteristics] Shrub type, medium (late) growing species, upright posture, medium leaf type, leaf blade length 6.1 cm, width 3.0 cm, leaf blade medium oval, leaf blade attachment status horizontal or slightly upward. In Hangzhou area spring tea bud one leaf period in early April, the new buds and leaves goose-yellow, less velvet, a bud three leaves 4.4 cm long. The biochemical sample of spring tea bud and two leaves contains tea polyphenol (14.2±0.5)%, amino acid (7.3±0.4)%, caffeine (3.1±0.06)%, water leachate (43.5±2.4)%. Suitable for making green tea. It is suitable for making baked green tea, with the appearance of tender green and golden yellow, the soup colour of tender green and clear yellow, the aroma of tender fragrance, and the taste of fresh and mellow. The first growth cycle spring mu yield of one bud and two leaves 39 kg of fresh leaves, than the control ‘Huangjinya’ 21% increase in yield; the second growth cycle spring mu yield 54 kg, than the control ‘Huangjinya’ 39% increase in yield. More resistant to insects, susceptible to tea anthracnose, more resistant to cold, drought, resistant to Shang temperature. [Suitable for planting areas and cultivation technology points] Suitable for planting in Jiangnan and Jiangbei tea areas where the annual active cumulative temperature is greater than 3200C˚ in Zhejiang, Sichuan, Guizhou, Hunan in autumn or spring when rainfall is more abundant. Strong uprightness, need to appropriately reduce row spacing and increase planting density. Before the young stage is put into production, it can be shaded appropriately to improve the survival rate and growth potential, but after it is put into production, it should not be shaded, otherwise it will affect the degree of yellowing. Planting in areas where temperatures rise quickly in the spring may affect the degree of yellowing of the new shoots.
