[Breeder] Wang Xiaoping; Wang Yun; Yang Xuemei; Li Chunhua; Xiong Yuanyuan; Ma Weiwei; Wen Weiqi; Guo Lei; Zhang Hall; Liu Xiao; Zhang Juan; Gao Xianrong; Tang Xiaobo; Liu Fei. [Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2022)510042. [Variety Source] Selected from 'Sichuan Medium and Small Leafed Species' monoculture by Sichuan Mingshan Tea Tree Seed Breeding Farm and others. [Characteristics and properties] Small tree type, medium leaf type, early growing species. The tree posture is semi-open, the growth potential is strong, the branching part is low, and the branching density is dense. Leaf blade upwards, leaf shape narrow elliptic, leaf length 10.3 cm, width 4.4 cm; leaf color medium green; leaf apex shape obtuse, the upper surface of the bulge strong, leaf edge undulate strong, the edge of the silver tooth in the leaf base cuneate. The exploitation period is generally in early March, and the blooming period of one bud and two leaves is generally in late March; the germination density is high, with much velvet; the length of one bud and three leaves is 7.6 centimeters, and the weight of one hundred buds is 34.3 grams. The blooming period is in the middle of October every year. Petal color white, corolla diameter 3.4 cm, ovary with warbling hairs, calyx outer without hairs, style length 0.9 cm, style division position low, pistil lower than the height of the stamens. The tea polyphenol content of one bud and two leaves in spring is 20.3%, amino acid 3.9%, caffeine 3.2%, and water leachate 46.1%. Suitable for the production of green tea, especially suitable for the production of curly-shaped tea, black tea and other concurrently. For green tea, the shape is tight and tender green, the inner quality is tender and fragrant, the soup color is tender green and bright, the taste is strong and mellow, and the leaf bottom is tender green. For black tea, the shape is tight, with many golden hairs, the soup color is orange-red and bright, the aroma is high and sweet, and the taste is mellow and sweet. In the first growth cycle, the mu yield of one bud and two leaves is 243 kg, which is 2% less than the control 'Fuding Big White Tea'; in the second growth cycle, the mu yield of one bud and two leaves is 288 kg, which is 4% more than the control 'Fuding Big White Tea'. It is resistant to false-eye small green leafhopper, anthracnose, cold resistance, and strong adaptability. [Suitable for planting area and cultivation technology points] Suitable for planting in Sichuan tea area in spring and fall. At an altitude of 1200 meters below the geographical or mountainous areas or double rows of single or double planting, transplanted after the 3 times the stereotypes must be pruned, should be strengthened to cultivate fertilizer management. Pay attention to the prevention and control of small green leafhopper and mite damage.
