[Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2021)330041, Plant Variety Right No. CNA20151400.3. [Variety Source] Tea Research Institute of the Chinese Academy of Agricultural Sciences et al. obtained the variety from the 'Zhongcha 108' x 'Longjing 43' artificial hybrid progeny. [Characteristics and traits] Shrub type, early-blooming species, semi-open posture, strong growth potential, medium leaf type, leaf blade length 9.5 cm, width 3.0 cm, leaf blade narrowly elliptic, leaf blade insertion state upward. In Hangzhou and Shengzhou, the spring tea bud and two leaves bloom in mid-March, the new buds and leaves are light green, with few hairs, and the length of the bud and three leaves is 6.8 centimeters, and the weight of one hundred buds is 35.0 grams. Spring tea bud two leaves biochemical samples containing tea polyphenols 19.7%, amino acids 5.2%, caffeine 4.0%, water leachate 48.6%. Suitable for green tea and black tea. The system of curly green tea, the shape of the strong knots show hair, high aroma with fresh flowers, taste sweet and fresh. Black tea production, the aroma of flowers and fruits. The first growth cycle of spring mu yield of one bud and two leaves 98 kg of fresh leaves, 9% yield increase over the control 'Longjing 43'; the second growth cycle of spring mu yield 81 kg, 4% yield increase over the control 'Longjing 43'. It is susceptible to tea leafhopper, highly resistant to tea anthracnose, and strong in cold resistance and drought resistance. [Suitable for planting area and cultivation technology] Suitable for planting in Zhejiang area in spring, fall and winter. It is appropriate to use a single row of double or double row of single planting specifications, tree width, can be appropriate to reduce the planting density. The variety of vigorous growth potential, early germination, before the winter need to prune the prominent branches, to prevent frostbite due to the top buds and reduce yields.
