[Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2023) 450066. Former Guangxi Crop Variety Registration No. (Gui) Deng (Tea) 2010004. [Variety Source] Breeding from a single strain of 'Lingyun Baimao Cha' by Tea Scientific Research Institute of Guangxi Zhuang Autonomous Region. [Characteristics] Small tree type, medium leaf type, early variety. The tree posture is semi-open, with strong growth potential, medium branching part and dense branching. Leaf blade upward bearing, narrow oval, 6.8 cm long, 2.9 cm wide, leaf green, apex obtuse. The exploitation period in Guilin is generally in late February, and the full bloom period of one bud and two leaves is generally in late February to early March; the germination density is high, and the velvet is medium; the length of one bud and three leaves is 7.9 centimeters, and the weight of one bud and three leaves in one hundred buds is 50.0 grams. The blooming period is in the middle and end of November every year. The biochemical sample of one bud and two leaves in spring contains 17.0% of tea polyphenol, 4.1% of amino acid, 3.4% of caffeine and 43.2% of water leachate. Suitable for green tea and black tea. Make green tea, appearance green with hair, soup color green, aroma high sharp, taste strong and fresh; make black tea, color brown, soup color red, flower aroma high pure, taste thick and fresh. The first growth cycle mu yield of one bud and two leaves of fresh leaves 387 kg, 11% higher than the control 'Fuding Dabaicha'; the second growth cycle mu yield 424 kg, 11% higher than the control 'Fuding Dabaicha'. It is resistant to tea anthracnose, tea leafhopper, drought resistance and cold resistance. [Suitable for planting area and cultivation technology points] Suitable for planting in Guangxi, Sichuan, Fujian tea area in the spring. Because of the early species, it is appropriate to plant with the middle and late varieties, 6000-8000 seedlings per mu; young period to fertilize the main, 10 kg per mu per application of compound fertilizer, winter additional organic fertilizer, fertilizer 4 times a year in the productive period. The variety of tree type partial upright, buds and leaves strong apical dominance, the young age of the tea garden of the stereotypes of pruning should be divided into 4-5 times, in order to promote the growth of lateral branches, accelerate the cultivation of backbone branches, to achieve the early closure of the garden. The picking standard is one bud and one leaf or one bud and two leaves.
