[Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2024) 450010. [Variety Source] Selected by Guangxi Institute of South Subtropical Agricultural Science from a single plant of 'Nanshan Baimao Cha' in Guangxi. [Characteristics and properties] Small tree type, medium leaf type, early growth species. The tree posture is erect, the growth potential is medium, the branching part is medium, the branching density is medium. The leaf blade is horizontally inserted, moderately elliptic, 8.6 centimeters long, 3.7 centimeters wide, the leaf color is moderately green, and the apex is sharp. In Longzhou area of Guangxi, the exploitation period is generally in early March, and the full bloom period of one bud and two leaves is generally in the middle of March; the germination density is medium, and the velvet is medium; the length of one bud and three leaves is 6.8 centimeters, and the weight of one bud and three leaves in one hundred buds is 90.3 grams. The bloom period is in the middle and end of December every year. The biochemical sample of spring tea bud two leaves contains 25.0% of tea polyphenols, 2.4% of amino acids, 5.5% of caffeine, 51.6% of water leachate. Suitable for green tea. Baked green tea, the shape is tight, slightly curly, slightly hairy, green, light yellow soup color, slightly dark, aroma of rich nectar fragrance, taste is still thick and mellow, more sweet and slightly astringent, the bottom of the leaf is soft and uniform, slightly bud, dark green. The first growth cycle mu yield of one bud and two leaves 311 kg of fresh leaves, than the control 'Fuding Dahaocha' yield reduction of 8%; the second growth cycle mu yield 517 kg, than the control 'Fuding Dahaocha' yield reduction of 8%. It is highly resistant to anthracnose, susceptible to small green leafhopper, moderately drought-resistant, and highly cold-resistant. [Suitable for planting area and cultivation technology points] Suitable for planting in the winter and spring in the area of Guangxi where the average annual temperature is 20˚C, the lowest temperature is not lower than -2˚C, the frost-free period is 350 days, and the average annual precipitation is about 1500mm. Choose deep soil, organic matter-rich soil for cultivation, double rows of single-plant “zigzag” planting, mu planting about 4000 plants. Appropriate application of organic fertilizer, timely shaping pruning, batch leaf picking, picking and raising combination. Pay attention to the small green leafhopper control.
