[Breeder] Zhang Lei; Chen Zhizhi; Yang Ruxing; Wu Zhidan; Yu Ying. [Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2024)350045. [Variety Source] Fujian Provincial Academy of Agricultural Sciences, Tea Research Institute from Shouning County, Fujian Province, Fujian Province, Wuchu Township, the local vegetable tea from a single plant selection. [Characteristics] Small tree type, medium leaf type, early growth species. Tree posture upright, strong growth potential, branching site, branching dense. Leaf blade upward bearing, narrow oval, leaf blade length 10.1 centimeters, width 3.9 centimeters, leaf color dark green, apex sharp. The exploitation period is usually in the middle of March, and the full bloom period of one bud and two leaves is usually in the middle of March, with high germination density, more velvet, and the length of one bud and three leaves is 9.7 centimeters, and the weight of one hundred buds is 97.1 grams. The blooming period is in early October every year. The biochemical sample of one bud and two leaves in spring contains 19.1% of tea polyphenol, 4.7% of amino acid, 3.3% of caffeine and 47.6% of water leachate. Suitable for white tea and black tea. For white tea, the appearance of orchid-type gray-green hairy, with fragrance or fragrance, mellow and refreshing taste, yellow-green leaf bottom is bright and even. For black tea, the shape is oolong, fat and tender, with obvious floral aroma, fresh and mellow flavor, red soup color, and the leaf bottom is fat and tender, soft and bright, even. The first growth cycle mu yield of one bud and two leaves 221 kg of fresh leaves, than the control 4 Fuding big white tea '14% increase in yield; the second growth cycle of the spring mu yield of one bud and two leaves 229 kg of fresh leaves, than the control 'Fuding big white tea' 10% increase in yield. It is resistant to small green leafhopper, tea anthracnose, drought and cold resistance. [Suitable for planting area and cultivation technology] Suitable for planting in Fujian tea area in fall or spring. Double rows and double columns cross planting, mu planting 4000-5000 plants. Juvenile annual shearing 1-2 times, mining, pay attention to stay leaf picking, picking and raising combination, promote sprouting buds, can be early to form a high-yield canopy. After the garden to strengthen the fertilization management, can give full play to its early yield and high yield characteristics. Because of the early reproductive period of the new shoots, it is necessary to guard against the early spring “spring cold”.
