[Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2023)530083. Former Yunnan Provincial Crop Variety Validation Committee Validation No. Yunnan Tea No. 12, formerly known as '73-11'. [Variety origin] Selected by Tea Research Institute of Yunnan Academy of Agricultural Sciences from Yunnan Fengqing 'Zaosheng Yuanye Daye'. [Characteristics] Tree-type, large-leaved, early-born species. The tree posture is open, the growth potential is strong, the branching part is high, and the branching is sparse. The leaf blade is upwardly inserted, moderately elliptic, 16.0 centimeters long, 6.3 centimeters wide, yellowish-green in color, with a sharp apex. In the Menghai area, the exploitation period is generally in the middle of February, and the full bloom period of one bud and two leaves is generally in the middle of February; the germination density is medium, with a lot of velvet; the length of one bud and three leaves is 9.3 centimeters, and the weight of one hundred buds is 147.7 grams. The full bloom period is from early September to mid-September every year, the size of the corolla is 5.2 cm x 5.0 cm, the length of the pedicel is 1.1 cm, the calyx is 5, green and velvet; the petals are 6-8, white in color, medium in texture and velvet; the length of the style is 1.4 cm, the stigma is 3-lobed and shallowly lobed, and the relative heights of the pistil and the stamen are of equal heights. One bud and two leaves in spring contain 32.5% tea polyphenols, 3.2% amino acids, 4.4% caffeine, and 49.2% water leachate. It is suitable for making black tea and Pu-erh tea. When making black tea, the aroma is higher and sweeter, and the flavor is sweeter. When making Puerh raw tea, the aroma is rich with floral flavor, and the taste is strong; when making Puerh ripe tea, the aroma is sweet and old, and the taste is mellow and sweet. The first growth cycle mu yield of fresh leaves of one bud and two leaves is 631 kg, which is 7% lower than the control 'Yunkang 10'; the second growth cycle mu yield is 688 kg, which is 7% lower than the control 'Yunkang 10'. Resistant to anthracnose, moderate resistance to cloudy leaf blight, tea cake disease, moderate resistance to small green leafhopper, resistance to coffee mite, susceptible to thrips, moderate cold tolerance, strong drought tolerance. [Suitable for planting areas and cultivation technology points] Suitable for planting in the southwest ecological zone of Yunnan Xishuangbanna, Pu'er, Baoshan and other tea areas in the rainy season. It is appropriate to use double rows of single plants, 2000 plants per mu; deep digging planting ditch, adequate bottom fertilizer, before planting 4000-5000 kg / mu of farmyard manure; strict 3 times stereotypes pruning. Spring tea sprouting especially early, pay attention to the prevention of inverted spring cold; pay attention to the prevention and control of tea cloud leaf blight, thrips.
