[Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2021)510033. [Variety Source] Mabian Yi Autonomous County Agricultural and Rural Affairs Bureau et al. selected from 'Sichuan Zhongxiaoye', Medium and Small Leafed Species,' a monoculture selection. [Characteristics and properties] Small tree type, small-leaved class, medium-grown species. The tree posture is semi-open, the growth potential is medium, the branching part is low, and the branching density is medium. The leaf blade is horizontally inserted, the shape of the leaf blade is narrowly elliptic, the length of the leaf blade is 8.2 centimeters, the width is 2.8 centimeters; the color of the leaf is yellow, and the shape of the apex of the leaf blade is obtuse. 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 second half of March; the germination density is medium, the velvet is medium, and the color of the new shoots in summer and autumn is golden; the length of one bud and three leaves is 6.3 cm, and the weight of one hundred shoots is 22.4 g. The flowering period is in the second half of September every year. The blooming period is in late September every year. The biochemical sample of one bud and two leaves in spring contains 15.1% tea polyphenols, 7.8% amino acids, 4.7% caffeine, 43.4% water leachate. Suitable for green tea. The system of baking green tea, the sensory quality of color and lustre “three yellows” prominent, that is, dry tea golden yellow, soup color tender yellow, leaf bottom jade yellow, appearance of the buds and leaves into a uniform, tender aroma with milk flavor, soup color tender yellow and bright, fresh and crisp flavor, leaf bottom jade yellow and bright. In the first growth cycle, the mu yield of fresh leaves of one bud and two leaves is 378 kg, which is 5% less than the control 'Fuding Dabaicha'; in the second growth cycle, the mu yield of fresh leaves of one bud and two leaves is 385 kg, which is 3% less than the control 'Fuding Dabaicha'. According to the resistance appraisal in three consecutive years from 2016 to 2018: susceptible to small green leafhopper, moderately resistant to anthracnose, and comparable to the control 'Fuding Dabaicha' in terms of resistance to (cold) drought. [Suitable for planting area and cultivation technology points] Suitable for planting in the southwest ecological zone of Sichuan tea area below 1000 meters above sea level in the sunny flat or mountainous areas. Select the soil with medium or high fertility, suggest double rows of single plants, need to carry out 3 times of stereotypes pruning; strengthen the nutritional regulation, should not be heavy nitrogen fertilizer; strengthen the management of pest and disease green prevention and control.
