[Variety Number] Non-major crop variety registration No. GPD Tea Tree (2022)510047. former Sichuan Crop Variety Validation Committee Validation No.: Sichuan Validation Tea 2013001. [Variety Source] Selected by Sichuan Agricultural University and others from a single strain of 'Sichuan Zhongxiaoye'. [Characteristics] Shrub type, medium leaf type, early growing species. The main stem of the plant is not obvious, the posture is semi-open, the growth potential is strong, the branching part is low, the branching density is medium. Leaf length 7.9 centimeters, width 3.7 centimeters, leaf blade narrow elliptic, leaf insertion state horizontal, leaf edge microwave, into the leaf green, glossy strong. In Sichuan Ya'an tea area germination than the control 'Fuding Dabaicha' 2-4 days earlier, germination neat, and germination density is high, bud stalks hair less; spring, summer and fall tips were green, are no purple buds. The length of one bud and three leaves is 7.4 centimeters, and the weight of one hundred buds is 49.9 grams. Flowering period is in late October every year, no stalks on the outside of the calyx, the ovary has velvet hairs, the number of stigma splits is 3, the pistil is higher than the stamen, and there are few fruits and flowers. The biochemical sample of one bud and two leaves of spring tea contains 17.0% of tea polyphenols, 5.1% of amino acids, 3.6% of caffeine, and 57.9% of water leachate. Suitable for green tea. Spring baking green tea, the appearance of tight fine, emerald green hair, the inner quality of the tender fragrance of high long, fresh and strong flavor; summer tip of the baking green tea, chestnut fragrance of high long, taste fresh and sweet, bitter and astringent taste is light. The first growth cycle mu yield of one bud and two leaves 324 kg of fresh leaves, than the control 'Fuding Dabaicha' 12% increase in yield; the second growth cycle mu yield of one bud and two leaves 413 kg of fresh leaves, than the control 'Fuding Dabaicha' 14% increase in yield. It is moderately resistant to false-eye small green leafhopper, and moderately resistant to anthracnose. Drought resistance in Sichuan tea area is medium, cold resistance is strong. [Suitable for planting area and cultivation technology points] Suitable for planting in Sichuan, Chongqing tea area at an altitude of 1200 meters or less. Due to the vigorous growth of this variety, germination density is high, it is recommended to single row or double row single planting, planting density 3000-4000 plants / mu, and strengthen the tea garden fertilization management.
