[Variety Source] Wufeng Tujia Autonomous County Tea Development Center, etc. Selected from the Wufeng local group of species from a single plant. [Characteristics] Shrub type, early species, strong growth potential, tree posture semi-open, branching density medium, medium leaf type, leaf length 11.4 cm, width 3.6 cm, leaf blade lanceolate, leaf insertion state upward. Spring tea mining period is generally in mid-March, a bud of two leaves in full bloom is generally in late March to early April, the new buds and leaves medium green, velvet hairs, germination density is medium, a bud of three leaves 6.8 cm long, a bud of three hundred buds weight 58.0 grams. Flowering period in early to mid-October every year. The biochemical sample of spring tea buds and two leaves contains 25.9% tea polyphenols, 6.3% amino acids, 3.6% caffeine, 42.7% water leachate.
