[Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2019)430029. [Variety Source] Single-plant selection from 'Jianghua Kucha' by Tea Research Institute of Hunan Academy of Agricultural Sciences. [Characteristic features] small tree type, middle-grown (late) species, strong growth potential, tree posture semi-open, medium leaf type, leaf blade length 12.0 cm, width 4.4 cm, leaf blade oval, leaf blade attachment state level, leaf color yellow-green shiny, spreading glossy, soft leaf quality. In Changsha area spring tea bud one leaf period in late March or early April, the new buds and leaves yellowish green, less hairy, buds more fat.
