[Variety Origin] Selected by Tea Research Institute of Chinese Academy of Agricultural Sciences from the seed progeny of 'Jia Ming 1' as a single plant. [Characteristics]: Shrub type, extra-early-born species, erect posture, medium leaf type, leaf blade length 7.9 cm, width 3.5 cm, leaf blade medium oval, leaf blade attachment state upward. In Shengzhou area, the spring tea bud one leaf period is in the middle and late March, the new buds are yellowish green, with few hairs, and the length of one bud three leaves is 6.6 centimeters, and the weight of one hundred buds is 43.5 grams.

Highly susceptible to tea small green leafhopper, resistant to tea anthracnose, resistant to cold and drought. The variety of selenium polymerization ability is strong, under the same conditions, for 2 consecutive years, the average content of selenium in the tea leaves of one bud and two leaves is 27% higher than the control group (the average value of 20 breeding varieties). [Suitable planting areas and cultivation techniques] It is suitable for planting in the Jiangnan Ecological Zone, Zhejiang Shengzhou, in the fall or spring when rainfall is more abundant. It is suitable to adopt the planting specification of single-row double-plant or double-row single-plant, and prevent and control tea leafhopper at the right time; pay attention to the prevention of inverted spring cold and timely picking for the extra-early-born varieties.
