[Variety Source] Selected by the Tea Research Institute of Fujian Provincial Academy of Agricultural Sciences from a single strain of the natural hybrid progeny of 'Huangdan'. [Characteristics] Shrub type, late-blooming species, growth potential in the tree posture semi-open, leaflets, leaf length 6.6 cm, width 2.9 cm, leaf blade medium oval, leaf bearing state upward. In Fujian Fu'an area spring tea bud two leaves in full bloom generally in mid-April, new buds and leaves yellowish-green, velvet in the buds and leaves, a bud of three leaves 10.3 centimeters long, a hundred buds weighing 74.0 grams.

The first growth cycle spring mu yield of one bud and three leaves of fresh leaves 136 kg, 4% yield reduction than the control 'Huangdan'; the second growth cycle spring mu yield of one bud and three leaves of fresh leaves 133 kg, 10% yield increase than the control 'Huangdan'. Medium resistance to tea anthracnose, tea small green leafhopper, cold resistance and drought resistance is medium. [Suitable for planting area and cultivation technology] Suitable for planting in Fujian oolong tea and green tea planting area in spring and fall. It is recommended to cultivate strong seedlings, open deep ditches, apply sufficient bottom fertilizer, groove planting; timely shearing 3-4 times, strengthen the canopy culture, picking and raising combination, to promote the sprouting of buds, and cultivate high-yield canopy.
