GSCT33  (Fuyun 6) ，Alternative name: Fuyun 58-6 . Clonal variety. Small arbor type. Large-leaf size. Extremely early sprouting.                        

It was selected individually from the natural hybrid between Fuding Dabaicha vaiiety and Yunnan Daye variety in 1957~1971 by the Tea Research Institute, Fujian Academy of Agricultural Sciences. It has been widely cultivated in the tea region of Fujian province and introduced ;n a limited area of Zhejiang, Hunan, Sichuan, Guizhou and Hubei provinces.      

Plant tall, it can be reached as tall as more than 4-5 m. under natural growing conditions. The position of branching on the stem is rather high. Semi-opened type, with rather dense branching density. Leaves horizontal or drooping, length 11~13.2 cm, width 4.3~4.9 cm. Oblong or long oblong in shape, with acuminate tips and slightly protruding on the surface. Light green in color, lack of glossy, thick and bristle in texture. Waved margin as well as fine and shallow serrations. Leaves incline inwards. 9~11 pairs of veins. The sprouting period in spring season appears in      the beginning of March. The plucking period of one bud and three leaves shoots appears in the third ten days of March. With uniformly sprouting date and higher sprouting density. Potent sprouting ability. Shoots stout, light yellow-green in color, with profuse hairs. The weight of 100 one bud and three leaves shoots averaged 69g. The peak period of flowering stage appears in the third ten days of November. With numerous flowers and rather higher bearing percentage. With wide adaptability. Higher cold-hardiness and higher resistance to drought and infertile conditions. Potent,      rooting ability during cutting propagation. The seedlings grow quickly, easy to cultivate and earlier to establish into productive.                   

High-yielding. According to the results of comparative experiment on different varieties, the yield of made tea of 4~8 years old tea plant averaged 213.6 Kg, and  40.8% higher than that of Fuding Dabeicha.              

Suitable to manufacture of black tea and green tea. The Gongfu black tea prepared with GSCT33 variety as the raw material is characterized by its elegant and tightly rolled leaf with profuse hairs, bloom in color, full taste as well as reddish and bright   infused leaf. The green tea prepared with this variety shows high aroma, full taste, green liquor and light green infused leaf.                  

Suitable to popularize in the tea region in the south-of-Yangzte River for the manufacture of black tea and green tea. Owing to the erect habit of plant, it is recommended to reduce the row spacing      and 3~4 times of format pruning within the 2~3 years after planting. It is important to pluck in time due to the low tenderness-keeping ability of shoots.
