         Plant high, Spreading type in shape, with higher branching position and average branching density. Leaves horizontal or incline upwards. Length 11.0%13.4 cm, width 5.5~5.9 cm. Oblong in shape with acuminate tips. The surface of leaves protruding. Thick and soft in texture. Dark green in color and glossy. With waved margin. 8%9 pairs of veins. The sprouting period in spring season appears in the first ten days to the middle of March. The peak period of one bud and three leaves stag© shoots appears in the end of March to the beginning of April. With uniform sprouting rate, vigorous sprouting ability and rapid growth rate. Shoots stout, light green in color. Average amounts of fine hairs, with potent tenderness-keeping ability. The weight of 100 one bud and three leaves shoots averaged 134.0 g. The peak period of flowering stage appears in the middle of October. With moderate amounts of. flowers. Low bearing percentage. Higher resistance to bud blight. Higher rooting ability during cutting propagation.

          Higher yielding. According to the results of varietial comparative experiment, the yield of GSCT47 variety is 15% higher than that of Yunnan Daye population. The yield of made tea in a large area of 18 years old tea garden averaged 354 kg per mu.

          According to the analyses conducted by the Tea Research Institute, Chinese Aca demy of Agricultural Sciences, the contents of amino acids in the one bud and two leaves shoots averaged 2.22%, tea polyphenols 42.15% and total catechins 250.41 mg/g. The broken black tea prepared with GSCT47 variety as the raw material is characterized by its uniform granule, brownish and living in color, fragrant aroma, full and refreshing taste, bright reddish liquor and infused leaf, is comparable with the standard of exported black tea manufactured by large-leaf variety.
