         Arbor type. Large-leaf size. Early sprouting.

        Originated in the Lechang county (Guangdcng province). It is also distributed in the Renhua, Ruyuan and Qujiang counties.

        Plant high, the maximum height reaches 5~7m. With obvious main stem and rather sparse branching. Plant erect in shape. Leaves horizontal or inflexed. Length 9.9~20.〇cm，width 4.0~9.0cm. Oblong in shape ane light green or dark green in color, glossy, brittle in texture, with acuminate tip. Surface flat or slightly proturding, with neat or waving margin as well as shallow %nd sharp serrations. The sprouting period in the spring season appears in the middle of March. The peak period of shoots with one bud and three leaves stage* appears in the middle of April. Shoots green or light green in color, stout with profuse hairs. The weight of 100 one bud and three leaves shoots averaged 37g. The peak pericd of flowering stage appears in the third ten days of October. The underface of sepal and the surface of young fruit are covered with numerous fine hairs. With medium bearing percentage. High cold-hardiness.

        Rather high yielding. The yield of made tea in the experimental garden of Tea Research Institute, Guangdong Academy of Agricultural sciences averaged 190%225kg per mu.

        According to the analysis conducted by the Tea Research Institute, Chinese Academy of Agricultural Sciences, the contents of caffeine in the shoots at summer season averaged 3.87%, amino acids 1.62%, tea poiyphenols 37.99%, total catechins 225.98 mg/g. The black tea prepared with the GSCT15 variety as the raw material is characterized by its strong aroma and full taste, liquor with 'creaming after cooling*. The green tea prepared with this variety as the raw material has a superb quality and is covered with profuse fine hairs. It was named ‘Baihao Yingzhen.
