The weight of 100 one bud and three leaves shoots averaged 33.0 g. The peak period of flowering stage appears in the middle of October. With high bearing percentage. High resistance to frost injury and wide adaptability.

         Rather high-yielding. In an area of 1470 mu tea garden in the Yangxian Tea Plantation (Yixing county, Jiangsu province), the yield of made tea averaged 144.5 ~153.5 kg per mu in 1975~1979. The yield of made tea in 1980 averaged 157.5 kg per mu.

         According to the analysis conducted by the Wuxi Tea Variety Research Institute (Jiangsu province), jhe contents of caffeine in the one bud and two leaves shoots in spring or summer season averaged 3.74%, amino acids 2.91%, tea polyphenols 29.11% and total catechins 177.68 mg/g. Suitable to manufacture the green tea and showed superb quality.

         Suitable to popularize in the tea region in the south-of-Yangzte River and nor-th-of-Yangzte River for the manufacture of green tea.
