GSCT42 (Cuifeng)  New clonal variety. Small arbor type. Medium leaf size. Medium sprouting.

        It was selected individually from the progenies of natural hybridizatioa between the Fuding Dabaicha variety and Yunnan Daye variety in 1956~1979 by Hangzhou Tea Research Institute. Now it has been popularized in the tea area of Zhejiang province and introduced to the provinces of Anhui, Hubei, Jiangsu, Jiangxi, Guizhou, Guangxi and Henan.

        Plant higher. Semi-opened in shape with higher branching density. Leaves hori-zontal，length8.2~9.1cm，width 3.0~3.3 cm. Long-oblong in shape and dark green in color. Thick in texture and slightly inflexing. With acuminate tips and waved margin. 7%8 pairs of vein as well as uniform serrations. The sprouting period in the spring season appears in the middle to the third ten days of March. With higher sprouting density and potent sprouting ability. Shoots rather stout and green in color. The weight of 100 one bud and three leaves shoots averaged 46g. The peak period of flowering stage appears in the first ten days of November. With less flo-wers. Tolerant to frost and drought. With wider adaptabiKty. High survival rate dur-ing cutting propagation.

        High yielding. The yield of made tea in a 12 years old tea garden in the Hangzhou Tea Research Ihstitute averaged 301 kg per mu.

        According to the analysis conducted by Hangzhou Tea Researdh Institute in 1979, the contents of tea polyphenols in the one bud and two leaves shoots in the spring, summer and autumn season averaged 28.21%, amino acids 3.43%, total cate-chins 144.92 mg/g and caffeine 3.72%. Suitable to the manufacture of green tea. The roasted green tea and Yingfeng green tea prepared with the GSCT42 variety as the raw material is characterized by its tightly and finely rolled leaf, green and glossy with fine hairs, fragrant aroma as well as fresh taste. With light green and clean liquor as well as bright and green infused leaf. Tne Japenese Yulu tea (Cuifeng Yulu) prepared with this variety in china is characterized by its tightly and finely rolled leaf, light green in color, rather glossy, with fine hairs, fragrant aroma with strong, refreshing and sweet taste, clean greenish liquor and infused leaf.

        Suitable to popularize in the tea region in the south-of-Yanzhe river for the manufacture of green tea.

        Due to the slower growth rate during the seedling stage and average tenderness keeping ability, it is recommended to increase the applied amounts of fertilizers and strength the management of tea garden. Plucking in time and the control of spiny Citrus blackfly as well as sooty mould disease are necessary.
