GSCT41 (Yingshuang)

          New clonal variety. Small arbor type. Medium leaf size. Early sprouting.

          It was selected individually from the progenies of the natural hybridization between the Fudiang Dabaicha and Yunnan large-leaf variety in 1956~1979 by Hang-zhou Tea Research Institute (Zhejiang province). Now it has been popularized in the tea area of Zhejiang province. It was also introduced and popularized in the provinces of Anhui, Hunan, Hubei, Guangxi, Guangdong, Henan, Jiangsu, Shanxi and Jiangxi.

          Plant higher. Erect in shape, with higher branching position on the stem and moderate branching density. Leaves incline upwards and slight inflexing. Length 9.2~10cm, width 3.7~4.2 cm. Oblong in shape, yellow-green in color, with acuminate tips. Waved margin as well as shallow and sharp serrations. Soft in texture. 7~9 pairs of vein. The sprouting period in the spring season appears in the first ten days to the middle of March. The peak period of one bud and three leaves appears in the middle of April. With mcxierate sprouting density and potent sprouting ability. With profuse hairs and potent tenderness-keeping ability. The weight of 100 one bud and three leaves shoots averaged 45 g. The peak period of flowering stage appears in the middle to the third ten days of October. With abumdant amounts of flowers and higher bearing percentage as well as high survival rate during cutting propagation.

          High-yielding. The yield of made in an area of 3 mu 4 years old tea garden in the Hecun Tea plantation (Deqing county, Zhejiang province) averaged 256.3 kg per mu. An area of 14 mu 10 years old tea garden in the Hangzhou Tea Experimental Plantation, the yield of made tea averaged 367 kg per mu.

          According to the analysis conducted by Hangzhou Tea Research Institute, the contents of tea polyphenols in the one bud and two leaves shoots in the spring, summer and autumn season averaged 30.52%, amino acids 2.54%, tea catechins 157.54 mg/g and caffeine 3.97%. Suitable to the manufacture of black tea and green tea. The roasted green tea prepared with the GSCT41 variety as the raw material is characterized by its tightly and finely rolled leaf, green in color and rather glossy, full and fresh taste with light green and bright liquor. Suitable to manufacture the congou black tea during the summer and autumn season and is characterized by its tight and glossy leaf, full and fresh taste and fragrant aroma. Liquor red and bright. It is also suitable to manufacture the broken black tea and with higher quality.

          Suitable to popularize in the tea region in. the south-of-Yangzte River for the south-of-Yangzte River for the manufacture of Gongfu black tea and green tea.

          Owing to the erect shape and potent terminal growth rate, it is recommended to plant densely and lower the height of format pruning and increase the times of pruning. For the purpose of minimizing the influence of cold and drought, to select the land faced the south and increase the applied amounts of organic fertilizer during the autumn and v/inter season are necessary, so to increase the cold-hardiners of tea plants. The control of mites and bud blight are important.

【产地与分布】由杭州市农业科学研究院茶叶研究所（原杭州市茶叶科学研究所）于1956~1979年从福鼎大白茶和云南大叶种自然杂交后代中采用单株选育法育成。全国大部分产茶区有引种，浙江、江苏、安徽、江西、河南、湖北、广西、湖南等省区有较大面积栽培。1987年通过全国农作物品种审定委员会认定，编号GS13041-1987。

【形态特征】 植株较高大，树姿直立，分枝密度中等。叶片呈上斜状着生，椭圆形，叶色黄绿，叶面微隆起，叶身稍内折，叶缘波状，叶尖渐尖，叶齿浅密，叶质柔软。花冠直径2.6〜3.2cm，花瓣白色、6~7瓣，子房茸毛中等，花柱3裂。

【特性】 春季萌发早，2012年在杭州观测，一芽二叶期出现在4月6日，比福鼎大白茶早4天。芽叶生育力強，持嫩性强，生长期长，全年可采至10月上旬，黄緑色，茸毛中等，一芽三叶百芽重45.0g。2011年在杭州取样，春茶一芽二叶干样约含茶多酚18.1%、氨基酸5.4%、咖啡碱3.4%、水浸出物44.8%。产量高，每667㎡可产干茶280kg。适制红茶、绿茶。制緑茶，条索细紧，色嫩绿尚润，香高鲜持久，味浓鲜；制工夫红茶，条索细紧，色乌润，香高味浓鲜；制红碎茶，品质亦优。抗寒性尚强。扦插繁殖力强。

【适栽地区】江南绿茶、红茶茶区。

【栽培要点】可采用双行条栽茶园规格种植，适时定型修剪，摘顶养蓬。在高山茶区宜选择向阳地块种植，并在秋、冬季增施有机肥，提高抗寒力。及时防治螨类、芽枯病。
