Ministry of Agriculture and Tea Research Institute, Chinese Academy of Agricultural Sciences. 1990. Collection on the improved tea varieties in China. p.68-69.

GSCT34 (Fuyun 7), Original name: Fuyun 58-7. Clonal variety. Small arbor type. Large leaf size.      Medium sprouting.        It was selected individually from the natural hybrid between Fuding Dabaicha      variety and Yunnan Daye variety by Tea Research Institute, Fujian Academy of Agricultural Sciences in 1957~1971. Now it was widely cultivated in the tea region of Fujian and also introduced to a limited area in the tea region of Zhejiang, Sichuan, Hunan and Guizhou provinces.

Plant tall and erect in shape. Branches stout and rather sparse branching. Leaves horizontal, length 15.2~16.4 cm, width 5.5~5.9 cm. Oblong or long-oblong in shape, with acuminate tips. Leaves smooth and flat with neat margin, yellowish green in color and glossy. 10~11 pairs of vein. Rough serrations. Rather thick and soft in texture. The sprouting period in spring season in the Fuan county (Fujian province) appears in the first ten days of March. The plucking period of one bud and three      leaves shoots stage appears in the Vtst to second ten days of April. Shoots stout, yellowish green in color with profuse hairs. Rather sparse sprouting density and higher growth rate. The weight of 100 one bud and three leaves Shoots averaged 95 g. The peak period of flowering stage appears in the first ten days to the third ten days of November. With moderate amounts of flowers and high bearing percentage. Higher cold-hardiness and resistance to drought. Wider adaptability. Potent rooting ability during cutting propagation.                         

High-yielding. According to the results of comparative experiments, the yield of made tea of 4~8 years old tea plants averaged 216.6kg per mu, and 42 .7% higher than that of Fuding Dabaicha. The yield of 7 years old tea plant averaged 374.8 kg per mu.                                    

Suitable for the manufacture of black tea and green tea. The Gongfu black tea prepared with GSCT34 variety as the raw material is characterized by its stout leaf with obvious fine harirs, bloom color, full taste with characteristic of “Dianhong” as well as the dark reddish liquor. The roasted green tea prepared with this variety is characterized by its tight and stout leaf with silvery fine hairs as well as yellowish  green and clear liquor. The jasmine tea prepared with GSCT34：(Fuyun Maojion) shows superb quality and appearance.

Suitable to popularize in the tea region in the south-of-Yangzte River for the manufacture of black tea and green tea. Owing to the erect habitat of tea plant, it is recommended to reduce the row spacing, increase the times of format pruning. Besides, it is important to pluck in time due to the shoots is stout in size and with high growth rate.
