GSCT45 (Zhenong 12)， New clonal variety. Small arbor type. Medium-leaf size. Medium sprouting.
It was selected individually from the progenies of natural hybridization between the Fuding Dabaicha variety and Yunnan Daye variety in 1963~1980 by Zhejiang Agricultural University. Now it has been popularized in the part of the tea area of Zhejiang province. It was also introduced to the limited area of Anhui, Shanxi, Guangxi, Guizhou, Hunan, Jiangxi and Jiangsu provinces.

High resistance to drought and weak cold-hardiness.
High-yielding. According to the comparative varietial experiment carried out in the period of 1974~1979，the yield per unit area is 41.9多 higher than that of Fu-dian Dabaicha variety.

It is recommended to select the lands faced to south as well as protect from wind and with deep soil layer as the tea garden. For the purpose of increasing the cold-hardiness, it is necessary to raise the seedlings with polythene sleeve method and to mulch during the seedling stage Earthing up as well as increasing the amounts of organic fertilizer are important also. Lower the height of pruning and carry out the segmental format pruning in the 2~3 years after planting or combined with the method of branching-benching, so as to promote the expansion of bush canopy.
