Abstract: The anatomy structures of leaves of 13 strains of wild tea Camellia sinensis from Guangxi were studied via paraffin-sectioning and optical microtechnique to explore the potential productivity, tea-making suitability, and anti - adversity. The results showed that the potential productivity index of wild tea ranged from 2 471.31 to 4 295.05, revealing a higher value than that of other new wild tea strains of Guangxi. These strains were suit for making black tea, which were in accordance with the highly contents of tea polyphenols. Moreover, the leaves indicated strong resistance, including abilities in anti-drought, anti-cold, and anti-pest. Further, productivity variations among various strains were detected. The strain of Guliao #41, #37, #39 had high productivity index, strong resistance ability and black tea-making suitability.
