Abstract: In order to provide scientific basis for adaptability of Qianxinan wild tea plant and utilize it rationally, this study was carried out to explicit characters and qualities of spring shoot of Qianxinan wild tea plant. Twenty-two spring shoot of individual tea trees were used as the objects， characters of leaf bud were investigated， biochemical components of one leaf and one bud were also determined. The results showed that the brightness of leaf bud， shoot tenderness-keeping ability and content of pubescence were better. However， different individual tea tree had a great difference in the biochemical components. Contents of tea polyphenol（TP） were ranged from 19.88% to 36.36%， whose mean value was 28.57%. The total contents of free amino acids were from 0.84% to 4.90% and the average value was 2.71%. The caffeine contents were within 1.28%-4.45%. Among 22 kinds of study objects， No.4， No.11， No.13， No.15， No.16 and No.18 were suitable for green tea production， and the appropriate kinds for making black tea was No.5， No.6， No.7 and No.22.
