In this paper, the leaf, flower, fruit and other 34 phenotypic traits of tea plant from Gu Jing Cun, Nayong County, Bijie City, Guizhou Province,were analysed . The results showed that 10 of the 21 described characters showed only one phenotypes with relatively stable botany characters , and the other 11 exhibited different levels of genetic differentiation. The variation coefficient was between 3.74%-21.86% with the average as 15.10%. The diversity index was between 0.15-2.02 with the average as 1.62. Then the samples can be clustered into 3 groups based on numerical characters, and the 2 and 3 classes has had only 3 samples for each. From those, we suggested that it was necessary to distinguish the lines of class III in the industrialization development, identify the agronomic traits and quality traits and pay attention to biodiversity conservation. In addition, leaf and fruit organs were affected by altitude factors v significantly.Tea plant of Gu Jing have a high breeding potential with the abundant phenotypic diversity and significant genetic variation .
