Abstract：Through investigating the ancient tea tree community in Jinghong City of Yunnan Province, the community types,distribution and growth status of ancient tea trees were comprehensively found out,inclu-ding the altitude,tree age,tree performance,tree margin,stem diameter,leaf shape,petal characteristics, etc.The morphological and agronomic characters of 88 tea germplasm resources in 1 2 tea regions were statisti-cally analyzed.The results showed that the variable coefficients of 8 agronomic characters ranged from 1 5.51 % to 57.74% in the order of the lowest branch height,leaf area,tree margin,tree height,leaf length, leaf width,corolla diameter,fruit size.The feature vector contribution rates of 4 main components in 1 3 agro-nomic characters accounted for 73.026%,which were 34.830%,15.824%,12.902%,9.470% from the first to the fourth.
