The agronomic traits, made tea quality, chemical components, cold tolerance and resistance to pests and diseases of 500 accessions tea germplasms collected from Yunnan Province were systematically and comprehensively investigated during 1986~2005. A total of 52 well-performed accessions tea germplasms were screened out according to nearly 100 characteristics. Among which, 32 accessions were relatively coordinated polyphenols, amino acids, caffeine and water extract contents, 2 super early maturity, 5 high polyphenols contents(>38%), 7 high caffeine content(>5.2%), 2 high caffeine content(<1%), 10 high theaflavins content(>1.6%), 26 high water extracts content(>48%), 2 high resistant to root knot nematode, 1 high resistant to tea leafhopper, 2 high resistant to tea red spider mite and 6 strong cold tolerance germplasms.
