从农艺性状、加工品质、生化成分、抗性等方面,对云南500份茶树种质资源进行了全面系统的鉴定和评价。采用近100项评定指标,筛选出52份优质资源,其中：四项常规成分含量均衡的32份;发芽特早生的2份;超常规水平的高多酚（>38%）含量5份、高咖啡碱（>5.2%）7份、低咖啡碱（<1%）的2份、高茶黄素（>1.6%）10份;水浸出物含量>48%的26份;抗根结线虫较强的2份;抗假眼小绿叶蝉较强的1份;抗咖啡小爪螨虫较强的2份;抗寒性较强的6份。

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.
