摘　　要：鉴定评价了200份种质资源的农艺性状、加工品质、生化成分、抗寒性等。筛选出品质超过国家品种的优异资源6份、茶多酚含量>38％的资源4份、咖啡碱含量>5.2％的资源6份、咖啡碱含量<1.0％的资源2份。对资源扦插后代的DNA多态性、同工酶酶谱特征以及花粉形态结构研究表明,无性后代的遗传性基本稳定。The agronomy, made tea quality, chemical components, cold resistance of 200 accessions of tea germplasms were investigated during 1996-2000. Among six accessions of elite tea germplasms, their made tea quality exceeded national clones, four with high polyphenol content (>38%), six with high caffeine content (>5.2%) and two with low caffeine content (<1%) germplasms were selected. Based on the studies of RAPD marker, isozyme and pollen morphology, the heredity of tea germplasms and their cutting offsprings was basically stable.
