摘　　要：[Objective] The aim of this study was to select a tea variety with full aro- ma and high quality. [Method] The quality of Yunchachunhao was identified using Yunkang 10 and Fudingdabaicha as the controls in variety comparison test, using Yunkang 10 and Dangdidayezhong as the controls in reginal test. [Result] In variety comparison test, the yield of Yunchachunhao was 39.3% more than that of Yunkang 10, and 29.6% more than that of Fudingdabaicha. In reginal test, the yield of Yun- chachunhao was 2.5% （Baoshan） and 10.2% （Lancang） more than that of Yunkang 10. The roast-dried green tea of Yunchachunhao was characterized by flowery fla- vor, good taste and bright green infused leaves. It got the total scores of 91.13 in quality identification, which was higher than that of Fudingdabaicha （90.75） and Yunkang 10 （88.85）. The steam fixed green tea of Yunchachunhao contained 28.0% polyphenols and 2.7% amino acids; and the ratio of polyphenols to amino acids was 10.4, lower than that of Fudingdabaicha （10.6） and Yunkang 10 （17.3）. Yun- chachunhao had better resistance to drought and blister blight than Yunkang 10. [Conclusion] The survival rates of cuttings and transplanted seedlings of Yun- chachunhao are higher than that of control varieties, suggesting it has better adapt- ability and can be promoted in the large-leaf tea planting area of Yunnan Province.[目的]选育高香优质绿茶杂交新品种。[方法]通过品种比较试验和区域性试验对对云茶春毫的品质进行鉴定。在品种比较试验中，选择云抗10号和福鼎大白茶作为对照；在区域性试验中,以云抗10号和当地大叶种作为对照。[结果]1992-2010年品比、区试鉴定结果表明：云茶春毫品比产量比对照云抗10号高39．3％，比福鼎大白茶高29．6％，区试产量高于云抗10号2．5％（保山点）及10．2％（澜沧点）。制绿茶具花香显露、滋味鲜爽、叶底绿较亮等品质特点，绿茶品质总分为91．13分，超过对照福鼎太白茶（90．75分）和云抗10号（88．85分）。1芽2叶蒸青样含茶多酚28．0％，氮基酸2．7％。酚氨比值10．4，酚氨比值低于对照福鼎大白茶（10.6）和云抗10号（17．3）。云茶春毫抗旱、抗茶饼病能力超过云抗10号。[结论]云茶春毫扦插繁殖和移栽成活率高于对照品种。适应能力强，在云南大叶茶种茶区推广种植良好。
