[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.
