Qiancha No.8 is a new clonal green tea cultivar which is bred from the excellent individual plant in the Kunmingzhongye tea population via systematic selection and asexual propagation. The test results in different sites and years showed that the germination period of Qiancha No.8 was early in spring(about 5 to 8 d earlier than the CK Fudingdabaicha), the buds and leaves were plump, the branches were dense, and the yield was similar to that of the CK. The water extract, tea polyphenols, caffeine, free amino acid contents of one bud and two leaves steamed samples were 43.8%, 16.7%, 3.4% and 4.9%, respectively. Its ratio of total polyphenols to total amino acids was lower than that of the CK, which was suitable for making high quality green tea. Additionally,Qiancha No. 8 had a very strong resistant capability. It is suitable to be cultivated in Guizhou, Hubei, Guangdong,Guangxi provinces and other similar regions.
