| Abstract: | In order to probe into the adaptability including survival rate, spring phenophase, biochemical components, quality of green tea, cold resistance, 23 tea cultivars bred in Hunan, Sichuan, Zhejiang, Fujian, Anhui and Taiwan were planted in Changsha. The results showed that 4 cultivars reached the level of ultra-early budding in one-leaf-and-one-bud shoots, 12 cultivars reached the level of early budding; the contents of amino acid in spring ranged from 3.67% to 6.23%,among which 6 cultivars exceeded 5%,the contents of tea polyphenol ranged from 17.23% to 26.23%,the contents of caffeine ranged from 3.36% to 4.87%, tea polyphenol/amino acid<7,10 cultivars were more excellent than the others in quality of green tea, and cultivars from Hunan province have advantage compared to the others from the areas outside of Hunan,8 cultivars were stronger than the control in cold resistance. |
