Traits: Strong bud-developing ability, dense sprouting, tolerant of plucking, and good in yield. In trial planting in Hangzhou, it increased yield by 2097% compared with the control cultivar Yingshuang. Cold-resistant. Strong drought resistance. Under the condition of -11.1 degrees C, the cold resistance of this cultivar is significantly higher than that of the control cultivar. According to biochemical determination, the amino acid content in one bud and three leaves of spring tea of this cultivar reaches 4.46%, tea polyphenols 22.45%, caffeine 3.28%, water extract 40.61%, and the phenol-ammonia ratio is 485, among which the amino acid content is increased by 023 percentage points compared with the control cultivar.
