：The comparison test and the reginal experiment of 6 new clones including Zhongcha 108 (RadiationII) and 4 cultivars including Zhongcha 102 were carried out. The results of the comparison test showed that Zhongcha 108 was ultra-early budding clone. The content of amino acid of Zhongcha 108 was as high as 4.53% , it was suitable for the manufacture of green-tea and the quality of made-tea was excellent. Its yield was 67.23% higher than that of Fuding Dabaicha (CK). The result of regional experiment indicated that Zhongcha102 was early budding cultivar, the content of amino acid was 4.46%, it was suitable for the manufacture of green-tea and the quality of tea was excellent, the yield was 21.68% higher than that of Yingshuang (CK). The growth rate of Zhongcha 102 is vigorous and with strong cold resistance.
