【摘要】 以福鼎大白茶与云南大叶种自然杂交后代为原始材料，经系统选种和无性繁殖，育成了早生、优质、适制绿茶的良种“浙农１３９”。经１９８６～１９９５年品种比较试验，结果表明，该品系与福鼎大白茶相比，春季萌芽期早，同期萌展值大０．０５～０．７８；绿茶品质得分高２．９分，尤以香气、滋味表现突出；氨基酸含量高２８．２％，茶多酚含量高１４．６％；５年平均产量高２７．１％，差异显著；抗寒性、抗病性差异不大，抗虫性较弱。更多还原

【Abstract】 An early sprouting and quality line“Zhenong 139”,suitable to green tea,has been selected by means of systematic selection and vegetative propagation from the natural hybrid of Fuding Dabaicha and Yunnan Dayezhong.Based on the variety comparative test carried out in 1986-1995,the selected line sprouts earlier in spring(the sprouting value is 0.05-0.78 greater )compared with Fuding Dabaicha,the CK parent.Moreover,the fresh leaves of the selected line contains 28.2% higher amino acids and 14.6% higher tea polyphenols,resulting in a 2.9 higher score of the made green tea(especially in the aspects of aroma and taste).The 5 year average yield of the selected line is 27.1% higher than that of the CK parent,reaching a significant level.No significant differences existed between the cold resistances and between the disease resistances of the selected line and the CK parent.The selected line possesses a weaker insect resistance,however,than the CK parent.更多还原
