| 摘 要： | 以经N+离子诱变后的槠叶齐茶种子为原始材料，经系统选种和无性繁殖，育成了早生优质抗寒茶树良种茶农1号。经1998—2003年品种比较实验，结果表明：该品系春季萌发期特早，与对照皖农95相比，同期萌展值大0.39~0.96，与福鼎大白茶相比，同期萌展值大0.35~0.57；鲜叶中生化成分含量丰富，其中多酚含量28.22%、氨基酸含量1.51%，咖啡碱含量4.81%，水浸出物含量44.82%，茶多糖含量1.55%；各成分比例协调，绿茶品质佳，尤以香气和滋味表现突出；抗寒性强，对倒春寒的抗性也强。实验结果提示：N+注入是一种有效的茶树良种选育方法。 |

| Abstract: | The clone seeds of Chuyeqi were induced by N implantation, and an Early-sprouting ,Cold-resistance and Quality improved tea cultivar "Chanong NO.1" has been selected by means of systematic selection and vegetative propagation. Based on the cultivar comparative test carried out in 1998-2003, "Chanong NO.1" sprouted very early in spring and the sprouting values were 0.39~0.96 higher than the control cultivar Wannong95, and 0.35~0.57 higher than Fuding -dabaicha .The content of tea chemic material was abundant in fresh leaves and the contents of tea polyphenols, caffeine, amino acids, polysaccharides and resoluble material were 28.22%, 4.81%, 1.51%, 1.55% and 44.82%. Moreover, their ratios were harmonious, resulted in its excellent quality of the made green tea especially in the aspects of aroma and taste. "Chanong NO.1" was strong in cold resistance, especially during the spring frost season. Thus a conclusion may be drawn that it is an effective way of breeding quality tea cultivar by N implantations. |
