摘　　要：在广西钦州市钦北区新棠镇进行田间试验 ,观测“钦州红荔”株系和“黑叶”、“香荔”品种单株的植株形态和果实性状表现 ,采集营养梢老熟叶片进行过氧化物酶 (POD)同工酶分析。结果表明 :“钦州红荔”植株形态和果实性状保留有“黑叶”和“香荔”品种单株的一些特性 ,该株系早结丰产、果形特大、果皮鲜红色、品质优。叶片 POD同工酶分析 ,它们具有相似遗传基础、迁移率 (Rf)为 0 .33和 0 .5 4的 2条特征酶带 ,初步鉴定认为“钦州红荔”株系是“黑叶”和“香荔”单株的自然杂交实生优良后代。The field test was carried out in Qinzhou city of Guangxi for investigating characteristics of Litchis Qinzhou Red Litchi, Black Leaf and Xiang Litchi and their peroxide(POD) isoenzyme were analysed. The new strain Qinzhou Red Litchi retains several main characteristics of other two varieties of Black Leaf and Xiang Litchi,with early fruit,high yield,large fruit form, bright red rind and excellent quality. The POD isoenzyme from leaves displayed two characteristic enzyme bands with resemble genetic foundation and removed rates of Rf 0 33 and Rf 0 54 respectively.Qinzhou Red Litchi is regarded as a natural hybrid progeny. Its parents were Black Leaf and Xiang Litchi.
