| 摘 要： | 选用两对引物组合EcoRⅠ ACT+MseⅠ CTT和 EcoRⅠ ACT+MseⅠ CTC对46份龙眼材料进行AFLP分析，共得到扩增位点111个，其中多态性位点103个，多态性比例达92.69%，区分率达100%。对AFLP扩增结果进行聚类分析，根据相似系数0.76的水平可将46份龙眼品种(系)分为11个品种群。供试各品种多态性比例介于0.2703和0.4955间。福建东壁与广东东壁应为不同品系；早熟一号为一个新的品系。

| Abstract: | The study is mainly on the genetic diversity and relationship of Longan (Dimocarpus longan Lour．) cultivars by applying AFLP (Amplified Fragment Length Polymorphism). 103 polymorphic distinct bands were obtained with two pairs of primers(EcoRⅠACT+Mse ⅠCTT and EcoR ⅠACT+Mse Ⅰ CTC)，which were enough to distinguish the 46 cultivars from each other. UPGMA analysis showed that 46 cultivars were divided into 11 groups．The ratio of polymorphic rate varied from 0.2703 to 0.4955．The result showed that the Fujian Dongbi
was diferent from Guangdong Dongbi and they were different types from Kaiyuansi Dongbi．Zaoshu 1 was supposed to be a new type．The results supplied theoretical basis for cultivar classification． |
