摘要/Abstract

摘要： 应用AFLP 技术, 对32 个粉蕉、大蕉、龙牙蕉品种进行了遗传多样性分析及分类研究。在分
子水平上, 可将供试品种聚为6 个独立群体, 其中包括3 个分别由单一品种组成的群体(群体Ⅳ: 酸大蕉;群体Ⅴ: 孟变; 群体Ⅵ: 千旁培) ; 可以将群体Ⅰ (大蕉) 和群体Ⅱ (粉蕉) 分别划分为3 个品种群, 将群体Ⅲ (龙牙蕉) 划分为2个品种群。参照Simmonds 的形态学分类方法, 研究结果显示粉蕉、大蕉以及龙牙蕉各个品种之间存在丰富的遗传多样性, 将其划分为AAB 或ABB 等类型, 不能反映品种间的亲缘关系; 粉蕉与大蕉两个类群之间遗传距离差异明显, 将其简单的归为ABB 类型是不妥当的。

Abstract: AFLP analysis revealed that an abundant genetic diversity existed among Musa ABB group Fenjiao, Musa ABB group Dajiao and Musa AAB group Longyajiao. UPGMA analysis showed that 32 Fenjiao , Dajiao and Longyajiao cultivars were divided into 6 groups including 3 groups made of single cultivar. Group Ⅰ(Musa ABB group Dajiao) were divided into three subgroups. Group Ⅱ (Musa ABB group Fenjiao) included three subgroups. Musa
AAB group Longyajiao (Group Ⅲ) were divided into two subgroups. The results showed that Fenjiao , Dajiao , and Longyajiao can not be divided into AAB or ABB group simply because of the abundant genetic diversity existed among them. It will not be able to reflect the genetic relationships among Fenjiao , Dajiao and Longyajiao. There was very significant difference between Fenjiao and Dajiao. It is inappropriate to set Fenjiao and Dajiao into the same ABB group according to Simmonds’system.
