| 摘 要： | 采用ISSR分子标记技术对福建省闽江流域10个野生蕉自然居群的遗传多样性和遗传结构进行分析,结果显示:12条ISSR引物共检测出117个条带,105个多态性条带,多态性百分率为89.7%;野生蕉Nei遗传多样性指数为0.244,Shannon's信息指数为0.381,其中三明野生蕉遗传多样性水平最高,且不同自然居群间遗传多样性指数之间具有显著性差异;总遗传变异系数为0.589,基因流为0.349,居群间的遗传分化程度高于居群内;基于遗传距离的聚类结果与模型聚类结果均聚为3大类,分别为沙溪支流的三明野生蕉类群、闽江上游及附近支流的南平野生蕉类群和闽江下游的福州野生蕉类群。研究认为,闽江流域野生蕉资源丰富的遗传多样性主要来源于自然居群间生境异质化所引起的高频率遗传变异,且三明野生蕉类群的遗传多样性和遗传分化程度最高,可能是福建野生蕉的起源中心,也是野生蕉资源开发和利用的最主要群落。此外,水流是闽江流域野生蕉遗传迁移最关键的自然主导因素。
