摘要(Abstract)：

采用rep-PCR技术,对从我国9省(区)收集、分离、筛选的18株柑橘溃疡病菌株进行遗传多样性研究,并与A菌系标准菌株进行UPGMA聚类分析和相似性分析。结果表明,使用引物BOXA1R扩增供试菌株,可得到不同的条带31条。以遗传相似距离0.4划分,供试菌株可划分为5个簇;以遗传相似距离0.5划分,供试菌株可划分为4个簇;15个菌株与标准A菌株遗传相似距离较近,菌株CJX、CZJ1、CGDN2与标准A菌株遗传相似距离较远;来自同一省的少数溃疡病菌株的遗传相似性也较低,说明我国柑橘溃疡病菌基因组存在丰富的遗传多样性。

关键词(KeyWords)： 柑橘溃疡病菌;rep-PCR;遗传多样性
