摘　　要：利用RAPD技术分别对分离自黑龙江省各地区的90株链格孢属病原菌进行了遗传多样性分析。利用NTSYS 2.0进行链格孢属病原菌的聚类分析。RAPD分析结果表明，引物OPE-19扩增后产生的各个群体间相似性系数分布在0.60~1.00。在68.0%相似性水平上可划分为3个主要RAPD组群和8个次要RAPD组群。聚类分析结果表明，黑龙江省链格孢属病原菌RAPD组群与寄主植物和分离地区之间没有相关性。To understand the genetic diversity of 90 Alternaria pathogen isolates col ected from Heilongjiang Province, the genotypic characteristics was performed by using random amplified polymorphic DNA （RAPD）, and cluster analysis of Alternaria pathogens was carried out by using NTSYs program. RAPD results indicated that the similarity coefficients of RAPD group amplified by the primer OPE-19 ranged from 0.60 to 1.00. According to RAPD analysis by using the primer OPE-19, 90 isolates were separated into three major RAPD groups and eight minor groups at the similarity level of 68.0%. The cluster analysis results suggested that RAPD groups not be correlated with the host plants and locations where the isolates were col ected.
