摘要
[目的]探明我国北部地区污黑腐皮壳菌的基因多态性、遗传相关程度及其亲缘关系。[方法]对我国北部9个省23个市县的30株污黑腐皮壳菌进行了培养性状和遗传多样性聚类分析。[结果]根据培养性状聚类分析结果,可将30株污黑腐皮壳菌分为东北(黑吉辽)地理群、山东地理群、内蒙古自治区地理群和青海甘肃地理群。根据RAPD聚类分析结果,可将30株污黑腐皮壳菌分为黑龙江省地理群、吉林内蒙古自治区地理群、山东陕西地理群、辽宁地理群、青海地理群和甘肃山西地理群。[结论]污黑腐皮壳菌的培养性状和遗传多样性与地理来源有明显关系,相同省份的菌株大多被分到同一个小类群中,如吉林省、辽宁省、青海省和山东省。污黑腐皮壳菌的培养性状和遗传多样性均与地理来源有一定相关性。30个菌株中有19个菌株在2次聚类分析中被分到同一大类群中。
[Objective] The aim was to measure the gene polymorphism and the correlation degree of genetic kinship of the Valsa sordida in northern China.[Method] Thirty V.sordida strains isolated form 23 cities or counties of 9 provinces in northern China were analyzed for nutritional traits and genetic diversity.[Result] The test results showed that there was an obvious relationship between the geographical origin and the nutritional traits or genetic diversity.The cluster analysis of nutritional traits divided the V.sordida strains into the geographic groups of Northeast,Shandong,Inner Mongolia and Qinghai-Ganshu.[Conclusion] The cluster analysis of genetic diversity divided the V.sordida strains into the geographic groups of Heilongjiang,Jilin-Inner Mongolia,Shandong-Shanxi,Liaoning,Qinghai and Ganshu-Shanxi.Nineteen strains were divided into the same cluster in the nutritional traits and genetic diversity studies.
