| 摘 要： | 采用同工酶聚丙烯酰胺凝胶电泳方法分析了７个栗疫菌（Ｃｒｙｐｈｏｎｅｃｔｒｉａｐａｒａｓｉｔｉｃａ）群体的遗传结构．遗传相似性分析表明中国４个群体间相似性较好；美国群体与意大利群体相似，而且它们与日本群体的相似性优于与中国群体的相似性，表明美国的栗疫菌可能是从日本传入的．总群体的遗传差异为０．１６０，其中８１．３％由群体内的变异引起，１６．９％由群体间的差异引起．群体间的基因流动值为２．４６．

| Abstract: | The population structure of Cryphonectria parasitica was analyzed using the isozymes polyacrylamide gel electrophoresis 115 isolates were sampled from 7 populations Genetic similarity analysis showed that 4 populations in China were similar among themselves; American and Italian populations were similar to each other, and more similar to Japanese than to Chinese This result suggested that the pathogen might be introduced into America from Japan The genetic diversity of the total population was 0 160, with 83 1% attributable to diversity within populations, and 16 9% among populations The gene flow estimate between populations was 2 46 |
