The spatial structure of genetic diversity among 17 populations of Cryphonectria parasitica in China was investigated using RAPD markers with the spatial autocorrelation analysis.
应用空间自相关分析方法对中国栗疫病菌 17个居群 RAPD遗传变异的空间结构进行研究，以探讨栗疫病菌居群遗传变异的分布特征及其形成机制。

A total of 113 isolates of C. parasitica from 7 populations, viz. Jiangsu, Beijing, Liaoning, Fujian, Italy, Japan and America, were amplified with 9 RAPD primers which were selected from 120 ramdom primers.
从120个随机引物中筛选出条带清晰、主带明显、重复性好的9条引物，对来自中国江苏、北京、辽宁、福建及意大利、日本、美国的7个群体共113个栗疫病菌进行RAPD分析。
-
The result revealed a lack of spatial structure of genetic variation among populations of C. parasitica indicating a fact that genetic variations of the most polymorphic loci were randomly distributed.
结果表明：中国栗疫病菌居群缺乏空间结构，绝大多数 RAPD位点变异为随机分布的空间模式，但部分位点表现出渐变、斑块和双向渐变的非随机分布模式，又显示了一定的空间结构。

Ten years wide investigation and research on the characteristics and pathogenicity of cryphonectria parasitica showed that, Cryphonectria parasitica existed widely in the distributing areas of Castanea mollissima, and that it belonged to weak parasite, only lived on the weak and dying branchs, sprouts, and soon. Cryphonectria parasitica was not main and direct death cause of Castanea mollissima, and the dead parts had no great influence on the growth of whole tree.
经过10余年对栗疫病发生特点和致病性的大量调查研究，结果表明栗疫菌在板栗分布区普遍存在，是弱寄生菌，在本地只寄生那些生长十分衰弱，即将死亡的板栗树干、苗木等，但栗疫菌的寄生不是这些部位死亡的主要和直接原因，而且它所寄生的部位局部死亡后对整株栗树的影响不大，因此，栗疫病在一般倩况下并非毁灭性病害。

Using 11 primers filtrated from total 53 primers, ISSR amplification was conducted in 220 individuals from eleven Cryphonectria parasitica subpopulations which were from four countries, and 174 polymorphic loci were detected from total 177 loci. The percentage of polymorphic loci of the total populations was 98.31%, while that at a subpopulation level averaged 20.43 %. Shannon's Information index and Nei's gene diversity of the fungus at the total populations level was 0.1769 and 0.7386, respectively.
自53个ISSR引物中筛选出11个引物，对以上四个群体的栗疫病菌11个子群体的220个菌株进行扩增，共检测到177个位点，其中多态位点为174个，多态位点百分率为98.31%。11个栗疫病菌子群体的P平均值为20.43%；群体水平的Shannon信息指数和Nei指数分别为0.1769和0.7386；各个子群体I的平均值为0.0943，h的平均值为0.0614。
