摘要：
Ditylenchus destructor is distributed widely in China and causes considerable yield losses of potatoes. Genetic diversity and variation of this species was analysed using Inter-Simple Sequence Repeats (ISSR) markers. Second-stage juveniles from 16 populations were analysed with three primer pairs and 32 fragments were considered for the analysis. Diversity levels within populations were relatively high. Cluster analysis and principle coordinate analysis grouped the majority of the nematode populations into three main clusters. At the regional level, the AMOVA indicated that about 91.4% variati...
