Cytospora chrysosperma%RAPD%colony characteristics
Totally 30 strains of Cytospora chrysosperma causing poplar canker,derived from ten provinces in China were classified into two clusters based on the cluster analysis of colony characteristics. The first cluster was separated into the geographic groups of Xinjiang,Beijing-Northeast and Shandong and the second cluster was separated into the geographic groups of Inner Mongolia and Sichuan-Gansu-Shaanxi-Qinghai. In ferm of RAPD makers, the 30 strains were also separated into two clusters by the cluster analysis. The first cluster was classified into the geographic groups of Beijing, Xinjiang,Liaoning,Gansu-Qinghai and Shandong-Heilongjian-Jilin-Shaanxi. The second cluster was separated into the geographic groups of Inner Mongolia and Sichuan. The results showed a clear relationship between the geographical origin and the colony characteristics or genetic diversity of the pathogenic fungus.
