Romruensukharom, S. Tragoonrung, A. Vanavichit and T. Toojinda Differential clones and random amplified polymorphic DNA markers were used to investigate the genetic diversity among twenty-four isolates of Corynespora cassiicola from rubber plantations in Thailand. According to the virulence reaction, the isolates were classified into eleven pathotypes. However, cluster analysis of RAPD data separated isolates into three groups and no correlation between different RAPD groups, pathotype or geographical region was detected. Analysis of the molecular variance revealed that 54.97% of total genetic diversity was due to variation among isolates within the regions and 45.03% came from variation between regions. The genetic differences in C. cassiicola populations provide important information for studies on disease resistance which will be useful in the choice of breeding strategies to develop resistant rubber clones. back
