Abstract
RAPD-PCRs were used to study 79 isolates of Rhizoctonia solani AG 8 representing four pectic isozyme groups [zymogram (ZG)] (ZG1-1, 1-2, 1-4 and 1-5) from various locations in southern Australia. RAPD-PCR was performed on all isolates using six primers and the relatedness of the isolates determined by generating a neighbour joining tree. All isolates were also grouped according to vegetatively compatible populations (VCPs). Within each ZG there were four to nine VCPs. These studies show that the AG 8 population contains four distinct groups that matched the four ZGs and support the concept that ZGs are distinct intraspecific groups.
