Ha. Yang et al., CHARACTERIZATION OF CEREAL BARE PATCH ISOLATES OF RHIZOCTONIA-SOLANI BY RANDOM AMPLIFIED POLYMORPHIC DNA ANALYSIS, Plant Pathology, 44(5), 1995, pp. 811-818
RAPD-PCR was used to characterize isolates of Rhizoctonia solani from
bare patches in cereal and pasture crops at two locations in Western A
ustralia, Newdegate and Esperance. All of the isolates belonged to ana
stomosis group 8, pectic zymogram group 1-1 or 2. The pectic zymogram
assignment could be confirmed by RAPD-PCR. There was no difference in
RAPD-PCR pattern between highly virulent and weakly virulent isolates
at Newdegate, or between isolates from different patches at Newdegate.
The Newdegate isolates were identical to isolates from Esperance, and
to isolates from various locations in South Australia.
