Abstract:
Damping-off, caused by Pythium aphanidermatum is one of the most serious disease in nursery of bidi tobacco. However, the incidence and severity of the disease differ from one location to other, one geographical area to other and even differs from country and region wise. The random amplified polymorphic DNA (RAPD) banding patterns of seventeen isolates of Pythium aphanidermatum generated by 5 random oligonucleotides showed a very high level of variation, allowing these isolates separated into two groups. This result revealed that two isolates genetically distinct from all other fifteen isolates.
