N2  - Rigidoporus lignosus, widespread in equatorial and humid tropical zones, is the most dangerous root parasite on rubber tree. Twenty isolates collected from a wide range of geographical origins were studied to evaluate intraspecific variability of this fungus using native polyacrylamide gel electrophoresis technique.  Soluble protein banding patterns obtained by isoelectric focusing and isozyme profiles showed a high level of intraspecific polymorphism in R. lignosus.  Factor analysis of soluble protein banding patterns unequivocally separated several groups of isolates according to their geographical origins. Enzyme profile comparisons also conformed to biogeographical patterns, with greatest isozyme polymorphisms in the Far-East than in Africa.  However, geographical distances by themselves were not sufficient to explain all the intraspecific variability
