Mohanraj, D. | Padmanaban, P. | Karunakaran M.,

A phytotoxin produced by the sugarcane red rot fungus, Colletotrichum falcatum Went. was partially purified and its effects studied on sugarcane callus development, plantlet differentiation and shoot growth in tissue culture. The findings indicate that all the above attributes were markedly reduced by the fungal toxin. Potential for the possible use of the toxin to produce red rot resistant sugarcane genotypes by pathogen toxin induced somaclonal variation is examined.
