In an attempt to develop superior Trichoderma viride isolates for improvement in chitinase Enzyme productivity, induction of mutants was applied. After application of different concentrations of Ethyl methane sulfonate (EMS) and Hydroxyl amine (HA) treatments on T.viride mutants were obtained. Trichoderma viride was determined by its physiological state so that change in genetical conditions could alter the antagonism. Hence, the genetic modification using mutagenesis offers the potential for producing improved bioprotection is likely to enhance their biocontrol. Trichoderma viride mutants grown up to six generations to check the stability on PDA and it was found variation in mutants compared to mother culture. These mutants were tested for their chitinase productivity. TvME-4 (T4), TvMH-9 (T9) and TvME-3 (T3) mutants proved to be the highest producer of chitinase enzyme, since it produced 0.64, 0.63 and 0.62 enzyme units respectively, greater than the mother culture.
