Abstract
           The association of peroxidase activity and isozyme pattern with smut resistance in sugarcane was studied. Co 440 (immune), HQ 409 (intermediate resistant), two immune, and two highly susceptible progenies of the two varieties, one resistant control, CAC 57 – 13, and one susceptible control Phil 56 – 226, comprise the eight clones investigated.
​      Peroxidase activity was found not to differ significantly among the clones. No significant correlation was observed between peroxidase activity of healthy tissue and healthy part of infected tissue and percent field infection.

        Infected tissues showed alteration in their isozyme pattern as compared to that of healthy tissues; there was evident increase in peroxidase activity in some isozyme and a decrease in others. However, among the various clones, the isozyme pattern did not show distinct features to differentiate immune/resistant from susceptible clones.
           The results indicate that peroxidase may not be involved in smut resistance of sugarcane and hence, may not be used as an index for such resistance.
