The objective of our study was to know the differences in expression of total protein, total phenol, peroxidase and polyphenoloxidase activities in self-defense in plant tissues against rice blast diseases. The activities of these compounds were studied in different genotypes of rice (Oryza sativa L.) Ngoba, Bhalum-1, Lampnah and IET 7614 with varying degrees of susceptibility to Magnaporthe grisea. Observation was taken after two successive days interval up to 15 days repeatedly (eight times) and the data was subjected to repeated measure analysis. Gradual declination was observed for total protein, whereas total phenol, peroxidase and polyphenoloxidase activity has shown increasing trend. Rice genotypes have shown considerable difference in expression which was well-correlated with the degrees of resistance in specificity of pathogen. Univariate test for between and within subject factors were calculated and found to be significant (P<0.001). Since sphericity assumption was violated, MANOVA test was also done and significant difference among characters and genotypes were observed in due course of time.
