Correlation analysis was carried out in seven genotypes of rice for five biochemical parameters, namely, chlorophyll content, soluble protein content, mitochondrial ATPase, succinic dehydrogenase and peroxidase activity at boot stage and grain yield per plant at maturity. Soluble protein content and mitochondrial ATPase had highly significant genotypic correlations (0.74 and 0.51) and significant phenotypic correlations (0.65 and 0.50) with grain yield per plant. It is concluded that these two biochemical parameters can be used to predict the performance of rice genotypes at boot stage.
