Genotypic correlation and path coefficient analyses of grain number and grain weight with total chlorophyll content, soluble proteins, peroxidase, mitochondrial ATPase and succinic dehydrogenase were carried out on eight rice genotypes at boot stage, flowering. 10- and 20 days after flowering. Correlation coefficients and direct and indirect effects varied with developmental stages. Soluble proteins showed significantly positive correlation with grain number per panicle at boot stage and with grain weight at flowering while mitochondrial ATPase activity indicated close association with grain number at flowering, with grain weight at 20 days after flowering.
