Enzyme-linked immunosorbent assay was used to compare virus contents of soybean cultivars and breeding selections inoculated with soybean mosaic virus or tobacco ringspot virus. Differences in virus content detected between cultivars did not always correspond to symptom severity. Results indicated that timing of assays, in relation to environment and plant development, and choice of leaves sampled can be critical factors in making such comparisons.
