Technical Abstract: Searching for molecular genetic diversity using molecular markers can be expensive. It would be a benefit to maximize opportunities to resolve diversity. Two groups of soybean accessions from central China were selected randomly, or were pre-selected based on maximal isoenzyme diversity. The two groups of accessions were assayed for genetic diversity yusing RFLP techniques. The accessions, one selected based on isoenzyme diversity, had a greater than eight-fold increase in range of diversity (P > 0.001). This study demonstrates that isoenzyme diversity can be used to predict diversity at the RFLP level.
