Fig. 2. Comparison of selection methods based on SAF or random selection for identifying members of a core collection. A. Proportion of RFLP alleles detected in U.S. and world collections based on shared allele frequency (USA-SAF and World-SAF) or random selection (USA-RS and World-RS). B. Proportion of SSR alleles detected in the same collections based on shared allele frequency (USA-SAF and World-SAF) or random selection (USA-RS and World-RS).
