Expired Plant Variety Protection (ExPVP) network diagram and distribution of segregating single-nucleotide polymorphism (SNPs). (A) Network of relationships for the ExPVP inbreds constructed using identical by state (IBS) values greater than 0.9. Each dot (inbred line) has a different color assigned based on the company where it was developed. (B) Distribution of the segregating SNPs between the three heterotic groups that form the three main clusters in the network graph.
