Figure 4From: SNP frequency, haplotype structure and linkage disequilibrium in elite maize inbred linesNeighbor-joining trees representing acetyl-CoA C-acyltransferase haplotype relationships. Level of support for branch points is indicated in %, and branch length expressed as nucleotide differences are shown in parentheses. Genotypes correspond to those of Table 1, and color indicates major heterotic groups: stiff stalk (blue), non stiff stalk (green) and Lancaster (red).Back to article page
