SNP genotypes at 15 SNP loci and the reaction of F2:3 plants with recombination events to Cercospora sojina (race 8) in a Blackhawk x PI 594891 population.
A. Genotypes at 15 SNP marker loci and the reactions of F2:3 plants with recombination events to Cercospora sojina in the population of Blackhawk x PI 594891. The 15 plants that were highlighted and underlined had the same recombination breakpoint (No. 2), but opposite phenotypes (BH = Blackhawk allele; PI = PI 594891 allele; Het = heterozygous alleles). B. Screen shot of Williams 82 genome (assembly version 1.01) (http://SoyBase.org), displaying a 72.6 kb region on chromosome 13 which contained the locus responsible for the resistance in PI 594891.
