Figure 2.

Genetic map of Mi-9 and key S. arcanum recombinants. A map of the short arm of chromosome 6 is shown on the left. Mi-1 homologs RH1, RH2, RH3, and RH4 are from S. arcanum accession LA2157, while SH1, SH2, and SH3 are from accession LA392. The region in S. arcanum from accession LA2157 is represented by vertical thick bar, from accession LA397 is represented by vertical thin bar, and heterozygous region is represented by vertical multiple line bar. In recombinants, junctions between regions are depicted as midway between flanking markers.
