  1. aThe physical positions of seven SNPs, which were also presented as arrowheads on the top line in Fig. 2a.
  2. bThe genotype of Dw1 reported by Quinby et al.21.
  3. cThe SNP in Dw1 that forms the premature stop codon in bmr-6 (b highlighted with bold font), while SIL-05 contains its WT allele (S highlighted with italics).
  4. dSNPs of SIL-05 and bmr-05 presented as S and b, respectively (highlighted with italic and bold font, respectively).
  5. eOriginal milo such as ‘Tall White Sooner Milo’ (SA1170) carrying Dw1, and Standard milo contain the same haplotype of ‘Dwarf White Milo’ with one exception, the SNP in Dw1.
  6. fThe 2-dwarf type ‘Dwarf White Milo’ carrying dw1 contains the same haplotype as bmr-6.
  7. gAll 3- or 4-dwarf cultivars contain the same haplotype as bmr-6 or ‘Dwarf White Milo’.
  8. hOther cultivars, including Kafir and Hegari, contain the same haplotype as SIL-05.
