  • a Accessions that carry the SUN gene duplication.

  • b Accessions that carry the premature stop codon mutation in the OVATE gene.

  • c Accessions that carry the large insertion mutation in the FAS gene.

  • d Accessions that carry the mutations near the LC gene.

  • e Accessions that carry the wild-type alleles at four loci.
