  • QTL, quantitative trait loci; Chr, chromosome; LR, likelihood ratio; DAR, days after ripening; qSD, QTL for seed dormancy.

  • a Number in the parentheses is the genetic distance of the peak located above (−) or below the marker on the Chr or Chr segment in Figure 1, Figure 3A, or Figure 4A.

  • b LR and proportion of the variance explained by the QTL (R2).

  • c Difference between the heterozygous and homozygous genotypes at the locus in arcsine-transformed percent germination for intact seeds at DAR or for caryopsis.
