^aThe model mean (u), and gene additive (a) and international (i) effects were estimated based on Eq (2), and the subscripts 1–4 indicate the SD1-2, 7-1, 7-2, and 12 loci, respectively

^bA positive (negative) estimate (Est.) indicates that substituting a dormancy-enhancing with a dormancy-reducing allele promoted (reduced) germination. Effects not significant (ns) are not listed
