Fig. 1. Simple sequence repeats (SSR) linkage map and putative quantitative trait loci (QTLs) for seed dormancy. White and black circles represent putative region of QTLs for seed dormancy detected in the three-way cross and F2 populations, respectively. Black bars represent two epitatic loci. Loci with significant segregation distortion from the expected segregation ratio (P < 0.05) are marked with I or J, where the frequency of indica allele and that of japonica allele increased, respectively.
