Allelic variation of SD1-2 (A/a) in effect on germination with genotypes of SD7-1 (B/b), 7-2 (C/c), and 12 (D/d) loci. The upper- and lower-case letters indicate dormancy-enhancing (germination-reducing) and -reducing (germination-promoting) alleles at the four loci, respectively, in the background of the ‘abcd’ genotype (non-dormant control). Note that SD1-2 differed from the other three loci in that the dormancy-reducing and -enhancing alleles reduced and promoted germination, respectively, in the genotypes where the other loci fixed for the dormancy-enhancing alleles. The allelic variation of SD1-2 was exemplified by germination at 7 and 150 days of after-ripening (DAR)
