Zy036 and 51070 were resequenced and blasted with B. napus genome sequence
(unpublished). Additionally, two sesame lines 28-31 and ZZM2289 (genome sequence has not been published) were also used in our research. All SNPs were chosen according to the method described in B. oleracea lines 01-88 and 02-12. The SNP primers were designed according to our primer design method.
