Schematic model of development of InDel marker used to detect 57-bp deletion mutation across exon 4 and intron 4 ofBrFLC2. (a) Insertion and deletion identified in B. rapa ssp. olerferious. Del, deletion; In, insertion. Amplified region used to detect deletion mutation covered part of exon 4, intron 4, and part of exon 5. (b) Amplified fragments. In and Del represent insertion allele and deletion allele, respectively, followed by fragment size (in base pairs). Nine accessions (1–9) are listed in same order as in Table 2 .
