a Scanning of the seed coat color QTL (SC) in a B. napus RIL population. b The seed color locus was detected on chromosome A09 in the RIL population. Positional cloning narrowed the SC locus to a 1.09-Mbp region between SWU-SNP02 and SWU-SNP10. c The SC locus was detected on chromosome A09 in the F2:3 and BC3F2 populations. Positional cloning narrowed the SC locus to a 79.76-kbp region between SWU-InDel03 and SWU-InDel04. The orange rectangle indicates the candidate gene. d Structure of the BnA09MYB47a alleles from black-seeded ZY821 and yellow-seeded GH06 of B. napus. The light-blue rectangles represent the exons, and the numbers inside each rectangle represent its size (bp). The green rectangle represents the inserted fragment, and the numbers inside the rectangle represent its size.
