Constructing a dense genetic linkage map and mapping QTL for the traits of flower development in Brassica carinata

An integrated dense linkage map of Brassica carinata (BBCC) was constructed in a doubled haploid population based on DArT-SeqTM markers. A total of 4,031 markers corresponding to 1,366 unique loci were mapped including 639 bins, covering a genetic distance of 2,048 cM. We identified 136 blocks and islands conserved in Brassicaceae, which showed a feature of hexaploidisation representing the suggested ancestral crucifer karyotype.
