Genetic map and synteny between the A and the B genomes. The LGs deriving from the A genome are named from a01 to a10 and those deriving from the B genome from b01 to b11. Map distances are given in Kosambi centimorgans. Common markers between pair of homeologous LGs are underlined and connected with dashed lines. Markers placed at LOD < 4 are represented in italics, and those that amplified more than one locus on the same genome are identified by the number 1, 2 and 3. Loci showing significant segregation distortion (P < 0.05) are identified by stars following locus name. The colour and number of stars specify the direction and the intensity of the segregation distortion respectively. Blue: markers skewed toward the alleles of the cultivated parent. Red: markers skewed toward the alleles of the wild parent.
