Seed weight/size gene distribution map of B. napus (A genome). Column a presents the genetic linkage groups of the SJ DH population. The nomenclature of LGs follows the rules proposed by the Multinational Brassica Genome Project . Each of the LGs is represented with a vertical bar with the locus position (in cM) on the left and SSR loci names on the right. The QTLs information (peak, interval and name) of TSW were on the left-hand of the LGs. Column b lists the homologous colinear loci in B. rapa or B. oleracea. The numbers designate the physical position in B. rapa or B. oleracea chromosome with the length of amplification fragment. Column c is the Arabidopsis gene codes corresponding to the homologous loci. Column d lists the homologous genes of seed size or weight identified in B. rapa and B. oleracea. Genes that are in good fit into both Arabidopsis and B. rapa/B. oleracea physical positions are marked with asterisks. Numbers in brackets are the tandem repeat times of the tandem repeated genes.
