Linkage map construction for the Cranbrook x Halberd mapping population

This report presents details of the construction of a linkage map for the Cranbrook x Halberd mapping population. This population consists of 166 doubled haploid (DH) lines. Full details concerning this population can be found in Kammholz et al. (2001). A total of 165 lines were genotyped using a 90K SNP chip containing gene-associated SNPs that provided dense coverage of the wheat genome (Wang et al., 2014). These markers were combined with three phenological markers which were available for this population. There were a total of 16231 markers available for linkage map construction. The SNP marker names reported hereafter correspond to their index number on the Illumina iSelect 90K SNP array. The consensus map of Wang et al. (2014) was used as a reference map during construction.
