A comparison of common markers mapped between the ‘Heritage’ linkage map in this investigation and the ‘Latham’ × ‘Glen Moy’ (L×GM) linkage maps of Graham et al. (2006, 2011) [,]. The version of the L×GM map that was used for comparison of each linkage group was based on the number of common markers mapped to the ‘Heritage’ map and is designated after the LG name by the year of publication. Linkage group nomenclature on the ‘Heritage’ map follows the revisions proposed by Bushakra et al. (2012) . Genetic distances are given in centi-Morgans.
