On 12 January, 2010, the International Wheat Genome Sequencing Consortium (IWGSC) organized a workshop to develop and discuss protocols and standards for the physical mapping of the hexaploid wheat genome and develop a consensus. In addition, the workshop surveyed the sequencing efforts undertaken within the consortium to coördinate the studies carried out in member laboratories. The goal was to ensure homogeneity in the procedures used for constructing the wheat physical maps by providing guidelines developed in expert laboratories and distributing these to the groups participating in the physical mapping and sequencing of bread wheat chromosomes under the auspice of the IWGSC.
