We present the progress of the hexaploid oat consensus map which has been developed through a highly collaborative process. This map represents twelve oat populations genotyped by the 6K oat Infinium assay as well as a subset genotyped by sequencing. It resolves all 21 chromosomes of hexaploid oat and is the first consensus map to represent translocational based variants. The construction process used community-based consensus building, linkage map clustering, and most recently a phylogenetic approach in determining consensus map membership. The most current consensus map has a subset of linkage groups assigned and anchored to physical chromosomes using monosomic hybrid lines. We will present the logic and pipeline used in this process, and the current state of the consensus map. We will also discuss the successes and pitfalls that were encountered, as well as the novel approaches developed through this project.
