This symposium will summarize lessons learned from efforts to map and breed for adaptation to climate change in the USDA Triticeae Coordinated Agricultural Project (TCAP). Major research goals of this project are to develop a national breeding and genetics infrastructure to improve nitrogen use efficiency, water use efficiency, disease resistance, and low temperature tolerance in wheat and barley.  Topics will include genotyping by sequencing, exploiting the USDA National Small Grains core collections, canopy spectral reflectance, association mapping, genomic selection, and trait and genotype data management.
