GrainGenes maps	GrainGenes is a genetic database for Triticeae, Avena, and Saccharum supported by United States Department of Agriculture, Department of Energy and National Science Foundation
Steptoe x Morex BIN maps	Barley Genomics lab (Prof. Andris Kleinhofs) at the Washington State University, Pullman, WA, USA
Barley integrated SNP map	Integrated SNP map produced from 333 genic SNP markers segregating in Steptoe x Morex, Oregon Wolfe Barley Dominant x Recessive and Lina x HS92 populations (Rostoks et al. 2006). Map is also available from the Barley SNP DB (Scottish Crop Research Institute Bioinformatics web site)
Barley integrated DArT map	Integrated barley linkage map based on segragation of 2085 DArT markers in 10 mapping populations (Wenzl et al. 2006)
Barley integrated transcript map	Integrated barley linkage map based on SNP, SSR and RFLP markers segregating in Steptoe x Morex, Igri x Franka and Oregon Wolfe Barley Dominant x Recessive populations (Stein et al. 2007)
Barley integrated high-throughput SNP genotyping map	Integrated barley linkage map based on segregation of >1100 SNP markers in Steptoe x Morex, Oregon Wolfe Barley Dominant x Recessive and Barke x Morex populations. SNP genotyping was carried out using high-throughput Illumina GoldenGate platform. Map has been reported by Rostoks et al. 2006, but a dedicated publication will follow.
