An integrated map of barley was constructed based on four doubled haploid (DH) populations and three recombinant inbred line (RIL) populations. This map is an improved version of a previous map integration reported by Marcel et al (2007), including published SSR markers (Varshney et al. 2007), DArT markers (Wenzl et al 2006), EST-based markers (Stein et al 2007) and TDM markers (Potokina et al. 2008). The present integrated map contains 6,990 markers spanning 1,093 centiMorgans (cM). The integrated map was divided into 217 BINs of about 5 cM each.
