A consensus transcript map of barley containing 1032 EST-based markers. 45 cMWG markers (Graner et al. 1991), 185 GBM markers (Thiel et al. 2003, Varshney et al. 2006) and 200 additional anchor markers (Costa et al. 2001, Graner et al. 1991, Kleinhofs et al. 1993) were integrated with new EST-based RFLP, SNP markers. Maps were constructed using Joinmap version 3.0 and Map Manager QTX; a LOD threshold of 3.0 was required for linkage mapping.
