Remarks
A high-density genetic map was developed from an F1-derived doubled haploid population generated from a cross between cultivated barley (Hordeum vulgare) and the subspecies H. vulgare ssp. spontaneum. The map comprises 1000 loci, amplified using 536 SSR (558 loci) and 442 DArT markers. Of the SSRs, 149 markers (153 loci) were derived from barley ESTs, and seven from wheat ESTs. A high level of polymorphism (~70 %) was observed, which facilitated the mapping of 197 SSRs for which genetic assignments had not been previously reported. Comparison with a published composite map showed a high level of co-linearity and telomeric coverage on all seven chromosomes. This map provides access to previously unmapped SSRs, improved genome coverage due to the integration of DArT and EST-SSRs and overcomes locus order issues of composite maps constructed from the alignment of several genetic maps.
