Development and mapping of a public reference set of SSR markers in <i>Lolium perenne</i> L.

Abstract

Abstract We report on the characterization and mapping of 76 simple sequence repeat (SSR) markers for Lolium perenne . These markers are publicly available or obtained either from genomic libraries enriched for SSR motifs or L. perenne expressed sequence tag (EST) clones. Four L. perenne mapping populations were used to map the SSR markers. A consensus linkage map of the four mapping populations containing 65 of the SSR markers is presented, together with primer information and a quality score indicating the usefulness of the SSR marker in different populations. The SSR markers identified all seven L. perenne linkage groups.
