Rye is the only outcrossing small-grain cereal and has a large, highly repetitive diploid genome of around 8 Gb. Over the last years, we continuously advanced the molecular toolbox for rye, which now paves the way for quantitative genetics and genomics research and breeding. Deep sequencing of inbred line Lo7 at around 78x coverage provided a draft sequence for the non-repetitive portion of the rye genome. Comparative analysis of the Lo7 assembly with other grass genomes identified around 32,000 high-confidence genes. In addition, 6.5 million unique SNP positions were discovered by whole-genome sequencing of a diverse panel of 10 rye inbred lines at ~10x genome coverage. The presentation will give examples for the application of the novel tools in prediction of genomic breeding values and population genetics.

Project RYE-SELECT is funded by the German Ministry of Education and Research (grant 0315946A-E).
