For harnessing the full yield potential of rye, genome-based precision breeding strategies play an important role in increasing the selection efficiency and accelerating breeding processes. Recent developments in high-throughput sequencing and genotyping techniques open new possibilities for genome-wide and target-specific improvement of elite material for the development of high-yielding hybrids.

RYE-SELECT aims i) to improve the molecular toolbox for rye by developing a high-density genotyping SNP array and target-specific gene-based markers, ii) to comprehensively characterise the diversity patterns in rye breeding pools using population genetic methods as a prerequisite for the choice of appropriate breeding strategies and germplasm management, iii) to evaluate the potential of genomic selection for improving yield and yield stability in rye by adapting and developing state-of-the-art methodology, and iv) to identify and validate genomic regions involved in frost tolerance as well as yield- and quality-related traits in hybrid rye.
