Forage Crop Genetics

The implemented Forage Crop Genetics group mainly aims at developing genetic and genomic tools that can assist plant breeding. Recent technical advancements have enabled to characterize the genetic diversity that is available for plant breeding at high resolution and allow more efficient selection based on single DNA markers or high-density genome profiles. This “molecular breeding” approach, a non-GMO strategy to increase breeding progress in crop species, is a sustainable way to improve plant productivity.

As a specific example, our efforts to characterize genetic mechanisms such as self-incompatibility or cytoplasmic male sterility increased our understanding of how to use these mechanisms as breeding tools to efficiently control pollination in forage crops. Management of these genetic mechanisms in practical breeding by means of molecular markers will help pave the way towards the implementation of more efficient hybrid breeding schemes in forage grass species. On a long-term perspective, our research will contribute to sustainable feed and food production on both the local and global level.
