About the project
Oats hold a significant place in Norwegian agriculture, representing about 25 percent of all grain cultivation in the country. The value of oats, both as feed and directly for human consumption, is substantial. As food, oats are particularly valuable due to their excellent dietary effects and broad composition of nutrients. Oats are a robust grain that can tolerate variations in nutrient availability, structure, and pH, and they are very valuable as a preceding crop for wheat. Fusarium in oats creates mycotoxins in the grain, which are harmful to humans and animals and reduce the sprout ability of the seeds. The goal is to quickly develop oat varieties with good resistance to Fusarium and mycotoxins (fungal toxins). Unlike wheat and barley, there are no known effective resistance genes against Fusarium and mycotoxins in oats, and we have limited understanding of the processes that lead to infection and resistance.
Research tasks:
- Building a core collection (‘oat base’) and conducting systematic searches for better resistance sources against Fusarium in materials within and outside the current Nordic gene pool.
- Implementing NIR analyses as a selection basis for mycotoxin resistance by using calibrations developed in ongoing projects.
- Utilizing acquired knowledge about phenotyping and genetic information and tools for precision breeding with DNA-based methods.
- Coordinate and search for resistance. The tasks here are to systematize information, search known and unknown collections, and select candidates for a core collection for further mapping.
- Further develop and use rapid methods for DON. Testing and further developing calibrations for NIR.
- Genotyping and molecular marker work to establish a platform for genomic selection. Work on developing rapid methods for use in breeding work.
