Resistance to Fusarium langsethiae in Norwegian oats – SafeOats/TryggHavre
Over the recent decades, the Norwegian cereal industry has had major practical and financial challenges associated with the occurrence of Fusarium and mycotoxins in cereal grains. From 2011, payment reductions to farmers were implemented for oat grain lots with high levels of deoxynivalenol (DON). However, according to preliminary results by Norwegian Institute of Bioeconomy Research (NIBIO), the Norwegian University of Life Sciences (NMBU) and the Norwegian plant breeding company Graminor, certain oat varieties with generally medium or low DON contamination, may contain high levels of HT-2 and T-2-toxins (HT2+T2). These mycotoxins, formed by Fusarium langsethiae, are considerably more toxic than DON. Resistance to F. langsethiae is not included in the variety screening.
SafeOats will develop resistance screening methods in collaboration with the main Norwegian and Swedish breeding companies, thus facilitating the phase-out of susceptible germplasm. Furthermore, SafeOats will provide information whether there are varietal differences concerning the content of mycotoxins in different size fractions of oat grains, and whether seed borne inoculum might be a source of F. langsethiae infections. SafeOats will give new insight into the biology of F. langsethiae and HT2+T2 accumulation in oats, and thus facilitate the choice of relevant control measures. The results from SafeOats will benefit consumers nationally and internationally by providing tools to increase the share of high quality grain into the food and feed industry.
So far, the studies have shown that the ranking of oat varieties according to HT2+T2 content in non-included field trials resembles the ranking observed in inoculated field trials. Similar ranking of varieties has also been detected for oat seed lots. The ranking of oat varieties according to DON content is similar in non-inoculated and F. graminearum inoculated field trials. However, the ranking of oat varieties according to DON content does not resemble the ranking for HT2+T2. In oat grain samples tested so far, the levels of selected mycotoxins were reduced by approx. 50 % after removal of the small kernels. Results from germination analysis of infected seed samples does not indicate any damage from F. langsethiae to the germination capacity.
