8th INTERNATIONAL WHEAT CONFERENCE

1%-72% and from 3%-55% in Germany and Canada, respectively. In 2009, range was
10.7-46.2% in Germany and 3.4-55.1% in Canada. DON level in Canada ranged from
0.3 ppm- 41.3 ppm, while overall mean was 9 ppm in 2008. The resistant host cultivars
were stable in performance across the environments. In conclusion, significant progress
has been made in Ontario, Canada winter wheat development in the past ten years with
respect to FHB resistance. We will present data on FHB index and DON levels from
the Ontario Winter Wheat Performance and Orthogonal trials, after inoculation with F.
graminearum, and discuss the relationships between these traits.
