The level of the fungal toxin deoxynivalenol (DON) in milled flour and its partitioning between flour and bran of 15 spring wheat (Triticum aestivum) lines with different levels of Fusarium head blight (FHB; mainly caused by Fusarium graminearum) resistance was investigated in Hokkaido, Japan between 2004 and 2007. The DON levels in flour (DON f ) and bran (DON b ) showed positive linear relationships with DON levels in whole kernels (DON k ) (R 2 = 0.94, n = 60, P ≤ 0.01 and R 2 = 0.93, n = 60, P ≤ 0.01, respectively). Results indicated that the DON partitioning ratio between flour and bran is primarily related to the level of DON k , and the DON level was approximately doubled in DON b and halved in DON f for any level of DON k . Only one pattern of DON partitioning supported the conventional strategy to select FHB-resistant lines.
