Fig. 2. Frequency distribution of grain DON content and head blight rating (1 to 9 scale with 1 = healthy and 9 = >95% of all spikelets per plot diseased) for A x B (a), D x I (b), and E x F (c) winter rye F₃–line populations after inoculation with Fusarium culmorum averaged across four environments. Arrows mark the parental values (LSD_5% = least significant difference at the 0.05 probability level).
