aTP, training population; ADV, F4:7 advanced FHB trial; ARE, F4:8 elite FHB trial.
bBroad-sense heritability for FHB_TP18, ADV18, ADV19, ARE19, and ARE20 calculated using entry-mean based heritability. Narrow-sense heritability was calculated for FHB_TP19.
cDON was recorded in μg g–1, whereas FDK and SEV were recorded in percentage.
dHeading date was recorded as day of year after 1st of January, when 50% of the heads were emerged from the flag leaf.
ePlant height was recorded in inches from the surface of the soil to the tip of the head minus awns if present, but reported in centimeters here.
