Box plots of the best linear unbiased estimators (BLUEs) of Fusarium head blight (FHB), stripe rust (Yr), leaf rust (Lr), leaf spot (Ls), and common bunt (bunt) in three spring wheat populations evaluated in field conditions. All diseases were rated on a 1 to 9 scale, except the FHB index in percentage. Both ACG and PAC are recombinant inbred lines derived from Attila × CDC Go and Peace × Carberry, respectively, whereas BVC is an association mapping panel of diverse spring wheat cultivars and lines. The environments on the x-axis start with a prefix for each site (Cres: Creston station in British Columbia; Edm: the University of Alberta South Campus in Edmonton; Elle: the Ellerslie research station in Edmonton; Leth: Lethbridge Research and Development Centre; Carm: the University of Manitoba Research Farm in Carman; Mord: Morden Research and Development Centre), followed by the year of the experiment.
