Table 5 Single nucleotide polymorphism (SNP) markers (other than Fhb1, Fhb2, and Fhb5) associated (P < 0.05) with Fusarium head blight index (FLD_IND), severity (FLD_SEV), incidence (FLD_INC), deoxynivalenol accumulation (FLD_DON), and area under disease progress curve from greenhouse evaluation (GH_AUDPC) in CDC Alsask near-isogenic lines. The numbers not in parentheses represent differences (in units for the traits) in LSmeans and the number in parentheses indicate percent disease reduction relative to susceptible allele
