Table 3 Means and standard errors for field incidence (FLD_INC), field severity (FLD_SEV), field FHB index (FLD_IND), and deoxynivalenol (FLD_DON) accumulation in gene classes and check lines for CDC Alsask and CDC Go near-isogenic lines. The data is combined over 6 environments. Means within each column for each population followed by same letter are not statistically significantly different according to Fisher’s least significant difference (LSD) at P = 0.05

From: Genetic factors affecting Fusarium head blight resistance improvement from introgression of exotic Sumai 3 alleles (including Fhb1, Fhb2, and Fhb5) in hard red spring wheat
