Disseminated infection = 0.326***(early trypsin) + 0.076R2 = 12.6%
Disseminated infection = 0.316***(B18.621) + 0.057R2 = 16.0%
Disseminated infection = 0.312***(B18.366) + 0.046R2 = 13.9%
Disseminated infection = 0.347***(late trypsin) + 0.107R2 = 17.7%
Disseminated infection = 0.337***(early trypsin) + 0.323***(B18.621) – 0.236R2 = 29.6%

  • a The F-statistics and P values represent a partial F-statistic for the general linear model where F = [(SSER – SSEF)/(d.f.R – d.f.F)]/(SSEF/d.f.F). SSE, error sum of squares; d.f., error degrees of freedom; F, model with all genotypes; R, model with one genotype. HO is rejected when Fc > F (α = 0.05, d.f.R – d.f.F, d.f.F).
