1QTL region = Chromosome number and letter to define sub-region; 2: WG = 100 × (Body Weight (8 d post inoculation) – Body Weight (2 d before inoculation))/Body Weight (2 d before inoculation) (%); PC = Plasma Coloration 4 d post inoculation (log10(Optical Density at 480 nm)); inoculation;
Genome-wide probabilities thresholds are indicated as significant ** (P < 0.05) or non significant ns(P > 0.10).
