a: Challenge 1,2: multiple-trait analysis for respectively (Na+1,Cl-1) and (Na+2, Cl-2); Na+, Cl-: multiple-trait analysis for respectively (Na+1, Na+2) and (Cl-1, Cl-2); Plasma ions: multivariate analysis for (Na+1, Na+2, Cl-1, Cl-2). b : linkage group, according to Guyomard et al. [19] and corresponding physical chromosomes (Chr) according to Phillips et al. [20]. c: maximum likelihood test value (LRT) and corresponding chromosome-wide significance level (no indication: P < 0.10; *: P < 0.05; ***: P < 0.005); *** also indicates a genome-wide significance level at P < 0.05. d: position on the consensus linkage group rebuilt with the families of the design. e: confidence interval of the position estimated with the 'drop off' method. f: mean QTL substitution effect (in phenotypic standard deviation of the trait) in the families with significant QTL effect (P < 0.05). g: nH is the total number of F1 parent segregating for the QTL (in brackets: number of parents for gill index). LR and HR indicate the line having transmitted the allele with an increasing effect on the trait. |
