^a: linkage groups according to Guyomard et al. [19] and corresponding physical chromosomes (Chr) according to Phillips et al. [20].
^b: maximum likelihood test value (LRT) and corresponding chromosome-wide significance level (no indication: P < 0.10; *: P < 0.05; **: P < 0.01).
^c: position on the consensus linkage group rebuilt with the families of the design.
^d: confidence interval of the position estimated with the 'drop off' method.
^e: QTL substitution effect (in phenotypic standard deviation of the trait). Mean, min and max refer respectively to the mean, minimum and maximum QTL effects recorded among families with significant QTL effect at P < 0.05.
^f: n_H is the number of F1 parent segregating for the QTL. LR and HR indicate the line having transmitted the allele with an increasing effect on the trait.
