  • *The significance of including an interaction term between the QTL and CYS4 after Bonferroni correction is <0.05.

  • a The maximum LOD for each unique QTL.

  • b The intersection of pleiotropic QTL intervals defined by a 1.5-drop in LOD score, preferably from an individual cross.

  • c QTL identified without covariate; all others were identified using CYS4 as a covariate.

  • d The cross in parentheses indicates in which cross a QTL showed cross-specific effects. NA indicates that the test was not applicable since cross-specific effects were not detected in either of the two combined cross analyses.
