  • ** Significant at P < 0.01.

  • a Bold type bins: the QTL was identified with both composite interval mapping (CIM) as well as the two-part model; nonbold type bins: QTL was identified with CIM.

  • b The marker closest to the position of the putative QTL is italicized.

  • c a, additive; d, dominance.

  • d Portion of the genotypic variance explained by a specific QTL and summing up to the total proportion Formula of the genotypic variance explained by the model including all QTL in a population–generation combination.

  • e Positive values indicate that UH400 contributed the favorable allele.

  • f Dominance ratio of the estimated dominance effect over the estimated additive effect. NA = not applicable due to nonsignificant dominance effects.

  • g For codes of populations, see Table 1.
