Abbreviations: LOD, logarithm of odds; QTL, quantitative trait locus.
a
1A5 indicates that the 1A5 parent allele provided a higher phenotypic mean than the 1E4 parent allele. 1E4 indicates that the 1E4 parent allele provided a higher phenotypic mean than the 1A5 parent allele.
b
Data refer to within the 95% Bayes confidence interval.
