Note: Significant QTLs are indicated in boldface. Significance levels for Tt.Ar: LRS = 16.9 at 4 weeks, 18.2 at 8 weeks, and 17.2 at 16 weeks. Significance levels for Le: LRS = 17.3 at 4 weeks. % Variation is the percentage of total trait variance explained by the QTL at each locus. CI is the width (in cM) of the 95% confidence interval and is reported only for significant QTLs. Arrows indicate direction of effect for the B6 alleles.
