Table 3.
Positions of quantitative trait loci (QTL) in backcross (BC1S1) families of a Lactuca sativa cv. Dynamite × Lactuca serriola (Eys) cross using composite interval mapping. Quantitative trait loci results of the recombinant inbred lines population from a L. sativa cv. Salinas × L. serriola (UC96US23) cross are described in detail in Hartman et al. (2012; but see Table S2 for SPSS QTL). A positive additive effect indicates that crop genomic background (L. sativa) causes higher trait values, whereas a negative additive effect indicates that the wild genomic background (L. serriola) causes higher values. QTL on the same line have peak values within 5 cm
