Fig. 4.

QTL likelihood curves of LOD scores with additive effects of coexisting QTLs. Regions shown are where QTLs for the early vegetative vigour trait hypothesized to be beneficial for direct-seeded conditions were co-located with QTLs for grain yield: (A) LOD score, and (B) additive effect in the Aus276/3*IR64 population on chromosome 9. Additive effect is the effect of substituting an Aus276 allele for an IR64 allele; a positive value indicates that Aus276 contributed the allele. (See Supplementary Table S4 for additive effect values).
