Multiple QTL model logarithm of the odds (LOD) profile plots for: (A) maximal quantum efficiency of PSII in the dark-adapted state, Fv/Fm; (B) fast relaxing non-photochemical quenching, NPQfast; and (C) slow relaxing non-photochemical quenching, NPQslow. Multivariate LOD profiles here are a measure (log scale) of association between marker genotype and phenotype. The significance threshold based on 10 000 permutations is given by the dashed lines.
