LOD threshold was 3.51 calculated on 1000 permutations basis at the significance level of $\mathrm{\alpha }=\mathrm{0.0.5}$. ^aRC/ABS, reaction centers involved in $Q_A^{-}$ reduction per Photosystem II antenna chlorophyll; ET/(TR-ET), electron transport beyond $Q_A^{-}$; PI_ABS, performance index (potential) for energy conservation from photons absorbed by PSII to the reduction of intersystem electron acceptors. ^bPhenotypic variation explained by the QTL. ^cAdditive effect-negative sign of the effect means that the favorable allele comes from B73.
