  1. T13, T26 and T28 correspond to growth rate phenotypes for temperatures 13 °C, 26 °C and 28 °C respectively. S34, S20 and S15 correspond to growth rate phenotypes for 34‰ salinity, 20‰ and 15‰ salinity respectively. Plasticity traits are represented by a letter followed by a number and a slash, then another letter and number. For example, S34/S20 corresponds to plasticity represented by slope of the reaction norm between the two conditions salinity 34‰ condition and salinity 20‰ condition. Surv_S15 and Surv_S20 correspond to survival trait for conditions salinity 15‰ and salinity 20‰.
  2. In the method column, MapQTL_MQM means that the QTL was detected by both MapQTL and R/qtl, RQTL_Scanone means that the QTL was only detected by R/qtl.
  3. a: estimated additive effect = (mu_A − mu_B)/2. Mu_A: the estimated mean of the distribution of the quantitative trait associated with the “a” genotype which is the genotype of the male parent. R2: the percentage of the variance explained for by the QTL. 1.5LOD_Left and 1.5LOD_Right represent left and right limits of the 1.5-LOD support interval.
