  1. aNPH, plant height under normal condition (Changping, Beijing). SPH, plant height under salt stress (Tongzhou, Beijing). PHI, plant height-based salt tolerance index. bQTLs are designated as “q” followed by trait name: “NPH” (plant height under normal field), “SPH” (plant height under salt stress) and “PHI” (plant height-based salt tolerance index), and then the chromosome number. cPhenotypic variation explained by QTL. dAdditive effect of tolerance allele
