RNC: root Na+ concentration; RKC: root K+ concentration; SNC: shoot Na+ concentration; SKC: shoot K+ concentration; STR: salt tolerance rating;
Chromosome on which the QTL was located;
Variation explained by each putative QTL;
Additive effect is the effect of substituting a Jiucaiqing allele for an IR26 allele; Its positive value indicates that Jiucaiqing has the positive allele; The case of negative values is just the opposite.
