QTL mapping and validation of qGR6.2. On the left, the red line represents the region of QTLs among the BC₁F₂ population, on the right, validation of qGR6.2 among the BC₂F₂ population under 300 mM NaCl conditions. The LOD curve indicates the strength of evidence for the presence of qGR6.2 within Z604~Z605 on chromosome 6. Dashed lines show LOD thresholds of 3.0. Marker names and genetic distances are shown on the right of the chromosome. Chr., chromosome; cM, centimorgan; LOD, the likelihood of odds; PVE, phenotypic variation explained by QTL; ADD, the additive effect of substituting a WJZ allele for a Nip allele, which its negative value indicates that WJZ contains the positive allele; DOM, dominance effect
