a SES scores, b chlorophyll content, c shoot, and d root Na–K ratio of a set of 39 BC₃F₅ IR29/Pokkali lines analyzed with SSRs between 11 and 15 Mb on chromosome 1 (RM1287, RM10694, RM8094, RM10793, RM10864, and RM7075) to assign categories based on having a homozygous Pokkali allele (20 lines), heterozygous allele (four lines), or IR29 allele (15 lines) at the Saltol locus. Trait means with standard errors (vertical bars) are shown for each genotypic category along with the IR29 (sensitive) and FL478 (tolerant) checks across the four traits tested at the seedling stage using a hydroponic system at an EC of 12 dS m⁻¹.
