Fig. 3

A set of 16 IR29/Pokkali and FL478/IR29 backcross lines and three RILs screened with 38 markers to define their Pokkali introgressions. The original QTL interval plots for the shoot Na–K ratio (solid line) and root Na–K ratio (dotted line) are shown on the left to indicate the location of the Saltol QTL peak. Additional markers were genotyped at the Saltol locus to more precisely define the introgression boundaries, as indicated by hash marks between RM1287 and RM7075, representing RM10694 (11 Mb), AP3206 (11.2 Mb), SKC1b (11.4 Mb), RM3412 (11.5 Mb), RM493 (12.2 Mb), RM10793 (12.5 Mb), RM10864, (14.2 Mb), and RM562 (14.6 Mb). The most common Pokkali introgressions are shown as lightly shaded boxes, the FL478 Saltol allele is shown as darkly shaded boxes, and two additional alleles derived from NIL-17 (J21) and NIL-30 (J38) are shown by striped boxes. The presence of background Pokkali introgressions is indicated by the chromosome numbers below each line (with several lines having numerous background introgressions, indicated as NUM), and the SES tolerance scores for each line are shown below each line for experiments under standard phytotron conditions (SES-1) and in growth chambers under high temperature conditions (SES-2), along with the Na–K ratio from the growth chamber experiment.
