Polyacrylamide gel electrophoresis for undigested (a, c) and digested (b, d) WT-dCAPS1 marker products. Lanes 1–13 represent thirteen tolerant accessions, and lanes 14–26 represent thirteen sensitive accessions in a natural population. Lane 1 and lane 14 refer to ‘Nannong Xuefeng’ and ‘Monalisa’, respectively. Lanes a–m represent 13 tolerant F1 lines. Lanes n–z represent 13 sensitive F1 lines, which were derived from ‘Nannong Xuefeng’ × ‘Monalisa’. M, molecular weight size marker with a 20 bp ladder
