K/Na ratios have been determined in the leaves of salt-treated plants of 14 disomic substitution lines in which each of the D-genome chromosomes replaces the homoeologous A- or B-genome chromosome in the tetraploid wheat variety Langdon (AABB genome). Aneuploid lines of hexaploid bread wheat (cv Chinese Spring) having a reduced or an enhanced complement of chromosome 4D have also been examined. These investigations show that the gene(s) determining K/Na ratios in the leaves of wheat plants grown in the presence of salt is located on the long arm of chromosome 4D.
