The response of seedlings of 51 Sorghum bicolor accessions to 0, 50, 100, 150, 175, and 200 mM NaCl in solution culture was examined. Plant growth was measured as longest root lengths, maximum shoot lengths, and total plant dry weights after 14 days. Increasing NaCl concentration caused significant reductions in all three characters. Accession response to increasing NaCl also varied. The data suggest that increase in NaCl tolerance in this species through recurrent selection may be possible.
