Sensitivity to chloride was measured in soybean [Glycine max (L.) Merr.] cultivars Rinjani, Lokon, and Merbabu from Indonesia, and Lee from the United States. Plants were grown in solution culture to which KCl (0, 50, or 100 mol m‐3) was added gradually during days 7–14 after emergence. Excess KCl reduced growth, measured as leaf area, shoot and root biomasses, total biomass, and root/shoot ratio in 24‐day‐old plants of all cultivars. The cultivar x KCl treatment interaction was significant for all growth parameters. The order of chloride tolerance at 50 mol m‐3 Cl‐, based on the mean of all growth parameters relative to the control, was Lee>Rinjani>Lokon=Merbabu. In the 50 mol m‐3 Cl‐ treatment Lee excluded Cl‐ from the leaves, and accumulated Cl‐ in the roots; Lokon, Rinjani, and Merbabu excluded less Cl‐ from the leaves. At 100 mol m‐3 KCl, cultivar Lee lost its capacity to exclude Cl‐ from the leaves and its growth was poor. Chloride exclusion from the leaves at 100 mol m‐3 KCl was most effective in Lokon, which corresponded to the relatively good growth of this cultivar in the high KCl treatment.
