This study compared the behaviour of some North African wheat varieties under salt stress, from germination to complete maturity. It revealed a depressive effect of salt on germination, growth and grain yield. This effect varied according to stress intensity and variety. Tunisian varieties showed high salt sensitivity, while Moroccan varieties were the most tolerant to this stress. These latter varieties are of interest for improvement programmes to breed varieties with high salt tolerance. They could be used to develop saline zones and/or areas where only saline water is available.
