AbstractMaize (Zea mays L.) is currently among the three most widely grown crops produced in the world. However, its production and yield stability is greatly affected by an array of abiotic and biotic stresses. 18 maize populations from the Algerian Saharan oasis were evaIuated under well water and water stress conditions. Water stress was started two weeks before flowering by withdrawing irrigation. Under water stress, Algerian populations exhibited a great variability and their ability to sustain yield production was superior to European and American maize. TAO was the best population followed by LOM and BTM vía the adjustment of various yield related traits. We suggested that Algerian populations can be considered as a novel source of favorable alleles for drought tolerance. However, their yield still low compared to improved populations, reason why breeding for yield will be necessary.
