The effects of irrigation (40-45, 60-65 and 80-85% of the available soil moisture) on the yield, yield components and water use efficiency of wheat cultivars Sids 1, Gemmeiza 7, Sakha 8, Gemmeiza 9, Sakha 93, Giza 168, Gemmeiza 5 and Giza 170 were determined in a field experiment conducted in Egypt in 2001-03. Drought stress resulted in a significant reduction in the grain and straw yield of the cultivars, although the reduction in straw yield was not significant. The number of spikes, number of grains per spike, grain weight per spike, 1000-grain weight increased with increasing irrigation, with Gemmeiza 7 recording the highest values for the parameters measured except number of spikes. Water consumptive use increased with increasing water stress, with Gemmeixa 9 recording the highest water consumption use. Water use efficiency increased with decreasing irrigation, with Gemmeiza 7 recording the highest water use efficiency Sakha 93 was the most drought tolerant cultivar tested.
