Abstract: Based on 8 years' pot and field experiments，water use efficiency (WUE) of winter wheat was evaluated on genotypes，planting densities，and water supply. The results showed that when water supply amount varied in a larger range，negative linear correlation existed between total water use(ET)and WUE.

Key words: Winter wheat, Water use efficiency, Total water use, Grain yield
