Abstract: In order to develop the potential water use efficiency (WUE) of maize (Zea mays L.) and achieve high yield and high efficiency in production, maize hybrids bred and popularized in China were used as materials, the high efficiency was analyzed according to yield WUE in mature time under changing and less rainfall conditions. The results showed that there were significant WUE variations among different genotypes. WUE of maize hybrids had abundant types. Analysis of variance for different characters of WUE showed that the difference of characters related to WUE among these materials was significant. WUE of different maize hybrids could be realized by different characters. Simple correlation analysis and partial correlation analysis results showed that row number, kernels per row and weight of 100-kernel were significantly related to WUE. Therefore, maize hybrids should be applied according to local agricultural production condition. The related characters to WUE of maize should be stressed in maize breeding process.
