Abstract: [Objective] This project aims to study the optimal irrigation amount for drought resistance identification and evaluation of maize under shortage water stress in order to provide a reference for the identification of drought resistance of maize.[Method]The present 5 main varieties in Xinjiang were used as experimental materials, the effects of irrigation on yield and drought resistance of 5 varieties were studied under the condition of insufficient irrigation during the whole growth period.[Result]The results showed that the yield and drought resistance of the 5 materials showed a downward trend with the gradual decrease of total 5,283-2,283 m3/hm2.When the irrigation amount was 3,795 m3/ hm2, the yield and drought resistance of the 5 materials were the biggest.There was a significant positive correlation between the yield and grain number per ear, and grain number per row, and no correlation with 100 grain weight.[Conclusion]The total amount of water supplied by the control of irrigation was 3/4 (3,795 m3/ hm2) under normal irrigation, the yield of the five maize hybrids decreased by half, and the difference of drought resistance coefficient was maximized, which could be used for the identification and evaluation of drought resistance in maize.
