摘　　要：通过在抗旱防雨棚内的盆栽试验,设置正常供水和中度干旱胁迫两个水分处理,对10个玉米杂交组合的生物产量、抗旱性、耗水量及水分利用效率进行了研究。试验结果表明:在不同的土壤水分处理下,10个玉米杂交组合在生物产量、抗旱性、耗水量和水分利用效率上存在着显著或极显著的差异。综合来看,交51×18599表现最好,属高产、抗旱性强、耗水量中等、水分利用效率高的杂交组合。By pot experiments under an anti-drought and rain-proof shelter, two water treatments were densigned including normal water supply and middle drought stress. It was studied to biological output, sistance, water consumption and water use efficiency drought re（WUE） of 10 maize hybridized combinations. The results showed that there was significant difference or extreme significant difference in biological output and drought resistance and water consumption and water use efficiency （WUE） of 10 maize hybridized combinations under different soil moisture treatments. Comprehensive analysis on biological output and drought resistance and water consumption and water use efficiency （WUE）,the performance of cross51× 18599 was the best. and it was hybridized combination with high yield, drought resistance well, medium water consumption and high water use efficiency （WUE）.
