摘  要：
[目的]筛选低耗水量、高水分利用率的玉米品种组合。[方法]在抗旱防雨棚内的盆栽试验中,设置正常供水和中度干旱胁迫两种水分处理,对10个玉米杂交组合的生物产量、耗水量、水分利用率3项指标进行研究。[结果]在两种土壤水分处理下,10个玉米杂交组合在3项指标上存在显著或极显著的差异,449×交51和交51×18599的生物产量较高;449×交51和S11×411的耗水量较高,18599×S11、411×449、S11×交51的耗水量较低;交51×18599的生物产量的水分利用率最高,其次为411×449和交51×411。综合3项指标,交51×18599表现最好,在两种土壤水分处理下生物产量分别为204.45、191.90 g/株,耗水量分别为22.57、19.88 kg/株,水分利用率分别为9.04、9.29 g/kg。[结论]交51×18599是高产、耗水量中等、水分利用率高的杂交组合。

摘  要：
[Objective] The studies aimed to screen maize hybridized combinations with low water-consumption and high water use efficiency(WUE).[Method] In pot experiments conducted in an anti-drought and rain-proof shelter,two water treatments including normal water supply and middle drought stress were designed to study the 3 indexes of biomass,water consumption and WUE of 10 maize hybridized combinations.[Result] There was significant difference or extremely significant difference on 3 indexes among 10 maize hybridized combinations in 2 soil water treatments,among which,the biomasses of 449×cross 51 and cross 51×18599 were higher,the water consumption of 449×cross 51 and S11×411 were higher,the water consumption of 18599×S11,411×449 and S11×cross 51 were lower,WUE of biomass of cross 51×18599 was the highest,the second were that of 411×449 and cross 51×411.Comprehensive analysis on 3 indexes showed that the performance of cross51×18599 was the best.In 2 soil water treatments,its biomasses were 204.45 and 191.90 g/plant,resp.,its water consumptions were 22.57 and 19.88 kg/plant,resp.and its WUEs were 9.04 and 9.29 g/kg resp.[Conclusion] The cross51×18599 was the hybridized combination with high yield,middle water consumption and high WUE.
