中文摘要	以含有矮秆基因Rht8的冬小麦品种晋麦47与Rht13的供体Magnif M1杂交获得的含有不同矮秆基因的重组自交系ZX_(44)(Rht8)、ZX_(34)(Rht13)、ZX_(33)(Rht8+Rht13)和ZX_(16)(rht)为材料,在田间和盆栽试验条件下主要研究了矮秆基因Rht8和Rht13对不同水分状况下冬小麦水分利用效率(WUE)和产量的影响。结果表明:含有矮秆基因的三个品系ZX_(34),ZX_(44)和ZX_(33)与高秆对照系(ZX_(16))在田间和盆栽同一水分条件下的耗水量差异不显著。田间与盆栽的干旱条件下四种小麦品系的产量趋势均为ZX_(44)>ZX_(34)>ZX_(16)>ZX_(33),灌水条件下均为ZX_(34)>ZX_(44)>ZX_(33)>ZX_(16)。田间干旱条件下四种小麦品系的产量WUE为ZX_(44)>ZX_(34)>ZX_(16)>ZX_(33),灌水条件下为ZX_(44)>ZX_(34)>ZX_(33)>ZX_(16)。盆栽两种水分条件下的产量WUE趋势均为ZX_(34)>ZX_(44)>ZX_(16)>ZX_(33)。ZX_(34)品系与ZX_(44)品系的产量WUE在田间相同水分条件下、盆栽干旱条件下差异不显著,而在盆栽灌水条件下差异显著;两者的收获指数在田间和盆栽试验的干旱和灌水条件下均较高。田间相同水分处理下四种小麦品系的生物量WUE差异不显著,而盆栽相同水分条件下为ZX_(34)>ZX_(44)>ZX_(33)>ZX_(16)。综上,引入Rht8基因和Rht13基因均能明显提高产量和WUE。在配合不断选育的基础上,含有Rht13基因的冬小麦是半干旱地区小麦高WUE育种中的另一材料。
英文摘要	Water shortage is a serious problem threatening sustainable agricultural development in Northwest China,where winter wheat(Triticum aestivum L.)is the largest water-consuming crop.The objective of this study was to explore the effects of dwarfing genes on the water use efficiency(WUE)and yield of winter wheat in Yangling area.Four recombinant inbred lines(ZX_(44):Rht8;ZX_(34):Rht13;ZX_(33):Rht8+Rht13 and ZX_(16):rht)of winter wheat Jinmai 47(Rht8)and Magnif M1(Rht13)were studied in the field and pot experiments under drought and irrigation conditions.The results showed that the water consumptions of ZX_(44), ZX_(34)and ZX_(33)lines had no significant difference from that of compared with control line(ZX_(16))under the same water condition in the field and pot experiments.The yields of four wheat lines in the field experiment under drought condition decreased in the order:ZX_(44)>ZX_(34)>ZX_(16)>ZX_(33),and their yields decreased in the order:ZX_(34)>ZX_(44)>ZX_(33)>ZX_(16) in the field experiment under irrigation condition.The trend of yields of four wheat lines in the field experiment under drought and irrigation conditions was consistent with them in the pot experiment under drought and irrigation condition。The yield WUE of four wheat lines at yield level in the field experiment under drought condition decreased in the order:ZX_(44) >ZX_(34) >ZX_(16) >ZX_(33),and decreased in the order of ZX_(44)>ZX_(34)>ZX_(33)>ZX_(16) under irrigation condition。The trend of yield WUE of four wheat lines in the pot experiment under both drought and irrigation condition decreased in the order: ZX_(34)>ZX_(44)>ZX_(16)>ZX_(33)。The yield WUE of ZX_(34) line and ZX_(44) line had no significant difference under the same water condition in the field experiment and also had no significant difference under drought condition in the pot experiment,but the difference was significant under irrigation condition in the pot experiment。The harvest indices of ZX_(34) line and ZX_(44) line were higher under two water condition in the field and pot experiments。 The WUE at aboveground biomass level of four wheat lines had no significant difference under the same water condition in the field experiment。The WUE at aboveground biomass level of four wheat lines in the pot experiment under both drought and irrigation conditions decreased the order:ZX_(34)>ZX_(44)>ZX_(33)>ZX_(16)。ZX_(44) line and ZX_(34) line showed the highest yield WUE under the two water status in the field and pot experiments,respectively。Compared with the control,ZX_(44) and ZX_(34) lines presented higher WUE at aboveground biomass level under irrigation condition in the field treatment and appeared under two water status in the pot condition。In conclusion,the yield and WUE of winter wheat can be improved obviously by the introduction of Rht8gene and Rht13gene。Winter wheat carrying with Rht13 gene is another material of wheat breeding with high WUE in semi-arid areas on the basis of combining with continuous selection。
