摘　　要：高粱是全球干旱半干旱地区的重要粮食作物,对干旱半干旱地区的粮食安全、边际土地利用和膳食结构调整等具有重要意义。我国自1958年第一代粒用杂交高粱问世至今,为适应机械化收获、降低人工成本,培育的粒用杂交高粱株高经历了高秆、中秆、中矮秆及矮秆的变化过程,在近20年完成了中国粒用杂交高粱的绿色革命。本文总结了中国粒用高粱矮化育种发起的原因、历程与现状,展示出我国近60年高粱品种株高不断降低与产量不断提升的变化趋势。汇总了我国粒用高粱绿色革命过程中所创制的重要种质,通过亲缘关系分析得知我国恢复系矮源来自中国地方品种三尺三,不育系因利用国外种质Tx3197A、Tx3197B较多,其矮源可追溯至Tx3197B。综述了在高粱绿色革命中发挥重要作用的高粱矮化基因dw1、dw2和dw3的克隆、变异位点、矮化机理,以及前人在发掘新的株高QTL方面作出的贡献。高粱矮化机理不同于水稻、小麦的赤霉素(GA)调控系统。dw1通过调控油菜素内酯系统(BR)缩短节间的长度从而降低株高,dw2和dw3分别编码KIPK蛋白激酶和生长素外排转运蛋白(ABCB1),调节生长素(IAA)的运输,从而缩短节间的长度进而降低株高。dw1、dw2和dw3矮化基因在降低株高的同时对成熟期、穗长、穗粒重、叶面积等其他性状产生多效影响。利用分子标记和测序技术分析dw1、dw2和dw3矮化基因在骨干不育系、恢复系中的分布和应用情况,发现我国高粱恢复系中应用较多的矮化基因只有dw3,dw1、dw2与dw3所形成的dw1dw3、dw2dw3组合在不育系中应用较多。探讨了我国高粱绿色革命存在的问题及解决途径,期望为进一步提升中国粒用杂交高粱绿色革命进程,培育产量和抗逆性有重大突破的新种质、新品种提供指导。Sorghum is the main food crop in arid and semi-arid regions of the world,which is of great significance to food security,marginal land use and dietary structure in arid and semi-arid regions.Since the first generation of grain hybrid sorghum was introduced in China in 1958,in order to adapt to mechanized harvesting and reduce labor costs,the plant height of cultivated hybrid sorghum has experienced the change process of high stalk,middle stalk,middle dwarf and dwarf.the green revolution of Chinese grain hybrid sorghum has been completed in the past two decades.This paper summarizes the reasons,history and current situation of grain sorghum dwarfing breeding in China.It shows the trend of decreasing plant height and increasing yield of sorghum varieties in China in the past 60 years.The important germplasms created in the process of green revolution of grain sorghum in China were listed.Through the analysis of genetic relationship,it was found that the dwarf source of restorer line in China came from Chinese local variety Sanchisan,and the dwarf source was traced back to Tx3197B due to the utilization of foreign germplasm Tx3197 A,Tx3197 B.The cloning,variation sites,dwarfing mechanism of sorghum dwarf genes dw1,dw2 and dw3,which play an important role in the green revolution of sorghum,and the contributions of predecessors in exploring new plant height QTLs were reviewed.The dwarfing mechanism of sorghum was different from that of gibberellin regulation system(GA) in rice and wheat.dw1 reduced plant height by regulating the brassinosteroid system(BR) to shorten the length of internodes.dw2 and dw3 encode KIPK protein kinase and auxin efflux transporter(ABCB1),respectively,which regulate the transport of auxin(IAA) to shorten the length of internodes and reduce plant height.The dwarfing genes of dw1,dw2 and dw3 had multiple effects on maturity,spike length,spike grain weight,leaf area while reducing plant height.The distribution and application of dw1,dw2 and dw3 dwarf genes in backbone sterile lines and restorer
