摘　　要：有两套遗传体系决定矮生玉米的节间长度,即多基因矮生体系和单基因矮生体系。矮生玉米自交系的选育方法主要有系谱法、回交法和聚合选择法。矮生玉米自交系的利用主要有“矮秆×矮秆”“和矮秆×高秆”两种模式,其中“矮秆×高秆”将是今后相当长时期内矮生玉米自交系利用的主要模式。The internode lengths of dwarf maize depend on polygenic and monogenic systems. Pedigree method, backcross method and convergent cross selection are used widely in dwarf maize breeding. Two models of dwarf x dwarf and dwarf × high-stem inbred line are used in dwarf maize breeding. But the model of dwarf maize utilization is mainly dwarf × high-stem inbred line in future.
