摘　　要：玉米育种的关键在于自交系的选拔。优良自交系选育的质量和速度决定了组配杂交种的水平和表现。传统的自交系选育方法所需周期长、规模大、费时费力,已不能适应现代市场对于新品种的需求。目前,最好的方法是双单倍体育种方法,此方法通过单倍体诱导系可以诱导产生10%左右的母本单倍体种子,经过加倍处理,即可获得100%纯合的自交系。杂交诱导单倍体育种方法的根基是诱导系的创制与诱导率提升。The key for hybrid maize breeding is to select for superior maize inbred lines.The speed and quali-ty in developing maize inbred lines are helpful to elevate the level of combining ability or hybrid performance.Con-ventional maize breeding needs longer breeding cycle,bigger scale,higher cost,and labor intensive,which is notadapted to the market demand for better hybrids in a shorter time frame.The best and quickest solution is the dou-ble haploid breeding method.In maize,there is a tool named haploid inducer line that can genetically producearound 10%maternal haploid seeds.These haploids can be doubled to form 100%genetic pure inbred lines throughchromosome doubling procedure with doubling agents.It points that the creation of haploid inducer line and the in-crease of the induction rate is the root of DH technology development.
