摘　　要：结合常规玉米单倍体育种技术及自身多年的实践经验,主要探讨了优化玉米单倍体育种技术流程。常规单倍体育种流程需要9年能完成,优化后单倍体育种流程需要8年能完成,可以看出优化后的流程比常规的流程品种选育进程快了1年,加快了新品种的选育速度,促进了新品种的推广和应用。The optimization procedure of maize haploid breeding technology was discussed mainly with conventional breeding technology of maize haploid and many years′corn breeding experience in the domestic and foreign.The conventional maize haploid breeding procedure can be completed in 9 years,but the optimized haploid breeding procedure can be completed in 8 years.The results showed that the breeding process of the optimized procedure was one year faster than that of the conventional procedure,which speeds up the breeding speed of new corn varieties and promotes the popularization and application of new corn varieties.
