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.
