Currently, in vivo haploid induction technology has been com- monly used in maize （ Zea mays L. ）. This paper briefly introduced in vivo haploid induction technologies, summarized doubling methods of maize haploids and described the significance and application of maize haploids, which provided the basis for further development of haploid breeding in maize.展开更多
