The technology of maize haploid breeding has the advantages of shortening the breeding cycle and improving distant hybridization incompatibility. It is widely used in maize breeding research units and enterprises. Maize haploid breeding technology, transgenic breeding technology and molecular marker-assisted breeding technology constitute three major technologies of modern maize breeding. The core of haploid breeding is to use parthenogenetic induction lines to induce haploids, and then to double to form DH lines, providing a material basis for the configuration of hybrid combinations. China started late in the application of this technology, but has developed rapidly.This article reviews the research progress on maize haploid breeding in China in three aspects of selection, the induction mechanism of parthenogenetic induction lines, selection of induction lines, and haploid identification methods, aiming at providing reference for researchers in this direction.
