Crop breeding aims to generate pure inbred lines with multiple desired traits. Doubled haploid (DH) and genome editing using CRISPR/Cas9 are two powerful game-changing technologies in crop breeding. However, both of them still fall short in rapid generation of pure elite inbred lines with integrated favorable traits. We report here the development of a Haploid-Inducer Mediated Genome Editing approach (IMGE for short), which utilizes a maize haploid inducer (HI) line carrying a CRISPR/Cas9 cassette targeting for a desired agronomic trait to pollinate an elite maize inbred line, and to generate genome edited haploids in the elite maize background. Homozygous pure DH lines with the desired trait improvement could be generated within two generations, thus bypassing the lengthy procedure of repeated crossing and backcrossing used in conventional breeding for integrating a desirable trait into elite commercial backgrounds. We envisage that this technology could be widely used to accelerate crop breeding.
