Dear Editor,Genome editing technologies have paved the way for exciting and novel applications in plant biotechnology.Doubled haploid (DH) technology has a significant and valuable advantage over traditional approaches in crop breeding.Unlike traditional breeding processes,which may take over eight generations to stabilize the genetic background of interest,DH allows homozygous lines to be obtained within two generations (Kelliher et al.,2017).Recently,a gene called MATRILINEAL (MTL)/ZmPLA1 has been cloned from maize mateal haploid inducer lines and found to be conserved across cereal crops (Kelliher et al.,2017;Liu et al.,2017).The gene,together with everadvancing genome editing technology,provide the potential to generate mateal haploid inducer lines among multiple cereal crops.
