Doubled Haploid (DH) is an efficient tool in plant breeding programs. This method reduces time to homozygosity. DH production has been developed and routinely used in several species but not sorghum. The objective of this review is to provide an overview of DH production and the barriers in DH production of sorghum from previous studies on three potential methods for haploid induction; androgenesis, gynogenesis, and wide hybridization. The information could be valuable in the development of DH protocol in sorghum which may be employed in genetics and molecular studies.
