Doubled haploid production is a valuable biotechnology that can accelerate the breeding of new wheat varieties by several years through the one-step creation of 100% homozygous plants. The technology also plays important role in studying the genetic control of traits in wheat, in marker-assisted selection, in genomics and in genetic engineering. In this paper, recent advances in androgenesis and gynogenesis techniques, emphasizing predominantly the in vitro culture phase, as well as the emerging innovative approaches in researching and producing wheat doubled haploids are reviewed. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based genome editing, that allows targeted mutagenesis and gene targeting, is being tested extensively as a powerful and precise tool to induce doubled haploids in wheat. The review provides the reader with recent examples of gene modifications in wheat to induce haploidy.
