An Overview of Haploid and Double Haploid Production Methods in Wheat

Abstract

For about a century, researchers have been working on haploidy approach. Progressively, they discovered the importance and usefulness of haploids in various research fields. On the other hand, it is suggested that climate change impacts on crop production, especially wheat, requires rapid and efficient methods of plant breeding to produce new cultivars with a sufficient level of biotic and abiotic tolerance to avoid significant production loss. Haploid plants are the source for producing homozygous pure lines and genetic variability for breeding programs. It reduces the time for producing pure and stable forms of new recombination by half in plant breeding. Furthermore, haploids are source for exclusive male plants generation, induction of mutations, stress resistance and tolerance cultivars, cytogenetic studies, and doubled haploid crops. This review presents a brief overview of the haploid wheat production methods and previous successful experiments on producing haploid wheat.
