Abstract

Haploids are individuals possessing a single set of chromosomes of the species (. n), which is the number of chromosomes in a gamete. Therefore, a haploid plant is considered in the sporofitic stage however, it has the gametic number of chromosomes typical of its species. The first reports on haploids are from the 1920s. According to reports, the first haploid angiosperm species identified was a dwarf cotton plant. The next reports in the scientific literature were with Datura stramonium, Nicotiana tabacum, and Triticum compactum humboldtii. Today, there are several methods to obtain haploids and double haploids (DH), such as inducing-haploid gene, anther and microspore culture and interspecific crosses, among others. © 2014 Elsevier Inc.
