SummaryThe first haploid angiosperm, a dwarf form of cotton with half the normal chromosome complement, was discovered in 1920, and in the ninety years since then such plants have been identified in many other species. They can occur either spontaneously or can be induced by modified pollination methods in vivo, or by in vitro culture of immature male or female gametophytes. Haploids represent an immediate, one-stage route to homozygous diploids and thence to F 1 hybrid production. The commercial exploitation of heterosis in such F 1 hybrids leads to the development of hybrid seed companies and subsequently to the GM revolution in agriculture. This review describes the range of techniques available for the isolation or induction of haploids and discusses their value in a range of areas, from fundamental research on mutant isolation and transformation, through to applied aspects of quantitative genetics and plant breeding. It will also focus on how molecular methods have been used recently to explore some of the underlying aspects of this fascinating developmental phenomenon.

“…Doubled haploids have been widely employed in barley breeding programs, resulting in the release of several cultivars (see Muñoz-Amatriaín et al, 2008). Androgenesis-based DH-technique was used to produce barley varieties better suited to Peruvian highlands where barley is extensively grown as a food crop (Gomez-Pando et al, 2009).…”

The usefulness of haploid plants in basic research in cytogenetics, genetics, evolution, and practical plant breeding is well known. Haploid plants provide an efficient research tool for studies on induced mutagenesis and genetic transformation. They also help elucidate the genetic control of chromosome pairing inherently present in allopolyploids such as bread wheat, durum wheat, and oats. Genetic control of chromosome pairing in haploid nuclei has helped in assessing intergenomic relationships. By analyzing the degree and specificity of chromosome pairing in the Ph1‐ and ph1b‐euhaploids (2n = 3x = 21; ABD), we demonstrated that the A and D genomes of wheat are more closely related to each other than either one is to the B genome. It is significant that the totipotent nature of a haploid cell is being exploited in several facets of biological research. In addition to its numerous applications in basic research, the haploidy approach provides an efficient means of producing truly homozygous lines, thereby accelerating the breeding process. Wheat cultivars developed from doubled haploids (DHs) have been released for cultivation in Canada, China, Europe, and Brazil. General characteristics and classification of haploids derived from diploid and polyploid species are provided in this article. Methods of extracting haploids of polyploid wheats are described, and applications of haploidy in basic and applied research are discussed.

“…in this manner by doubling chromosomes in haploid plants it is possible to obtain genetically stable homozygous lines in a short time thereby providing a method for speeding up and increasing the selection efficiency. Such homozygous DH plants have been used in breeding programmes for production of pure lines and new highly adaptive and productive varieties (1,4,8,15,16,18,20,21,23,24,35,41,48). A number of studies (2,19,37,45,53,55) also reported that the obtained by the in vitro anther culture techniques haploids and Dh plants are an appropriate system for genetic manipulations, gene mapping and mutant line selection.…”
