Doubled haploids in breeding

2003
There are many factors influencing the deployment of doubled haploidy in breeding. Strategies for exploiting doubled haploids (DHs) vary within and among species and are dependent upon available technologies. Theoretical benefits and working protocols are not however sufficient to justify DH deployment in breeding.

IN SITU DEVELOPMENT OF IN VITRO DERIVED HAPLOID AND DOUBLED HAPLOID CUCUMBER PLANTS

Acta Horticulturae, 1999
Haploid and doubled haploid plants are valuable materials for genetic and cytogenetic studies as well as for plant breeding purposes. Several in situ and in vitro methods are being studied to obtain high frequencies of haploids and doubled haploids in vitro, development patterns of which appear to be similar.

Haploids and doubled haploids in Citrus ssp.

2003
Citrus breeding is based either on conventional (hybridization, selection, mutation) or biotechnological methods, the latter employing in vitro tissue culture, regeneration from protoplasts, somatic hybridization, in vitro mutant selection, genetic transformation and haploid/doubled haploid production. All cultivated forms of Citrus spp.

HAPLOID PRODUCTION AND CHROMOSOME DOUBLING

Acta Horticulturae, 2006
In the applications of haploid plants, chromosome doubling has a major role and has been widely researched. Chromosome doubling restores fertility to plants and often results in genetically homozygous doubled haploids. In diploid and allopolyploid species these homozygous plants have the potential to become pure breeding new cultivars or the parents ...

Doubled Haploid Production in Higher Plants

2017
The use of doubled haploidy is a powerful tool in crop improvement programs and basic research. A haploid embryo or plant has the gametic chromosome number (n). When haploid cells are doubled, the resulting embryo/plant will have the somatic chromosome number (2n) and be 100% homozygous.

The Significance of Doubled Haploid Variation

1984
Doubled haploid breeding has aroused considerable interest in recent years as methods of creating doubled haploids have become more efficient. This subject has been reviewed by a number of authors (Reinert and Bajaj, 1977; Nitzsche and Wenzel, 1977; Sink and Padmanabhan, 1977; Kihara, 1979; Maheshwari et al., 1980; Hu and Shao, 1981; Kasha and ...
