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.

Oat Doubled Haploids Following Maize Pollination

2017
Doubled haploids (DHs) are an important tool for the accelerated production of new crop varieties. In oat, DHs were first produced by pollinating oat florets with maize pollen. The resultant embryos spontaneously eliminate the maize chromosomes leaving a haploid complement of oat chromosomes.

A method of line development using doubled haploids: the single doubled haploid descent recurrent selection

Theoretical and Applied Genetics, 1988
Different methods of line development using doubled haploids in recurrent selection are presented. They are divided into two types: recurrent selection with progeny testing and recurrent selection on the phenotype of lines. It is shown that one of the best methods of line development is based on “single doubled haploid descent recurrent selection ...

Rice Doubled Haploids and Breeding

2008
Cell- and tissue culture methods in combination with conventional breeding process were suitable way to produce new varieties. These applications gave new breeding alternatives to release competitive genotypes in comparison with traditional ones. To the breeding of 'Risabell' (1997) DH lines were produced via anther culture from F 2 population of a ...

Doubled haploid mutant production

2003
The use of haploid systems for mutant induction and selection has been listed among the most important applications of haploid technologies, since their development (Kasha, 1974). Haploid tissue can facilitate the generation of genetic variation and its identification.

Doubled haploids for locating polygenes

Canadian Journal of Genetics and Cytology, 1983
A biometrical method, making use of one or two marker genes, was proposed for use in doubled-haploid populations to locate polygenes. A polygene, if located between two closely linked marker loci, can be detected in a doubled-haploid population derived from a cross of two diploid inbred 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.

Doubled Haploid Breeding in Cereals

2015
Doubled haploid (DH) production has become an important tool in plant breeding largely due to its capacity to produce completely homozygous plants in one generation. Not only are traits fixed for selection but the multiple generations of inbreeding required using traditional breeding methods are circumvented.
