Haploids are plants with a gametophytic chromosome number and doubled haploids are
haploids that have undergone chromosome duplication. The production of haploids and …

The interest of fruit breeders in haploids and doubled haploids (DH), lies in the possibility of
shortening the time needed to produce homozygous lines compared to conventional …

Forty-four protocols of doubled haploid production (DH) are presented in this Manual. They
are related to at least 33 plant species, not counting protocols on production of DH from …

Background Plant tissue cultures have the potential to reprogram the development of
microspores from normal gametophytic to sporophytic pathway resulting in the formation of …

Based on a protocol for microspore culture in apple (Malus domestica Borkh.), the embryo
induction phase has been improved with regard to pretreatment of microspores for initiation …

Haploid and doubled haploid (DH) production provides a particularly attractive
biotechnological tool in breeding of perennial crop species, such as fruit trees. Haploids …

An improvement of the protocol for haploid induction through anther culture of Citrus
clementina Hort. ex Tan. cv. Nules was achieved following the evaluation of a number of the …

Polyploidy appears to have played a limited role in citrus germplasm evolution. However,
today, ploidy manipulation is an important component of citrus breeding strategies. For …

In this chapter, we present a list of species (and few interspecific hybrids) where haploids
and/or doubled haploids have been published, including the method by which they were …

Regenerants from anther culture of Citrus clementina Hort. ex Tan. cvv. Nules, SRA 63, and
Monreal were obtained in different experiments from 1994 to 2002. Genetic analysis of 37 …
