Doubled haploid production from Spanish onion (Allium cepa L.) germplasm: embryogenesis induction, plant regeneration and chromosome doubling

open access: yesFrontiers in Plant Science, 2015
The use of doubled haploids in onion breeding is limited due to the low gynogenesis efficiency of this species. Gynogenesis capacity from Spanish germplasm, including the sweet cultivar Fuentes de Ebro, the highly pungent landrace BGHZ1354 and the two ...

Increasing the genetic uniformity of bighead carp [Aristichthys nobilis (Richardson)] by means of spontaneous diploidization of gynogenetically activated eggs [PDF]

open access: yes, 2008
Three groups of gynogenetic diploid bighead carp were successfully obtained by means of artificial gynogenesis. The activation rates of gynogenesis varied from 75.9% to 98.8%, and the frequency of spontaneous diploidization was around 0.4%.

The effects of sugars and growth regulators on embryo- and callusogenesis in isolated ovules culture of beetroot, Beta vulgaris L. [PDF]

open access: yesCaspian Journal of Environmental Sciences, 2021
Haploid techniques have risen interest among researchers and breeders as they significantly reduce the time of creating pure lines in breeding programs, especially for biennial vegetable crops.

In Vitro Gynogenesis in Leek (Allium ampeloprasum L.)

open access: yes, 2021
Leek (A. ampeloprasum L.) is an economically important vegetable crop from Alliaceae family. It is a non-bulb forming biennial species grown for its pseudostem and leaves. Leek is a tetraploid with one of the largest genomes known among cultivated plant species.

Haploid Induction via In vitro Gynogenesis in Tomato (Solanum lycopersicum L.)

open access: yesJournal of Integrative Agriculture, 2014
In order to determine the potential for haploid induction via in vitro gynogenesis in tomato, the ovules and protoplasts of embryo sacs from the hybrids Zhongza 101 and Zhongza 105 were cultured.

Effect of Media on Gynogenesis Induction in Leek (allium ampeloprasum L.) Breeding Materials

open access: yesInternational Journal of Secondary Metabolite, 2014
Leek (Allium ampeloprasum L.) is one of the economically important members of the genus Allium (family:Alliaceae). It is a self-compatible, outbreeding, tetraploid (2n=4X= 32) crop species that is very difficult to improve through traditional breeding ...

Diploid Gynogenesis Induced by Heat Shock after Activation with UV-Irradiated Sperm in Rainbow Trout (Oncorhynchus Mykiss)

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
Gynogenesis is a technique used to generate diploid individuals with genetic material exclusively of maternal origin. In this study we test the hypothesis that heat shock treatment of rainbow trout eggs, activated with UV irradiated sperms, leads to the ...
