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

Frontiers 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 ...

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

Journal 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

International 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)

Scientific 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 ...

In vitro gynogenesis in red beet (Beta vulgaris L.): effects of ovule culture conditions

Acta Societatis Botanicorum Poloniae, 2014
In this paper the influence of factors affecting gynogenic response of red beet ovules is discussed. The ovule response frequencies were the highest in the following conditions: N6 (Chu 1975) mineral salts, 0.5 mg/l IAA, 0.2 mg/l BA, 27 or 32oC.
