In vivo HAPLOID INDUCTION AND EFFICIENCY OF TWO CHROMOSOME DUPLICATION PROTOCOLS IN TROPICAL MAIZE
Ciência e Agrotecnologia, 2015 Artificial chromosome duplication is one of the most important process in the attainment of doubled haploids in maize. This study aimed to evaluate the induction ability of the inducer line KEMS in a tropical climate and test the efficiency of the R1 ...

Genetic variability of anther donor versus spontaneous doubled haploid descendents and colchicine induced doubled haploid sweet pepper (Capsicum annuum L.) lines [PDF]
, 2001 Haploid (n) and doubled haploid (DH) plants were developed in anther culture of sweet pepper (Capsicum annuum L.). Regenerants were analyzed by flow cytometry for haploid (n = 12) and spontaneous doubled haploid (2n = 24) genomes.

Haploids and Doubled Haploids in Plant Breeding [PDF]
, 2012 Haploids are plants (sporophytes) that contain a gametic chromosome number (n). They can originate spontaneously in nature or as a result of various induction techniques. Spontaneous development of haploid plants has been known since 1922, when Blakeslee first described this phenomenon in Datura stramonium (Blakeslee et al., 1922); this was ...

Revista de la Facultad de Ciencias Agrarias, 2022 Doubled haploid onion (Allium cepa L.) plants allow the production of completely homozygous lines for a later production of hybrids. The haploid plants are normally produced using in vitro gynogenesis. The obtained haploid plantlets must be treated with
