Abstract: Haploid induction is an important method for obtaining homozygous lines in Compositae. Haploids have been induced in 13 Compoditae species, and 9 species was successfully obtained. The pathways to obtain haploid plants in Compositae include anther culture, isolated microspore culture, in vitro gynogenesis culture, intergeneric hybridization and induction of haploid by irradiated pollen. The factors affecting in vitro induction and regeneration of haploids including developmental period of the explant, pretreatment, medium and its component, and culture condition were discussed in the paper. The methods of haploid induction in Compositae were compared. This review also proposed some problems in the Compositae haploid research, and provided reasonable suggestions.

Key words: anther culture, Compositae, haploid, in vitro gynogenesis culture, microspore culture
