Zusammenfassung:	The invention relates to a double-haploid method for sunflower plants by in situ gynogenesis characterized in that no pollen is used. The invention is based solely on castration that makes it possible to obtain an immature haploid embryo in the ovary on the plant, followed by embryo rescue. La présente invention concerne une méthode d'haplodiploïdisation de plantes de tournesol par gynogénèse in situ caractérisée par l'absence d'utilisation de pollen. L'invention repose sur la seule castration qui permet l'obtention d'un embryon haploïde immature dans l'ovaire sur la plante, suivie d'un sauvetage d'embryon.
