The haplophase of the male gametophyte in Angiosperms represents a unique experimental system for studying many problems of plant cytogenetics. The cultivation of haploid plant cells in vitro, resp. obtaining the sporophyte with gametic chromosome number, is not only theoretically interesting but it is also of practical importance, especially in plant breeding. Androgenetic embryoids have been successfully induced in some species of four genera belonging to the family Solanaceae - Datura; Nicotiana, Atropa and Lycium. In other ca. 20 genera the proliferation of haploid cells of the male gametophyte into a callus tissue was successfully induced under in vitro conditions. In some cases the organogenesis of shoots occurred. The problems of experimental androgenesis in vitro in Angiosperms have been summarized by some authors in reviews. The presented paper summarizes the experimental results of the anther cultures of Capsicum sp. on two basal culture media with addition of morphogenetically active substances. [AS]
