Abstract : The hexaploid 2 (Gossypium hirsutum L. x G. australe F. Muell.) was backcrossed to G. hirsutum to produce the pentaploid G. hirsutum x G, australe and seven alien monosomic addition lines of Gossypium australe on G. hirsutum. The different hybrids produced were characterized morphologically, cytogenetically and using genomic in situ hybridization and eighty-six Simple Sequence Repeat (SSR) markers. The analysis of their progenies allowed to quantify the frequency of genetic material exchanges between the supernumerary alien chromosome and G. hirsutum. The seven monosomic addition lines obtained constitute valuable genetic stocks to carry out fundamental and applied investigations. (Résumé d'auteur)
