Abstract: Dcpuis 1984 des introductions d'oignons sont faites en Martinique en provenance de toutes les zones tropicales. Les criteres de selection sont l'aptitude a bulbifier, une bonne conservation et la possibilite de produire des gra ines dans les condtt tons de la Martinique. Au totaI, en 1984, 93 varietes ont ete introdu ites. A la fin de la conservation, nous en avons retenu 41, soit 44%. Des graines ont ete obtenues sur 14 varietes soit 39% du nombre de porte-graines mis en place, ou 151. des varietes introduites. Elles proviennent d'israel (2), des Etats-Unis (3), du Bresil (2), d'Afrique (8). E'lles feront l'objet d'une selection massale per se pendant deux cycles de culture avant d'etre utilisees dans un programme d'amelioration. ----- Onions from various tropical and subtropical regions were tested in Martinique during 1984. The criteria used for selection were good bulbing ability, good storage and ability to set seeds under Martinquan conditions. In all, 93 varieties were introduced, of which 44% were selected. Seeds were obtained from 15 varieties when bulbs were replanted after 45 days cold treatment at 7 to 11 degrees Centigrade. Origins of these varieties were: Israel, 2; United States, 3; Brazil, 2; Africa, 8. Further improvement will be made by two cycles of mass selection followed by a breeding programme.
