The Institute for Research in Tropical Agriculture (IRAT) is the Food Crops Department of CIRAD (French Center for International Cooperation in Development-Oriented Agricultural Research). The CIRAD-IRAT research project on hybrid rice was developed in three phases, starting in Montpellier, France, in 1981. From 1984 to 1989, the project was conducted in Goiania, Brazil, in collaboration with EMBRAPA/CNPAF. During this time, the basic knowledge and genetic materials necessary for organizing a breeding project on hybrid rice varieties were developed. Since 1990, CIRAD/IRAT has been conducting its own project, with the aim of selecting hybrid rice varieties for irrigated conditions in tropical countries of South America and in countries under a Mediterranean-type climate. The breeding research activities are carried out in France, principally in French Guyana, South America. Cytoplasmic male sterility is used. Trials on gametocides are also being conducted with private chemical companies. The Anther Culture Laboratory of IRAT in Guadaloupe, French West Indies, is participating in the project. The biotechnology laboratories of IRAT in Montpellier and Nottingham University (UK) are undertaking sterile cytoplasm transfer through protoplast fusion and plant regeneration. Medium-and long-term recurrent selection is ongoing. The first tests of seed production and agronomic evaluation are now being conducted in French Guyana and in the Rhone Delta near the Mediterranean. Yield tests are planned for 1993 in these areas and other tropical and Mediterranean countries. For research activities, seed production, distribution, and marketing, CIRAD/IRAT is looking for private partners
