Proceedings of the Fifth Asian Regional Maize Workshop Hanoi, Ho Chi Minh City, Vietnam. November 15-20, 1993. Organized by the Ministry of Agriculture and Food Industries of the Soc. Rep. of Vietnam and the CIMMYT-Asian Regional Maize Program.
The International Maize and Wheat Improvement Center (CIMMYT) is an internationally funded, nonprofit scientific research and training organization. Headquartered in Mexico, the Center is engaged in a worldwide research program for maize, wheat and triticale, with emphasis on food production in developing countries. It is one of 13 nonprofit international agricultural research and training centers supported by the consultative Group on International Agricultural Research (CGIAR) , which is sponsored by the Food and Agriculture Organization (FAO) of the United Nations, the International Bank for Reconstruction and Development (WOrld Bank), and the United Nations Development Program (UNDP). The CGIAR consists of 40 donor countries, international and regional organizations, and private foundations. CIMMYT receives support through the CGIAR from a number of sources, including the international aid agencies of Australia, Austria, Brazil, Canada, China, Denmark, France, India, Ireland, Italy, Japan, Mexico, the Netherlands, Norway, the Philippines, Saudi Arabia, Spain, SWitzerland, the United Kingdom, the USA, and West Germany and from the European Economic Commission, Ford Foundation, Inter-American Development Bank, International Development Research Center, OPEC Fund for International Development, Rockefeller Foundation, UNDP, and World Bank. Responsibility for this publication rests solely with CIMMYT. COrrect citation: Granados, G., C. De Leon and J. E. Lothrop, eds. 1993. Proc. Fifth Asian Regional Maize WOrkshop.
