Embrapa Milho e Sorgo or the National Maize and Sorghum Research Center is one of 39 decentralized research centers of Embrapa (Brazilian Agriculture Research Corporation) in Brazil. The mission of Embrapa-MS is to generate, adapt and transfer knowledge and bobkl.jpg (17380 Byte)technology that allies efficiency in the production and utilization of maize and sorghum to the rational utilization of natural resources; procuring competitiveness in the agriculture sector, sustainable development, and the well being of society. Embrapa-MS, since it’s inception in 1975, has had a research thrust to generate maize and sorghum production technology for the vast acid savanna or “cerrado” of Central Brazil. Genetic standards of maize germplasm for both resistance to aluminium toxicity and improved phosphorus efficiency has been identified and developed. Modern high yielding maize and sorghum hybrids and production-management technology have been developed for the “cerrado” and released for the Brazilian farmer. Embrapa-MS has a multifacit, multidisciplinary research agenda directed toward investigating the physiological and genetic mechanisms associated with the various aspects of abiotic stress tolerance in maize. The strategy is to use both improved genetic resources and production management practices to develop and improve maize production sustainability in the tropical acid savanna or “cerrado” of Brazil.  The following multidisciplinary research staff will have major participation in this project: V.M.C. Alves (Plant Nutrition), S.N. Parentoni (Plant Breeding and Molecular Biology), M.J.V. Vasconcelos (Molecular Biology), A.F.C. Bahia Fº (Soil Fertility), M.A. Lopes (Plant Breeding and Molecular Biology), E. Paiva (Molecular Biology), C. Guimarães (Molecular Biology), H.T. Prates (Chemistry) and G.V.E. Pitta (Plant Nutrition and Soil Fertility).  The project will be coordinated by R.E. Schaffert. This diverse group of scientists has been involved in the successful R&D program of Embrapa to develop cultivars and production systems for maize in the “cerrado” of Brazil over the past two decades.
