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 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
its 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.
