INDICADORES ECONÓMICOS PARA LA PRODUCCIÓN Y USO DE SEMILLA MEJORADA DE MAÍZ DE CALIDAD PROTEÍNICA

Economic indexes for the production and use of improved corn of quality protein (QPM) in Mexico. To promote the extensive use of quality protein corns (QPM), schemes as kg/kg of corn could be an alternative to support its spreading. The Instituto Nacional de Investigaciones Forestales, Agricolas y Pecuarias (INIFAP) in coordination with the CIMMYT, intensified research projects which allowed the releasing of commercial hybrids and QPM corn varieties. However, joint to the characteristics of each one of the materials, it is convenient to analyze the economic implications of the use of these seeds, based on their conformation as simple hybrids, trilineal, varietals, open-pollinated varieties, because there is a potential problem of its productive capacity and quality of progeny lines; which makes it necessary to analyze the efficiency of producing hybrid seeds. This work analyzes the impact of the productivity of each progenitor on the cost of producing mexican hybrids, based on the minimum productivity level. Also, an estimate is shown of the prices the farmers are willing to pay for the improved seed of quality protein varieties.
