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