El empleo de variedades de maíz de libre polinización adaptadas a ambientes específicos representa una alternativa para productores de zonas marginales para los cuales es problemática la adopción de cultivares híbridos de última generación por su alto costo. A pesar del mayor potencial de rendimiento de los cultivares híbridos, las variedades de polinización libre pueden ser ventajosas por su adaptación, estabilidad, menor costo y la posibilidad de obtener semilla propia. Dos poblaciones de maíz de libre polinización fueron desarrolladas mediante métodos de selección recurrente para adaptación a la zona semiárida del centro de la provincia de Córdoba. Las variedades obtenidas se compararon con cultivares híbridos comerciales durante tres años en experimentos a campo y presentaron buenas características agronómicas relativas a los componentes del rendimiento, resistencia a enfermedades prevalentes, calidad y rendimiento en grano.
