| description | The use of open pollinated varieties adapted to specific environments represents an alternative to hybrid cultivars for producers in marginal areas for whom the high cost of state-of-the-art hybrid cultivars complicates their adoption. Despite the greater yield potential of maize hybrids, open pollinated varieties can be advantageous due to its adaptation to marginal environments, yield stability, lower seed prices, and mainly because it enables the producers to obtain their own seed. Two open pollinated maize varieties were developed by recurrent selection for their adaptation to the semi-arid region of Córdoba province. The varieties obtained were compared with commercial hybrids during three years in field trials and they showed good agronomic performance in grain yield and related characteristics, grain quality and resistance to prevalent diseases. |

Despite the greater yield potential of maize hybrids, open pollinated varieties can be advantageous due to its adaptation to marginal environments, yield stability, lower seed prices, and mainly because it enables the producers to obtain their own seed.

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.
