| Summary, etc |
La presente investigación se realizó en condiciones experimentales con el objetivo de evaluar la estabilidad del rendimiento y la expresión de heterosis en cruzas simples y triples de maíz (Zea mays L.), así como sus implicaciones en la producción de semilla comercial. La metodología empleada consistió en el establecimiento de ensayos comparativos bajo un diseño experimental adecuado, analizando variables agronómicas y productivas mediante métodos estadísticos de estabilidad y estimación de heterosis. Los resultados evidenciaron diferencias significativas entre tipos de cruzas, destacando las cruzas simples por mayor heterosis y rendimiento, mientras que las cruzas triples mostraron mayor estabilidad, aportando criterios técnicos para la producción eficiente de semilla comercial. |
