VARIABILIDAD, HETEROSIS, LÍNEAS E HÍBRIDOS DE MAÍZ, MACOLLAJE, PROLIFICIDADAbstract
Los objetivos de este trabajo fueron: (i) evaluar la variabilidad de 15 rasgos relacionados con la plasticidad vegetativo-reproductiva en 6 líneas de maíz con diferente expresión de macollaje y prolificidad y sus 15 híbridos derivados, (ii) analizar la asociación de dichos rasgos en ambos grupos genotípicos (GG= líneas e híbridos) entre sí y con el NGP y (iii) calcular la magnitud de la heterosis, como así también la H2, las ACG y ACE y la importancia relativa de los efectos de la ACG y ACE para cada rasgo
