Abstract Mal de Río Cuarto (MRC) disease is a significant threat to corn production in Argentina. Sixty six hybrid combinations derived from the cross of twelve flint maize (Zea mays L) inbred lines were evaluated using a completely randomized block design with two replications. MRC disease severity grade (SG) and grain yield (GY) were the analyzed traits. Our objectives were to estimate the general (GCA) and specific (SCA) combining abilities for these traits among twelve corn inbred lines, and to identify potential heterotic relationships among them. Diallel crosses were performed and these results were compared using Griffing’s… More >
