Conteúdo: | Pests can strongly affect maize yield in tropical regions. The performance of maize populations against fall armyworm resistance under different environments was evaluated and the possibility of introducing some of these populations into maize breeding programmes was determined. The trials were conducted in 3 naturally pest-infested environments in Esperanza, Argentina. The populations were evaluated for plant (PH) and ear height (EH), grain yield (Y), and fall armyworm-resistance (FAR). Significant differences among the populations were observed for Y and FAR, besides a significant genotype x environment interaction. The genotype x environment interaction for FAR could be explained by the erratic performance across the environments presented by one of the tolerant populations. Our results attested that at least one of the tested populations could be included into the maize breeding program.
