The use of imported seeds of hard-yellow maize hybrids becomes increasingly limited for small and medium farmers, owing to increased costs. In the farm of the Universidad Nacional Agraria La Molina and in the Don German farm in Cañete, two simple hybrids were evaluated with the objective of estimate the agronomic and economic differences between their F1 and F2, the years 2011-2012. In both locations, the agronomic characteristics evaluated were higher in F1 for both hybrids. All the economic indicators evaluated showed that the sowing of the hybrids in La Molina and in Cañete, it was advisable to use F1 seed. The grain yield and profitability of the F2 of the Dekalb 7088 hybrid in La Molina was reduced by 29.16% and 37.33% respectively, relative to those of its F1; While in Cañete these reductions were 37.73% and 47.79% respectively. For the case of the hybrid NK 254, reductions in grain yield and profitability of F2 compared to F1 in Cañete, were 31.24% and 34.29%, respectively. Risks, sensitivity analysis and probabilities of high costs and minimum yields were lower for F1 compared to F2.
