The present work took place in the central and northern regions of the state of Campeche, Mexico. The grain yield was evaluated in a total of 46 materials, comprising 30 of white grain and 16 of yellow grain. The crop was supplied to a greater extent with rainwater from the months of July to November. The sowing was in trials designed to evaluate grain yield and technology validation lots established for demonstration purposes. To integrate a genetic material into this study, it was a fundamental requirement that it had at least four evaluations considering different locations or years. As a result of the above, it was determined that there are 27 hybrids of white grain and 14 of yellow grain, which constitute options for the producer with which it is possible to obtain yields of 4.1 to 6.0 t⋅ha⁻¹ and that can make corn a profitable crop under the current conditions of technology application. Of the white grain hybrids, the group formed by SB-309, DK-395, DK-393, DAS-2382, SP-500, DK-390, P4082W, 9209W, P3966W, SORENTO, JC-25, LUCINO, and 9401W was considered as the high productivity stratum, whose average yield is 5.1 to 5.9 t⋅ha⁻¹. Similarly, in the yellow grain hybrids, the group formed 9107Y, SP-525A, 2B688, DK-7500, P4226A, IMPACT and DK-7088, was considered as the high productivity stratum, whose average yield fluctuated from 5.0 to 5.9 t⋅ha⁻¹.
