An experiment was conducted in ten locations in the regions of Azuero to determine the adaptability of 20 corn hybrids. An experimental 4 x 5 Alpha Lattice design with three repetitions was used. The analysis of variance showed highly significant differences between the different hybrids evaluated for grain yield. Of the cultivars evaluated, half exceeded the general average, with the P-4028W, P-4039 and P-4226 hybrids standing out significantly with average yields exceeding 7.60 tha^-1. This first group was followed by ADV-9779, ADV-9789, ADV-9293, ADV-9022 and SV-3243 with averages higher than seven tons. Commercial tester 30F-35 presented a yield of 6.94 tha^-1, and it was surpassed by more than 15% by the hybrids of the first group. According to the scores of the first two axes of the Biplot GGE-SReg analysis, a hybrid with greater stability was not found in all the evaluated environments, two environmental groups were found where the three hybrids of the group with the highest performance stood out for their high performance.
