The aim was evaluating the productive behavior of 21 genotypes of forage maize of different origins and seeing their adaptation in semi-arid areas in Soledad de Graciano Sanchez, SLP, at 22.22° north latitude and 100.85° west longitude at 1 835 masl. In temperate dry climate with an average temperature of 17.1 °C and precipitation of 362 mm. In 21 corn genotypes of different regions, the Plant Height (PHeight), Number of leaves per plant (NLeaves), Stem diameter (Diameter), Height of the first corn (EHeight), Foliar area of the corn leaf (FACL), Number of corn (NCorn), Yield of dry matter of the plant (YDMP), of leaf (YDML), of stem (YDMS) and of corn (YDMC), Relationships Leaf: Plant (RLP), Stem: Plant (RSP), Corn: Plant (RCP); Neutral Detergent Fiber (NDF) and Acid (ADF). The experimental design was completely randomized with six replications. The Tlaha2 genotype showed the highest value of PHeight with 2.5 m and EHeight with 1.4 m. Tampiqueño1 showed the highest NLeaves with 13.6. Chalqueño showed the largest diameter with 4.1 cm and the greater FACL with 775.97 cm2. Papjalb/a, AS948-2 and Gdelfin showed the highest number of corns with 1.5 pl-1 corn. Chalqueño and Tampiquelo1 showed the highest YDM values with 46 246 and 42 947 kg DM ha-1, respectively. It is concluded that there are genotypes from other regions that adapt to the dry climate of semi-arid areas and produce higher RMS and with better morphological components than other creoles and that the recommended improved varieties.
