Portugués. The maize crop stands out against the national agricultural production, which promotes the frequent emergence of new cultivars and demand for evaluations regarding local performance. In this context, the objective of this work was to evaluate super early maize cultivars as development characteristics and potential of use in the Cerrado region of Goiás during the first crop. Eighteen genotypes of super early maize were evaluated, among varieties and hybrids, in an experiment with a randomized block design, conducted in Goianésia-GO. General development variables were evaluated, as well as variables related to characteristics for green corn, grain corn and silage. The data were analyzed by analyzes of variance and cluster. The genotypes showed different performance for the evaluated characteristics. The cultivar BAL280PRO presented better performance as the characteristics for the production of green corn. Genotypes 2B587PW and 30A37PW showed higher grain yield. While for the silage characteristics, the simple hybrid BAL280PRO and the triple hybrid CSP-SEMPREX043 presented greater potential. For cultivation indication of these genotypes should be checked their performance in years and different places, for obtain stability information.
