【 摘 要 】

At São Bento do Una locality of the Semi-arid "Agreste Region" of State of Pernambuco, Brazil, 12 maize cultivars were evaluated. The objetive of this study was to evaluate the performance of maize cultivars in this region. The experiment was carried out in randomized blocks with three replications. The evaluated parameters were: grain production, plant height, flowering, ear height and plant population. The grain production varied from 4,215 to 4,938 kg ha-1 for Double hibrid 678, and BR-201 materials, respectively. In general, the hybrid materials produced 13% more. The varieties presented yield levels of 3,777 kg ha-1 (BR-5028) to 4,412 kg ha-1 (CMS-22). The BR-201 hybrid presented 11% increase compared to CMS-22 variety in terms of grain yield.
