Adaptability and stability of maize hybrids in Sergipe and Alagoas States in biennium 2001/2002

In the biennium 2001/2002 twenty-two maize hybrids were evaluated in ten environments of Sergipe and Alagoas states in order to know the adaptability and the stability for ends of cultivares recommendation. The combined analysis of variance showed significative differences among the hybrids and the existence of genetics differences among the hybrids as a answer to the enviromental variations. The ideal material by the bissegmented model was not found in the evaluated group. It was not also found any hybrid with all necessary requirements for adaptation in the unfavorable environments. The hybrids that showed general adaptability have expressive importance for this region.
