Abstract

The objective of this research was to assess grain yields in Triticum aestivum L. genotypes, under drought conditions, in the Alto Paranaíba region, Minas Gerais State, Brazil. Eleven genotypes (treatments) were assessed, in two locations (Rio Paranaíba and Patos de Minas), during two growing seasons (2007 and 2008). The experiment design was complete randomized blocks, with four repetitions. The Annicchiarico (1992) method and Lin & Binns (1988) method, modified by Carneiro (1998), were used to estimate adaptability and stability of the genotypes. The IAC 289-L4 test line and IAC 350 cultivar were superior at both locations and showed broad adaptability to the region. Under favorable conditions, the EP 011187 line showed the greatest grain yield potential. The methods used to estimate adaptability and stability showed to be easy to apply and interpret, and provided similar results.

KEY-WORDS: Triticum aestivum L.; genotype x environment interaction; water stress.
