This work aimed to evaluate the performance, stability and adaptability of 20 soybean genotypes [Glycine max (L.) Merr.] in six different environments in the state of Mato Grosso. The experiments were arranged in a randomized complete block design with three replicates. The tests were carried out in the agricultural years 2004/05 and 2005/06 in the municipalities of Rondonópolis, Campo Verde and Vera. Stability and adaptability were evaluated according to the methods developed by Lin and Binns (1988) modified by Carneiro (1998) and the Centroid method (Rocha et al., 2005). Mean grain yield varied from 2372 kg ha-1 (Rondonópolis IV) to 3539 kg ha-1 (Vera) with overall mean among the environments of 2994 kg ha-1. Both methods classified the lines BCR 02 57, BCR 02 25, BCR 02 20 and the cultivars "Tabarana" and SL 88102 as having the highest productivity, adaptability and stability, indicating consistency between the methods. The following soybean lines were recommended for a wide range of environmental conditions: BCR 02 57, BCR 02 25, BCR 02 20
