Interação genótipos-ambientes.Abstract -In order to evaluate the performance of soybean cultivars, three essays were carried out at Formoso do Araguaia, TO,Brazil, in the inter-cropping 2007 (15/05, 30/05 and 12/06). The experimental design employed was a randomized blocks with ten treatments and tree replications. The treatments were composed by ten soybean cultivar (DM Nobre, NIDERA In 7002, DM 247, DM 309, DM 339, M-SOY 8411, M-SOY 8914, M-SOY 8866, M-SOY 9350 and FT 106). In evaluating the performance of cultivars, a study was conducted of adaptability and stability by the methods of Eberhart and Russell (1966) and centroid. The average grain yield varied from 1023 kg ha -1 (15/05) to 1234 kg ha -1 (12/06), with a general average of 1142 kg ha -1 . Based on the classification obtained by the methods of Eberhart and Russell (1966) and centroid, the cultivars DM Nobre, NIDERA In 7002, M-SOY 9350 and M-SOY 8914, were promising for the cultivation under conditions of intercropping. There was agreement among the methods on the classification of genotypes.
