The effects of genotype x environment interaction (GxE) on the stability and adaptability of 9 soybean (Glycine max (L.) Merrill) elite lines and one control (IAS 5) were studied in 11 locations in the States of Paraná, Rio Grande do Sul, São Paulo and Mato Grosso do Sul, during the 2000/01 and 2001/02 crop seasons. A complete randomized block design, with three replications, was used in all environments. Significant differences for the effect of genotypes, environments and interaction GxE were observed for grain yield. Statistical models followed the standard method, ecovalence, Eberhart and Russel, Cruz, Torres and Vencovsky and AMMI methodologies. Genotypes CD 97-922 and CD 98-3118 were responsive under unfavorable environments. Lines CD 97-1243, OC 95-3006, OC 95(10)-3441 and IAS 5 showed a large adaptability and desirable stability, while OC 95-2806, CD 96-437, CD 97-945 and OC 95-3152 showed good adaptability but not high stability. In spite of the similarities detected among results obtained from different methodologies, every one gave its contribution to a better understanding of the observed GxE relationshipsDownloads
