Variations in the productive performance of genotypes due to genotype x environment interactions assessed in different environments have been detected during selection processes. The stronger the interaction, the more erratic the cultivar performance. Adaptability and stability analyses reduce the effects of genotype x environment interactions, improving genotypic performance differentiation. Lin & Binns (Lin & Binns, 1988, Canadian Journal of Plant Science, 68:193-98) propose a methodology for the analysis of the adaptability and stability of genotypes, using the Pi index. The Pi accumulates the behavior of a tested genotype with the genotype having the best performance in each environments. Thus, the smaller the cultivar Pi magnitude, the greater its adaptability and stability. As the Pi statistics has variance properties, it weighs the behavior deviations of cultivars efficiently, is easily interpreted, attractive for plant breeders. In a study carried out during the last four cropping seasons (1999/00,2000/01,2001/02 and 2002/03), in the Northern Brazilian "Cerrados", the genotypic behaviors of eight soybean cultivars developed by Embrapa were evaluated. The cultivar BRS-219 (Boa Vista) (Pi = 10.308; productivity= 3.058 kg/ha; early maturity) showed the best adaptability among the genotypes studied. BRS Sambaíba (Pi = 37.401; productivity = 2.897 kg/ha; medium maturity), BRS Candeia (Pi = 40.900; productivity = 2.968 kg/ha; medium maturity), and BRS Tracajá (Pi = 43.662; productivity= 2.892 kg/ha; early maturity) also reveled higher ability in low latitude regions. BRS-165 (Seridó RCH) (Pi = 72.145; productivity= 2.948 kg/ha; late maturity) was the late maturity cultivar with the best performance, showing the best relative average stability. BRS Juçara (Pi = 423.232; productivity = 2.404kg/ha; medium maturity) and BRS Babaçu (Pi = 220.771; productivity= 2.644 kg/ha; late maturity) showed the highest Pi values, thus representing the least adaptable cultivars to the region under study. BRS-164 (Pati) (Pi = 154.616; productivity = 2.754 kg/ha; early maturity) showed a high Pi; however, this cultivar is recommended for fertile soils together with the use of modern production technologies. In general, the region's hydric regime, characterized by concentration of rains in a short period of time, contributed to the higher productivity level of the early and medium maturity soybean cultivars.
