Conteúdo: 	Forty-three soybean cultivars were tested in the 1983 International Soybean Variety Evaluation Experiment. The experimental sites were divided Experiment. The experimental sites were divided into thirteen environmental zones which were defined by latitude and altitude. Three sets of cultivars were sent out: group A to the tropics; group B, subtropics; and group C, temperate regions. The performance characteristics: yield, days to flowering, days to maturity, plant height, height to the first pod, seed size, and several other characteristics are presented for all locations and summarized over all the locations where a given cultivar was grown. The relative stability of the performance of a cultivar over a wide range of environments was determined. It was found that the relative stability estimates for cultivars were quite consistent in different groups. Davis was very stable while SIATSA 194 was unstable. The association of the various characteristics was studied by calculating the correlation coefficients among the characteristics measured at each location. Yield was positively correlated with number of plants harvested and seed weight and negatively associated with seed quality. These and other relationships can help plant breeders determine if it may be difficult to get the combination of characters desired in new cultivars. Days to maturity is one of the most important characteristics in determining whether a cultivar is well adapted to a given location. The association of this characteristic with the response..
