%X Several genetic breeding programs contributed to the development of soybean cultivars with highyield and adapted to different Brazilian edaphoclimatic conditions. However, the continuous progressof genetic breeding of this specie depends on the genetic variability and application of geneticparameters informations which helps a more efficient selection process.There are many multivariatedtechnical approaches to study the variability among soybean groups, such as dissimilarity measures,cluster analysis, principal components and canonical variables. The heritability estimation, geneticgain and genetic correlations are important parameters which permit the breeder to choose thebest improvement strategy.
