The aim of this research was to study the effect of multicollinearity in cluster analysis of common bean cultivars (Phaseolus vulgaris L.) based on productive, phenologic and morphologic traits, comparing the standard obtained in the presence and absence of multicollinearity. Thus, it was planned two data sets, each with ten individuals and nine variables, to demonstrate the effect of different scales and measures of multicollinearity in the cluster. Thirteen common bean cultivars were evaluated in nine experiments conducted in Santa Maria, in Rio Grande do Sul State, Brazil (latitude 29°42'S, longitude 53°49'W and altitude 95m) in the agricultural years from 2000/2001 to 2004/2005. The following characters were evaluated in the experiments: grain yield, number of pods per plant, number of seeds per pod, weight of 100 grains, plants final population , number of days of the emergency to flowering, number of days of the emergency to harvest, height of first pod insertion, height of the final pod insertion and degree of the down. Standart cluster of common bean cultivars based on productive, phenologic and morphologic traits, differ in the presence and absence of multicollinearity. The effect of multicollinearity must be controlled to provide standards to appropriate cluster.
