Abstract :The aim of this study was evaluated variability in collection of 20 genotypes represented eight domesticated and wild species of genus Lupinus. Analyses were made using multi-dimensional assessment based on twenty simultaneously considered characters from three years fields experiment . The cluster analysis insert ignore into journalissuearticles values(CA); and principal component analysis insert ignore into journalissuearticles values(PCA); were performed for illustrated diversity among investigated genotypes. The first three principal components contributed for 75.8% of the overall multi-trait variability in the means of all analyzed characters. The first principal component was found to account for 38.4% of the variability. The phenological phases and the height of a plant had t he greatest contribution to this particular component. The second principal component accounted for 23.3% of the diversity regarding the number of pods from a lateral stem and emergence. On the other hand, the number of pods from the main stem and 1000-seed weight constituted traits the strongest linked with the third principal component, which accounted for 14.1% of the diversity. The obtained results will be helpful to define a strategy in the future lupin breeding programs.
