PHENO-MORPHOLOGICAL AND AGRONOMIC DIVERSITY IN A COLLECTION OF WILD AND DOMESTICATED SPECIES OF THE GENUS LUPINUS

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 (CA) and principal component analysis (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 the 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.
