Genetic diversity among Croatian common bean landraces

Classification of genetic diversity in collected plant material may significantly facilitate its maintain and enhance the utilization. The objective of this study was to group common bean (Phaseolus vulgaris L.) accessions originated from different collection sites into clusters according to their morphological similarity. Nine quantitative morphological traits were scored and reduced to four principal components (PCs). Squared Euclidean Distances based on PC-scores were used as input for cluster analysis. Cluster grouping can only be partially explained by geographical origin of the accessions analyzed.
