A collection of 129 common bean landraces was evaluated for 8 agronomic traits to display the degree of variations of these germplasm resources.A total of 35 variations were detected with an average of 4.375 variations per phenotypic trait.Two clusters consisted of accessions of Andean and Mesoamerican origin,existed in Chinese common bean accessions.The average PIC was 0.5638.The dominant accessions were Mesoamerican genepool type.The genetic diversity level was higher in the Andean group compared to the Mesoamerican group.The accessions with introgression from Mesoamerican to the Andean group could be useful as bridge varieties for common bean breeding.
