In this study we analyzed the genetic diversities of Qinghai’s faba bean (Vicia faba L.) germplasms based on AFLP techniques. The results showed that the number of effective alleles in landraces, foreign germplasms and released cultivar are 1.065 5±0.126 3, 1.063 4±0.143 0, and 1.065 9±0.165 1, while the Shannon’s information index are 0.095 4±0.144 9, 0.084 3±0.151 8, 0.074 2±0.167 9, respectively. The ratio of effective allele of landrace is the lowest (73.73%), while its ploy-ratio is the highest (44.51%). Whereas the ratio of effective allele of released cultivars is the highest (90.39%), while its ploy-ratio is the lowest (17.92%). The genetic distance is relatively bigger in the landraces and smaller in the foreign germplasms. Genetic structure analysis revealed that the 149 faba bean germplasms in Qinghai can be divided into 7 groups. In this study we have selected 40 germplasms as core germplasm collection which would represent more than 80% genetic information of the tested 149 germplsams based on the genetic diversity and Nei\'s gene diversity.It is obvious that the core germplasm collection germplasms might be used as parent materials for hybrid breeding in faba bean breeding program.
