title: Molecular variation among Chinese and global winter faba bean germplasm.
abstract: A sample of winter faba bean germplasm from China was compared with germplasm from outside China, using AFLP analyses. Both sets of germplasm were obtained from the National Genebank of China, Institute of Crop Sciences (ICS), Chinese Academy of Agricultural Sciences, Beijing, China. A sample of 39 winter type accessions from outside of China and 204 Chinese landraces and varieties (201 winter types and 3 spring types) were characterized with 10 AFLP primers. These detected 266 polymorphic bands. The Chinese germplasm was clearly separated from the rest of the world in principal component analysis and clustering analysis, with the spring types from China showing the greatest separation. Yunnan germplasm, both landraces and commercial varieties, showed the greatest separation among the germplasm of Chinese winter faba bean provinces. The landraces/varieties from Anhui, Zhejiang, Sichuan, Jianxi, Guizhou and Fujian provinces clustered in a central group.
