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.
