Cross-fertilization behaviour of some white flowering varieties of Vicia faba

Summary Applying a special design for maximalization of cross-fertilization and using flower colour as a marker, considerable differences in the percentage of cross-fertilization between white flowering Vicia faba varieties were observed. Part of these differences were due to differences in beginning of flowering in white and coloured varieties, part of them proves to be independent of this and, therefore appear to be characteristic for the variety. Interaction between mother and father varieties was absent.
