Onion (Allium cepa L.) is worldwide an important crop species well known for its culinary use and its positive effects on human health. The crop itself has a relative small genetic basis and this hampers the development of new cultivars. This is especially true for the development of cultivars resistant to diseases and pests. Two strategies are possible to enrich the onion germplasm with novel sources of resistance, namely on the one hand sexual hybridization and subsequent backcrossing and on the other hand genetic transformation. Both strategies have been pursued with success in the past ten years in our onion genetics and breeding programme (www.plant.wur.nl/expertise/alliumresearch). In this paper the issues related to our onion hybridization research will be highlighted. Attention will be paid to Allium phylogenetics, crossability, genepool approach for alien introgression, genetic mapping and the relationship between genetic and physical maps.
