Abstract: | Summary The genetic variation in pickling and slicing cucumbers (C. sativus L.) seems insufficient to enable the breeder to solve serious cultivation problems. Wild allies of C. sativus possess a wide range of interesting characters which could be incorporated by means of species crosses. In the past, attempts to achieve such crosses have failed. Important characters of Cucumis species are mentioned and biosystematic problems discussed. Results of previous research on species crosses prompted an examination of the prospects of further research. |
