Summary
A cross between Allium roylei Stearn and A. cepa L. and a backcross of the probable interspecific hybrid to Allium cepa L. were realized in a simple and practical way, possibly opening up perspectives for introgression of downy mildew resistance and other characters from this wild relative into the onion germplasm.
