A total of 241 intergeneric combinations between Hordeum and Secale were attempted. It was only possible to obtain hybrid offspring from combinations with Hordeum as the female parent. By the aid of embryo culture technique 81 intergeneric combinations were synthesized, 72 of them not reported earlier. Generally hybridization with the polyploid species of Hordeum was most successful. Morphologically the hybrids were intermediate to the parents in most characters, though an obvious effect of genome dosage could be observed. Only few deviations from the expected chromosome numbers of the hybrids were found. All hybrid plants showed complete male sterility.
