The genetic control of Endosperm Balance Number (EBN) was studied using trisomics and induced mutation. In order to induce and detect a change in a factor determining the EBN of the male, pollen from tetraploid Datura was irradiated and used to pollinate diploids. No triploids were produced in over 70 000 fertilizations. At least 70 would have been expected if the deletion of the function of a single gene could change the EBN. An attempt was made to find a particular chromosome that could alter the EBN of the female when it was present as the extra chromosome in 2x + 1 × 4x crosses. In tests of trisomics in both Datura and Solanum (potato) no chromosome could be found that changed the EBN. Therefore, it is concluded that more than one gene and more than one chromosome is involved in determining EBN. Key words : crossing barriers, endosperm, Datura, potato, speciation.
