Description

Reciprocal crosses were made between H. cannabinus (2n=36) and H. radiatus (2n=72). An F1 plant was obtained only when H. cannabinus was used as the female parent. The F1 plant grew vigorously and was totally sterile. In pollen mother cells, 18II + 18I was most freguently observed. Judging from these results, the tetraploid species, H. radiatus, contains one genome which is homologous with that of H. cannabinus and another genome which is not.
