1. In the present research, cytogenetical studies on the F1 plant raised from T. polonicum×S. africanum were carried out in meiosis of PMC's.
2. In general, the external characters of F1 plant resembled to the parents, but more closely to T. polonicum as the mother plant (Photo. 1).
3. At the heterotypic metaphase in meoisis of PMC's of F1 plants, 03 bivalents or 1521 univalents were observed (Table 2). The bivalents may probably be made by autosyndesis between the chromosomes of AB genomes of T. polonicum.
4. The F1 plant has the property of self pollination as in T. polonicunm used as the mother plant.
5. The F1 plant shows some fertility in natural selfing though lower in percentage (Table 1).
