GYNOGENESIS TO BYPASS CROSSING BARRIERS BETWEEN DIPLOID AND TETRAPLOID DIANTHUS SPECIES.
Efforts were made to transfer the interesting characters of the tetraploid into the diploid carnations through crossing. The offspring obtained was triploid which prohibited necessary further backcrosses. In order to bypass this barrier, it was attempted to produce diploid plants from the tetraploids by gynogenesis, and to use them as crossing parents at the diploid level.
In this poster the results of a preliminary study are presented.
