Wide Hybridization in Higher Plants by Applying the Method of Test Tube Pollination of Ovules
The method of placental pollination enables to overcome some pre- and postzygotic barriers of incompatibility. By applying this technique it was possible to obtain hybrid embryos and even plants mainly among some species of Solanaceae, Caryophyllaceae and Brassicaceae. The newest findings show that in Brassicaceae fertilization and hybrid embryos developent can occur between species belonging to different genera. No methods are available to enhance hybrid embryo differentiation beyond the globular stage.
