Abstract
SPECIES hybrids have been reported in Petunia1 and Lycopersicum2 which can only be made in one direction, namely, when the self-fertile species of the pair is used as female parent and the self-incompatible one as male3. This phenomenon, which may be called ‘unilateral hybridization’, also occurs with some species of Antirrhinum.
