S ummary Hybridizations were carried out between samples of ten diploid Dactylis subspecies. Both pollen fertility and ‘fertility index’ of hybrids decreased from initial cross to F 2 . There was no correlation of fertility with geographical distribution of the parents, and despite the fall in hybrid fertility it was considered that gene exchange would not be completely prevented.
