Up to 70% success has been achieved using a simple technique of in ovulo embryo rescue for generating progeny From crosses between Allium cepa and A. fistulosum and other wild species of Allium. Pollen storage in liquid nitrogen has overcome problems associated with lack of synchrony of flowering between Allium species. The use of pollen tube growth for predicting crossability is brought into question.
