mj, you will never get a definitive answer to this one. Some say there are 5 or 6 now. I have 2, one is known as Rob's, and produces large, excellent tasting brebas, and an average tasting main crop, IMO. The other, is the Rafed version, which produces exceptional main crop figs. Mine has not produced a breba crop yet, and I do not know if it will. Both were supposed to have come from Adriano, in Canada. A mix-up supposedly occurred along the line. As far as mine go, I consider Rob's to be a very good fig, the Rafed version a superior fig. I have no interest in getting any others, or worrying about who is right or wrong. Hope this helps.
