Synopsis Gator, Hazel, Prolific Spring, Wood's Abruzzi, and Pierre ryes showed a high frequency of polyembryony. Antelope, Caribou, Florida Black, and Tetra Petkus ryes exhibited a low frequency of twins. The region where grown, the year of production, growth type, or viability had little to do with twinning; but varietal differences were striking and consistent. A genetic basis for polyembryony in American rye varieties is suggested.
