Research using wild relatives of the soybean, such as Glycine falcata Benth., a native of Australia, has been hampered by an extremely low seed set under greenhouse conditions in the absence of pollinating vectors. A quick and efficient method of enhancing seed set in this species was developed in working with Neonotonia verdcourtii, a species from Africa formerly included in the genus Glycine (Isely et al., 1980). Conventional soybean crossing techniques among flowers of one plant were tedious and time-consuming, and did not produce many seeds.
