Summary
We propose that research be increased on chemical restoration of fertility to the genetic male steriles of barley. Seed harvested from male-sterile plants restored to fertility can then be planted as the female for hybrid barley production. Male fertility has been resotred in male-sterile or gynoecious plants by chemicals in many species, but a satisfactory method has not been developed in barley. Male-sterile mutants that self and mutant-chemical combinations with fertility persisting into the second generation should be avoided.
