Abstract

A method for improved production of hybrid seed under genetically (genic or cytoplasmic) induced male sterility of the female line. More specifically, differential genetic response to specific herbicides is used to grow a mixture of a male-sterile female line that is also resistant to the herbicide and a fertile male line that is also susceptible to said herbicide in the production field and spray the mixture of male and female plants with herbicide at a late development stage that will damage the male plants only to prevent normal seed development after pollen shedding by the male plants. The production field is harvested by a combine harvester and the undeveloped male seeds are screened away, and only the normally developed hybrid seeds are harvested. In an alternative method, no herbicide is used.
