The invention relates to materials and methods useful for controlling the unwanted spread of transgenic traits. The methods involve an apomictic plant containing a transgene for a desired trait and a transgene causing seed infertility. The methods also involve one or more transcription activators that activates expression of both transgenes carried by the apomictic plant. The transcription activator(s) activates expression of both transgenes in the female. Seeds that are formed on such plants are infertile.
