If GMO genes escape, how will the hybrids do? Fitness and growth of sorghum, shattercane, and its wild-crop hybrid in Nebraska

Genetically modified organisms (GMOs) may raise concerns of genes escaping from crops and having unknown effects on natural, wild species. But what is the real risk that traits associated with GMOs will actually migrate to and persist in their wild relatives? Interest in plant ecology, crop production and weed management led researchers to investigate how gene flow from a cultivated crop to a weedy relative would influence the ecological fitness of a cropwild hybrid offspring.
