 abstract = {In the first such study of its kind, we examined gene flow potential between a valued native plant and a popular cultivar. We studied outcomes of controlled hybridization between Echinacea purpurea and a conspecific cultivar, E. purpurea 'White Swan', by comparing levels of competitive ability and reproductive potential. Differences in plant performance of wild-types and Fl's were studied at three densities (20.3, 45.7, and 182.9 plants/m(2)) using a field competition experiment. Wild-types were slightly larger but F(1)s had higher reproductive output. These differences can be attributed to floricultural breeding of the cultivar parent. Based on the results of this research, if the initial hybridization between the wild-type and cultivar were to occur, it is anticipated that the resulting Fl generation would survive and reproduce, creating the potential for continued gene flow. This methodology has potential for use in risk assessment of plant introductions, including transgenic crops. (C) 1998 Elsevier Science B.V. All rights reserved.},
