Discussion
Crop-wild/weed hybridization has
generated great concerns simply because gene flow can be an avenue for
transgene escape, which could alter the genetic make-up of both
populations (Ellstrand and Holfman 1990; Song et al. 2004). Evaluation
of the fitness of crop-wild hybrids and their parents, especially the
wild parents, is a direct way to investigate the potential consequences
of crop-to-wild gene flow (Snow et al. 1998). In this study, agronomic
comparisons were evaluated among GM soybean, wild soybean and their
F1, F2 and F3 progenies,
with implications for transgene escape from GM soybean varieties,
resulting in a better understanding of its consequences.
