This contribution is based mainly on ongoing research in an EU Framework 5 research programme. Wheat is a self-compatible, wind-pollinated species whose flowers are often cleistogamous. Crop to crop gene flow is very limited. Field experiments demonstrate that the distance of wheat pollen dispersal ...

This chapter discusses the possibility of enhancing crop biodiversity through genetic engineering. It also discusses the constraints to crop biodiversity, how biodiversity can be gained or lost, regulatory impediments in enhancing biodiversity, and new molecular methods that could assist in...
