elite cultivars with wild members of the same species or even with more
distant relatives. Biodiversity can also be generated through mutagenesis.
Targeted engineering by transgenic approaches will allow breeders to exploit
knowledge and gene pools, even across species borders. Agricultural prac-
tices such as mixed cropping, improved fertilisation regimes, and improved
harvesting and storage procedures might also marginally contribute. With
respect to plant mineral nutrients, the ultimate breeding goal is to improve
uptake and internal use efficiency in novel crop cultivars in order to reduce
losses, reduce costs and maintain high yields and high quality of the harvested
material. All approaches have to take into account the paradigm of retaining
the very high yield potential of modern crop cultivars or the goal of providing
more food for a growing population on less land, environmentally sustainably
and affordably, will not be met.
