This article reviews
some of the highlights of modern plant biotechnology and discusses the
potential applications of biotechnology in the betterment of farming
systems in the next millennium. Plant biotechnology will facilitate
the farming of crops with multiple durable resistance to pests and diseases,
particularly in the absence of pesticides. Likewise, transgenes or marker-assisted
selection may assist in the development of high yielding crops, which
will be needed to feed the world and save land for the conservation
of plant biodiversity in natural habitats. Hence, crops should be engineered
to meet the demands and needs of consumers. The genetic base of crop
production can be preserved and widen by an integration of biotechnology
tools in conventional breeding. Similarly targeting specific genotypes
to particular cropping systems may be facilitated by understanding specific
gene-by-environment interaction(s) with the aid of molecular research.
High quality crops with improved nutritional and health characteristics
as well as other aspects of added-value may be obtained through multidisciplinary
co-operation among plant breeders, biotechnologists, and other plant
scientists. Co-ordinated efforts between consumers, policy makers, farmers
and researchers will be required to convert the various aspects of a
crop ideotype into components of new and improved farming systems of
the next millennium.
