What are ‘agricultural biotechnology’ and ‘genetic modification’?
Agricultural biotechnology encompasses a range of modern plant
breeding techniques. For centuries, farmers have tried to improve their
crops by means of crossing, relying on the random rearrangement of
existing genes between two closely related parent plants. Modern
agricultural biotechnology improves crops in more targeted ways. The
best known technique is genetic modification, but the term agricultural
biotechnology (or green biotechnology) also covers such techniques as
Marker Assisted Breeding, which increases the effectiveness of
conventional breeding. Whatever the particular technology used, the
crops may be destined for use for food, biomaterials or energy
production.
Genetic modification means that existing genes are modified or new
genes included to give plant varieties desirable characteristics, such
as resistance to certain pests or herbicides, or for vitamin
fortification. Because only a few genes with known traits are
transferred, GM methods are more targeted and faster than traditional
breeding. They are used alongside conventional plant breeding.
