Bt maize in the Üplingen Plant Science Garden Numerous varieties of conventional and genetically modified maize can be seen in the Üplingen Plant Science Garden. Several varieties employ the Bt concept: they produce an agent that protects them from pests such as the European corn borer and the Western corn rootworm. |
