veränderter Nutzpflanzen (Quelle: Orton 2003: 10)
Crop modification Description Aims
Commercialisation
Insect resistance • Bt cotton resistant to cotton bollworms,
pink bollworms and tabacco budworms
Virus resistance • Papaya resistant to ringspot virus • Increased yield
Field studies
14
• Reduced insecticide use, better pest
control, protected yields
Fungal resistance • Bananas resistant to black sigatoka • Crop protection and production, reduced
use of fungicide
Virus resistance • Cassava with increased resistance to
African cassava mosaic diseases
• Sweet potato resistant to feathery mottle
virus
• Crop protection
Bacteria resistance • Rice resistant to bacterial blight disease • Benefits to producers
Ripening control • Banana, pineapple, strawberries, tomatoes
Factory plants • Rice producing hepatitis A antibodies
for use in vaccines
Greenhouse studies
• Extended marked life
• Cost savings
Pest resistance • Potatoes resistant to nematodes • Reduced pesticide use
Research laboratory studies
Antibiotic stress • Tabacco to grow in waterlogged conditions
• Crops resistant to aluminium toxicity,
such as rice in Mexico
• Rice resistant to salt (China)
• Crops resistantt to drought
Nutrition enhanced • Rice rich in vitamin A
• Plants with increased levels of iron and
folic acid
• Canola oil rich in vitamin A
• Sweet potatoes and rice with enhanced
protein
• Vegetables that keep their vitamins
when cooked
• Increased yield
• Trials at relatively early stage
• Improved nutrition content
• Possible future development
• Improved nutrition, thought to be at least
eight years from development
Production enhanced • Sugar cane with increased sucrose • Better appearance and higher yield
