Summary of scientific research
Prof. Potrykus’ work centred on the development and application of genetic engineering technology for and to ‘food security’ crops such as rice (Oryza sativa), wheat (Triticum aestivum), sorghum (Sorghum bicolor), and cassava (Manihot esculenta), in order to solve problems that are difficult to treat with traditional techniques. He also focused on the areas of disease- and pest resistance, improved food quality, improved yield, improved exploitation of natural resources, and improved bio-safety. He is the inventor and promoter of ‘Golden Rice’, a sustainable contribution to reduce vitamin A-malnutrition (www.goldenrice.org).
