Research
Motivated by the upcoming food crisis problem of
malnutrition in
developing countries and the potential of
gene technology to contribute to food security, Potrykus and his research group dedicated their work to genetic engineering projects aimed at improving yield stability and food quality of crops such as
rice,
wheat,
millet,
sorghum, and
cassava. The most significant development so far has been the creation of golden rice, a new rice variety providing
vitamin A. This strain of rice is widely seen as the model example of how to sustainably reduce malnutrition in developing countries. Potrykus began thinking about using genetic engineering to improve the nutritional qualities of rice in the late 1980s. He knew that of some 3 billion people who depend on rice as their staple crop, around 10% risk some level of vitamin A deficiency. This problem interested Potrykus for numerous reasons, including the scientific challenge of transferring not just a single gene, but a group of genes that represented a key part of a biochemical pathway. In 1993, with funding from the
Rockefeller Foundation, Potrykus teamed up with
Peter Beyer and they launched what would become a seven-year, $2.6 million project to develop Golden Rice. Since his retirement in 1999, Ingo Potrykus - as president of the International Humanitarian Golden Rice Board - has devoted his energy to guiding Golden Rice towards
subsistence farmers across the many hurdles of a GMO-crop. To this end he has been established collaboration with 14 rice institutions in
India,
China,
Vietnam,
Bangladesh,
Indonesia, and
Philippines. In 2013 Potrykus met the Pope who offered his personal blessing to Golden Rice although the Pope was concerned that genetic modification benefited big business rather than the poor. ==Personal life==
