Golden Rice is unique because it contains beta carotene, which gives it a golden color. Many fruits and vegetables that are commonly eaten, such as squash, papaya and carrots, also get their color from beta carotene.
The body converts beta carotene in Golden Rice to vitamin A as it is needed. According to research published in the American Journal of Clinical Nutrition in 2009, daily consumption of a very modest amount of Golden Rice – about a cup (or around 150 g uncooked weight) – could supply 50% of the Recommended Daily Allowance of vitamin A for an adult.
Golden Rice was developed using genetic modification techniques, with genes from maize and a common soil microorganism that together produce beta carotene in the rice grain. Surveys of rice varieties around the world failed to identify any varieties that contain significant amounts of beta carotene, so conventional breeding programs could not be used to develop Golden Rice.
Golden Rice was invented by Professor Ingo Potrykus, then of the Institute for Plant Sciences, Swiss Federal Institute of Technology, and Professor Peter Beyer of the University of Freiburg, Germany. By 1999, Professor Potrykus and Dr. Beyer produced a prototype Golden Rice and published their landmark research in Science.
The inventors’ desire to donate Golden Rice as a gift to resource-poor farmers in developing countries led to a public-private partnership with Syngenta to help further develop Golden Rice.
Scientists at Syngenta then carried out additional laboratory, greenhouse, and field research to help raise the beta carotene levels in Golden Rice. In 2005, they developed a new version of Golden Rice that produces substantially more beta carotene than the 1999 prototype - as published in Nature Biotechnology.
Syngenta arranged royalty-free access to the patents and intellectual property, held by several biotechnology companies, for a number of key technologies used in Golden Rice. This allows IRRI and others to develop Golden Rice varieties on a non-profit basis.
The inventors, with the help of Adrian Dubock, also established the Golden Rice Humanitarian Board and the Golden Rice Network of public sector institutions through which they continue to actively work to enable the development and introduction of local Golden Rice varieties that would be well-suited to the different target countries.
IRRI is the coordinating institution for the Golden Rice Network and has been working to develop Golden Rice with national partners since 2006.

IRRI is working with others to develop Golden Rice as a potential new food-based approach to improve vitamin A status. Our work will:
Develop varieties suitable for Asian farmers
Breeders at the Philippine Department of Agriculture - Philippine Rice Research Institute (DA-PhilRice), the Bangladesh Rice Research Institute (BRRI), and the Indonesian Center for Rice Research (ICRR) are developing Golden Rice versions of existing rice varieties that are popular with their local farmers, retaining the same yield, pest resistance, and grain qualities. Cooking and taste tests will be done to help make sure that Golden Rice meets consumers' needs. Golden Rice seeds are expected to cost farmers the same as other rice varieties.
Help assess the safety of Golden Rice
To help assess the safety of Golden Rice in the environment, field tests and other evaluations will be done in each partner country. Golden Rice will be analyzed according to internationally accepted guidelines for food safety.
The national rice institutes plan to submit all safety information to government regulators who will review these data as part of the approval process for Golden Rice before it can be made available to farmers and consumers.
Evaluate whether consumption of Golden Rice improves vitamin A status
If Golden Rice is approved by national regulators and deemed safe for human consumption, Helen Keller International (HKI) will independently evaluate the efficacy of Golden Rice; in other words, whether or not it improves vitamin A status.
With other international experts and local partners, a community nutrition study will be implemented to evaluate if eating Golden Rice every day will improve vitamin A levels in real world conditions. This is necessary to determine the potential for Golden Rice to be used as a public health approach for reducing vitamin A deficiency.
Explore how Golden Rice could reach those most in need
IRRI is now collecting information to develop strategies to ensure that Golden Rice could reach farmers and consumers. If Golden Rice is found to be safe and efficacious, a sustainable delivery program will ensure that Golden Rice is acceptable and accessible in vitamin A deficient communities. If approved by national regulators, IRRI and others will continue to work together to introduce Golden Rice as another food-based approach to improve vitamin A status.
Other work on Golden Rice
Additional research in this project is being conducted by the University of Freiburg to develop Golden Rice varieties with even higher levels of beta carotene.
Our experiences in developing, evaluating, and planning the delivery of Golden Rice in the Philippines, Bangladesh, and Indonesia will be important in designing plans for Golden Rice in other countries.
In addition to the IRRI-led Golden Rice project in Bangladesh and the Philippines, work to develop Golden Rice is underway at research institutes in India, Indonesia, and other countries. More information about their work, and current activities of the inventors and the Golden Rice Humanitarian Board, can be found on www.goldenrice.org.
The International Rice Research Institute (IRRI) is working with a range of other organizations and individuals on the Golden Rice project. They bring additional expertise in nutrition, plant science, agriculture, biosafety, stakeholder outreach, and communication, and provide financial support.
International Rice Research Institute (IRRI)
IRRI is a nonprofit independent research and training organization, the largest in the world focused on rice. It develops new rice varieties and rice crop management techniques to help address poverty and hunger and improve the health of rice farmers and consumers while ensuring rice production is environmentally sustainable.
IRRI is the administrative lead organization for this Golden Rice project, coordinating the work of other partners with expertise in agriculture and nutrition to introduce Golden Rice in the Philippines and Bangladesh.
IRRI is directly involved in several agriculture-related aspects of the project, including initial breeding work to insert the Golden Rice trait into leading rice varieties that were selected by the national rice research institutes, PhilRice and BRRI. This involves laboratory work, greenhouse tests, and some preliminary field evaluation. Potential Golden Rice varieties are then transferred to the national rice institutes for further development and assessment.
IRRI’s other contributions to this project include:
- Providing technical support and training to help with breeding and development,
- Building scientific capacity at the national level,
- Assisting in developing locally adapted plans to deliver Golden Rice to farmers and consumers, and
- Participating in research and collation of data to assess the safety of Golden Rice for human health and the environment.
IRRI has been working with Golden Rice for more than ten years and since 2006 has been the coordinator of the Golden Rice Network, a group of national agriculture research institutions around the world that are helping to breed Golden Rice into local varieties for the benefit of farmers in their countries.
Philippine Rice Research Institute (PhilRice)
PhilRice is a government corporate entity attached to the Department of Agriculture. PhilRice was created through Executive Order 1061 on the 5th of November 1985 (as amended) to help develop high-yielding and cost-reducing technologies so farmers can produce enough rice for all Filipinos.
PhilRice accomplishes its mission through research and development work in its central and six branch stations, coordinating with a network that comprises 57 agencies and 70 seed centers strategically located nationwide.
To help Filipino farmers achieve holistic development, PhilRice pursues the following goals of attaining and sustaining rice self-sufficiency; reducing poverty and malnutrition; and achieving competitiveness through agricultural sicence and technology.
Because one of its primary functions is to conduct rice research that caters to the nutritional needs of consumers, PhilRice leads the development of new Golden Rice varieties that are tailored to specific rice-growing conditions in the Philippines. One popular rice variety currently being developed by PhilRice to have a Golden Rice counterpart is PSB Rc82 (Peñaranda), a popular, high-yielding, and widely grown rice variety. PhilRice is conducting field tests and trials of Golden Rice, in accordance with regulatory requirements. PhilRice works closely with national stakeholders across the Philippines.
PhilRice has been involved with the Golden Rice Network for many years. It is also developing a ‘3-in-1’ variety of Golden Rice, which will have resistance to tungro and bacterial blight, two of the most devastating rice diseases in the country.
Bangladesh Rice Research Institute (BRRI)
BRRI is the national agency in Bangladesh responsible for rice research and development.
BRRI leads the development of Golden Rice in Bangladesh. It is managing the selection and development of rice varieties with the Golden Rice trait, beginning with BRRI dhan29, one of the most important varieties in Bangladesh. BRRI will conduct field evaluations of Golden Rice in Bangladesh for several seasons and undertake other biosafety research required for regulatory review of Golden Rice in the country. BRRI also interacts with other public- and private-sector institutions in Bangladesh that are active in nutrition, seed delivery, and other areas related to Golden Rice.
BRRI is an active and long-standing member of the Golden Rice Network, at the forefront of work to adapt Golden Rice to specific rice-growing conditions in Bangladesh.
Indonesian Center for Rice Research (ICRR)
ICRR is part of the Indonesian Agency for Agricultural Research and Development (IAARD).
Breeders at ICRR are developing Golden Rice varieties which are suited to the local environment. ICRR is working with the Golden Rice trait in the local varieties that are popular with farmers, including Ciherang and IR64. Ciherang is a popular rice variety that is planted on more than 40% of total rice area across many parts of Indonesia.
ICRR is also gathering data that will be needed by regulators in order to assess the safety of Golden Rice. Golden Rice will be analysed according to internationally accepted guidelines for environmental and food safety. ICRR plans to submit all safety information to government regulators who will review these data as part of the approval process for Golden Rice before it can be made available to farmers and consumers.
Biotechnology Coalition of the Philippines (BCP)
BCP is a stakeholder organization advocating for the safe and responsible use of modern biotechnology for the attainment of national development goals in the Philippines. Its members include scientists, teachers, doctors, medical school professors, students, farmers, clergy, civil society advocates, and media practitioners. BCP organizes and participates in frequent dialogue activities, many in conjunction with governmental authorities, with people on all sides of the biotechnology issue in the Philippines at both the national and provincial levels.
BCP helps ensure this participatory and inclusive approach guides all Golden Rice stakeholder outreach activities – which take place at regular intervals and key milestones throughout the life of the project.
Helen Keller International (HKI)
Founded in 1915, HKI is an international nongovernmental organization dedicated to saving the sight and lives of the most vulnerable and disadvantaged. HKI combats the causes and consequences of preventable blindness and malnutrition by establishing programs based on evidence and research in vision, health, and nutrition.
HKI will serve as an independent evaluator to determine the efficacy of Golden Rice, that is whether its consumption improves vitamin A status. This evaluation will only take place if Golden Rice is approved by national regulators and deemed safe for human consumption. HKI will also work to ensure that, if it is deployed, the product will reach those at risk of vitamin A deficiency, who are often the poorest groups in society.
