There is a genetically modified virus-resistant papaya grown in Hawaii and some is also grown in China. The first GM papayas were commercially grown in Hawaii in 1998 and the Rainbow were first imported to Canada in 2003.
There is around 1000 hectares of GM papaya grown in the US and 6895 in China.
The GM papaya is generally celebrated as having saved the papaya industry in Hawaii from the Papaya RIngspot virus. However, the GM papaya has also resulted in widespread contamination.
The papaya was developed by the University of Hawaii.
