Virus-resistant papaya
Papaya genetically modified to be resistant to the Papaya Ringspot Virus (PRSV) were developed by the University of Hawaii and are primarily planted there. Some reports claim that these crops have saved the Hawaiian Papaya industry from devastation whilst others claim valuable export markets have been lost and that the disease could have been controlled in other ways.
