The Rainbow papaya is an F-1 hybrid variety of papaya produced by crossing Hawaii's yellow-flesh Kapoho Solo variety with the red-flesh SunUp. Researchers from Cornell University and the University of Hawaii had done research since 1984 to develop this Rainbow variety, which includes a gene that made the papaya plants resistant to the ringspot ...

Rainbow’ papaya is a new hybrid variety developed by the College of Tropical Agriculture and Human Resources of the University of Hawaii at Manoa. ‘UH Rainbow’ combines the superior quality typical of Hawaii’s “solo” papayas with excellent resistance to a devastating plant virus disease—papaya ringspot virus (PRSV).

Part of this strategy was funding the Hawaii Department of Agriculture to develop a transgenic variety of papaya that would be resistant to papaya ringspot virus. This success story of one of the few public-sector developed GM crops in North America.

Rainbow is a papaya variety that was genetically engineered to resist infection from a virus which weakens and eventually kills papaya trees. Papaya ringspot virus entered Puna, Hawaii’s major papaya growing area, in 1992, and by 1994 all farming areas in Puna, where up to 96% of Hawaii’s papaya crop was grown, had become infected.

2022年8月7日 · Rainbow papaya (Carica papaya L.) is a genetically engineered (GE) cultivar with resistance to papaya ringspot virus (PRSV). This cultivar currently accounts for about 70% of Hawaii’s papaya acreage.

Thankfully, Gonsalves, a Hawaiian-born scientist at Cornell University, developed a genetically modified papaya, known as the Rainbow papaya, designed to be resistant to the virus. Gonsalves and his team planted a trial of the Rainbow papaya on the island of Puna.

Particularly, in the 1990s, the introduction of genetically modified papaya named "Rainbow papaya" against the epidemic of papaya ringspot virus has prevented the collapse of the Hawaiian...

2006年1月1日 · The transgenic papaya cultivars Rainbow and SunUp were released commercially in Hawaii in 1998 and virtually saved Hawaii's papaya industry from the devastation being caused by Papaya ringspot virus (PRSV). This chapter focuses on the development, release and impact of the PRSV‐resistant transgenics.

2011年3月1日 · Rainbow papaya (Carica papaya L.) is a genetically engineered (GE) cultivar with resistance to papaya ringspot virus (PRSV). This cultivar currently accounts for about 70% of Hawaii's papaya acreage.

2013年1月1日 · In May 1998, papaya ring spot virus (PRSV)-resistant transgenic “Rainbow” and “SunUp” papaya were released to growers and helped save the papaya industry in Hawaii. This review provides a personal account of the Hawaii transgenic papaya story from 1978 to 2012.
