Abstract
Papaya ringspot virus (PRSV) is a devastating disease that has a detrimental impact on both commercial papaya production and Caricaceae germplasm conservation.
Transgenic line 55-1 and derived progeny ‘SunUp’ and ‘Rainbow’ are resistant to PRSV and have saved the papaya industry in Hawaii.
In small scale replicated field plots we were able to protect susceptible Caricaceae germplasm using PRSV resistant transgenic papayas as border plantings in the presence of both the aphid vector and PRSV-infected plants.
Currently we are testing this concept in commercial field sites by combining aphid vector monitoring and early detection of PRSV with the hopes that this may serve as a model for coexistence of conventional and genetically modified crops.
