Papaya ring spot disease management: A review

Abstract

Papaya Ring Spot Virus (PRSV) is one of the major obstacle for boosting papaya production in the country. Until now there is no absolute curative control measure available through conventional methods. Precautionary measures for PRSV incidence viz. rouging, cross protection, vector controls etc. are not much helpful. The, transgenic (GM) papaya varieties viz. Rainbow and SunUp were developed at Hawai in 1998. However, in the present scenario, in countries like India where there is legal restrictions on research on genetically modified (GM) food crops, introgression of the PRSV-P resistance gene into C. papaya from its wild relatives (species of Vasconcellea) is the one of the optimistic option available with researchers.
