An experiment was carried out to screen 16 papaya genotypes against the papaya ringspot and leaf curl virus diseases during 2010–11 under field conditions at IARI, New Delhi. The most of the genotypes showed suceptibility against the papaya ringspot virus and some of them had expresssed tolerance. However, in case of the leaf curl virus non of the genotypes has shown the tolerance except the Sinta. The different level of of the infection of leaf curl virus was observed during peak of the rainy season. Genotypes P-7-9, Sinta, Pune selection-3, P-7-2 and RCTP-1 could be incorporated in the future breeding programme to develop the tolerant genotypes.
