Papaya ring spot virus (PRSV) is the most destructive disease of Papaya, responsible for yield reduction of Papaya all over the world. PRSV exhibited different types of symptoms on Papaya plant in the field like ringspot , vein clearing, vein banding, chlorosis of younger leaves, filiformy, shoestring, mosaic, mottling, stunted growth etc. Molecular diagnosis of PRSV was done with the help of gene specific primers through PCR. Gel electrophoresis results show a 300bp clear band which confirms the presence of PRSV in the plants. Sequencing was done and phylogenetic tree was made.
