Potato viruses like PVX (Potex virus X), PVY (Poty virus Y) and PLRV (genus Polerovirus, family Luteoviridae) cause significant yield loss of potato crop in the world including Pakistan. In this regard, 30 exotic potato genotypes were screened against the PVX, PVY and PLRV in field conditions during two seasons 2015-2016. Results showed that all the genotypes had resistance against PVX and PLRV however four genotypes (CIP-3, CIP-9, CIP-11 and CIP-14) were susceptible to PVY. Results regarding yield and tuber external quality showed that CIP-30 was taller genotype with medium number of tubers and shoots plant-1 while CIP-5 was a dwarf genotype with minimum tuber yield. Genotype CIP-6 produced more number of tuber plant-1 but CIP-22 followed by CIP-10 produced the highest tuber yield plant-1. Majority of genotypes produced round shape tuber with yellow, white skin color and cream flesh. Likewise, maximum genotypes had medium to shallow eye tubers except CIP-9 and CIP-13, which had deep eyed potato tubers. In short, genotypes CIP-3, CIP-9, CIP-11 and CIP-14 showed susceptibility to PVY virus. Among resistant genotypes, CIP-10 and CIP-22 possessed greater yield and could be suggested for commercial cultivation in Pakistan.
