Abstract

Field experiments were conducted for 3 years, i.e. from 1977 to 1980 to study the yield losses incited by PVY and PLRV in potato varieties. The yield losses caused by PVY and PLRV varied from 13.90 to 20.12% and 7.45 to 15.74% in autumn crop and 44.03 to 57.18% and 38.83 to 60.04%. respectively, in spring crop. The losses were more in potato varieties Kufri Sndhuri followed by Kufri Chandramukhi and least in Kufri Jyoti in both the crops easons.
