Abstract:

Potato is an important vegetable crop in Pakistan. Reduction in area and production of potato has been observed due to various diseases among them PVX, PVY and PLRV are more important. Yield losses due to these viral diseases are up to 40-80%. Fifty eight varieties/advance lines were screened for the resistant source against PVX, PVY and PLRV in a field trial conducted at research area of Plant Virology Section, Plant Pathology Research Institute, AARI Faisalabad during 2012-2013. Out of 58 lines/varieties on the basis of ELISA results 35 line/varieties including them Hermes, Lady Rosetta and Crusier and other found to free from PVX .Ten lines/varieties showed moderately resistant response and 11 Lines/varieties showed Moderately susceptible response against PVX virus. Two line/varieties showed susceptible response against PVX i.e. 9814 and Desiree. Two varieties/lines were found resistant against PVY i.e. Lady Rosetta, Crusier. 11 were moderately resistant and 7 were moderately susceptible against PVY virus. 34 varieties/lines including them FSD-RED, FSD-WHITE, NARC 394012-962,SH-5, KARODA, Cardinal, Astrix, Sannte, Desiree, FD 69-1 and other were susceptible against PVY. Similarly 19 varieties/lines 19 were found free from PLRV disease. 10 lines/ varieties i.e. FD 78-36, FD 74-51, FD 78-104, FD 76-67, FD 78-3, FD 61-3, NARC, 394574-72, ZS-1, N-34 and SH-704 were moderately resistant against PLRV. 10 varieties/lines were moderately susceptible against PLRV. 19 varieties/lines i.e. including them FD 69-1, FSD –RED, FSD-WHITE, Karoda, Cardinal, Astrix, Diamont, Desiree and other were found susceptible against PLRV disease.
