In: Journal of the Advances in Agricultural Researches 2013.v.18(1)Summary: Using indirect ELISA and five antisera specific to important potato viruses, potato plants of cv. Spunta naturally infected singly with Alfalfa mosaic vrus (AMV), Potato leaf roll virus (PLRV) and Potato virus Y (PVY) at two stages of plant development were chosen and targeted in the field to determine the effect of such virus infection on the vegetative growth and productivity of the infected plants. Vegetative growth parameters represented by plant height average number of leaves per plant fresh and dry weight of root and shoot systems were significantly reduced by virus infection. Great reduction was observed with plants infected at 5-6 leaf stage with AMV, PLRV and PVY. The same trend was also observed with productivity parameters represented by number of tubers per plant, weight of tubers per plant, dry matter and tuber size.
