ABSTRACT
Eight potato seed sources viz. tissue culture, Nagar (Gilgit), Sheshghat (Gilgit), Okara, Batakundi, Parachinar (local), Peshawar, and Jaji (Afghanistan) were compared for their performance at village Luqumankhel, Parachinar during spring 1999. Minimum days (32) to 80% emergence were taken for seed source Peshawar as compared to the maximum days of 43.75 for seed source Jaji. The difference in percent emergence among seed sources was negligible. Significantly maximum soil coverage (94.5%), plant height (57.0 cm), number of stems/plant (5.5), large size tubers weight/plant (718.0 g), marketable yield per ha (62.10 t) with no attack of early blight and potato leaf roll virus (PLRV) was in tissue culture seed source while minimum stems/plant (2.5), plant height (31.7 cm), weight of large size tubers/plant (205.5 g) and total marketable yield/ha (20.31 t) with more infestation of early blight and PLRV was observed in Peshawar seed source. Significantly highest yield of 63.30 t ha-1 was recorded from tissue culture seed source followed by 58.50, 55.66 and 52.40 t ha-1 from seed sources Nagar, Batakundi and Parachinar respectively and lowest yield of 21.07 t ha-1 from Peshawar seed source.
