Abstract: To determine the proper planting dates for true potato seed (TPS) nursery, the present study was conducted at Agriculture Research Institute, Tandojam, Pakistan located at 25.24, 46.00,’N and 68.32, 12.00^’E during 2009 and 2010. Comparison of three planting dates i.e. October 15, October 30 and November 15, were made. The results obtained from m^-2 area showed maximum germination (84.95%), plant height (46.94 cm) average number of micro (1-9 mm) tubers (196.1), small(10-19 mm) tubers (42.15), medium(20-39 mm) tubers (26.56), large(>40 mm) tubers (7.57), weight of micro tubers (1302 g), small tubers (480.3 g), medium tubers (340 g) and large tubers (468.5 g) were observed when TPS-9804 was planted on 30^th October. The overall results for tuber yield showed that TPS-9804 genotype planted on 30^thOctober produced maximum tuber yield (29.46 t ha¹) as compared to rest of genotypes; hence, TPS-9804 genotype is recommended for raising of TPS nursery with 30^th October of planting date.
