Abstract
Four true potato seed (TPS) hybrids were evaluated for tuber yield with a standard variety (Diamont) at Naltar Seed Valley Northern Areas, Gilgit during the 2005 crop season. Various agronomic parameters like number of stems per plant, seedling vigor, number of tubers per m2, yield of tubers per hectare and grading weight percentage were assessed. The TPS hybrids Atzimba x TPS-67 and LT-8 x TPS-67 gave greater tuber yield (43 tons/ha) than the standard variety Diamont. Diamont and the TPS hybrid MF-I x TPS-67 did not significantly differ for tuber yield per hectare whereas the TPS hybrid MF-II x TPS produced the lowest number of tubers per m2, number of tubers per plant, number of tubers per m2 and yield per hectare (29.2 ton). On the basis of this study, it is concluded that TPS parent TPS-67 (male parent) has a better combining ability with TPS parents LT-8 and Atzimba, hence true potato seed (TPS) of these hybrids are recommended for general cultivation in Northern Areas of Pakistan.
