Abstract:
Potato is grown as a rainfed and irrigated crop in the cooler highlands and mid-altitude regions of the
tropics. Its productivity is very low mainly due to unavailability of healthy and sufficient amount of
seed potatoes to the farmers. The utilization of true potato seed (TPS) can be considered as an
alternative method to produce potatoes, thereby alleviating the problems associated with seed potatoes.
The first aim of the research report in this thesis was to study problems related with poor TPS
germination. The second aim was to determine the best growing season to grow TPS for seedling
tuber production. The third aim was to develop appropriate seed bed management practices for
maximum seedling tuber production.
