Potato is a major food crop in the mid-hills and mountains in Nepal. Traditionally, most farmers use small tubers as seed, to grow potato with the minimum input. Although seed tubers are easy to plant and plants grow quickly, they are expensive and may account for more than half the total production costs. Also, seed tubers are the main carriers of diseases and pests, they are perishable, bulky and difficult to transport. In addition, seed tubers require costly refrigerated storage facilities to prevent rotting in storage and to keep them in adequate physiological conditions until the next planting season. Conventional varieties grown by local farmers, such as Kufri, Cardinal, Kufri jyoti, Kufri Sindhuriare susceptible to late blight and vulnerable to low temperatures, leading to poor yields. Potato production from True Potato Seed (TPS) is more advantageous than using ?seed potatoes?. By planting true potato seeds, farmers maintain genetic diversity that will protect the production from any new pest or disease, or changes in climate or cultural practices. True potato seeds, or "botanical potato seed" differentiates from "seed potatoes", which are genetically identical clones produced in large numbers by planting pieces of a potato stem or tuber or through tissue culture. Conventional varieties in the mid-hill region in Nepal has been found to be vulnerable to foggy weather, cold waves and late blight disease. Hence, farmers have been producing potatoes from TPS seeds from hybrid potato varieties, like HPS 7/67 and HPS 1/13, obtaining yields of about 35 t/ha. The objective of the practice is to produce late blight and cold tolerant varieties of potato from True Potato Seed (TPS) to enhance potato yield under highly variable temperature regimes.
