Abstract
TPS is a botanical seed and does not carry major virus diseases. It is less susceptible to late blight disease (Phytophthora infestans), easy to store and transport. It has become alternative for production of high quality planting materials in those areas where resource poor farmers are using degenerated tuber seeds. Since it has good potential in a country like Nepal, TPS families received from the International Potato Center, Lima, Peru were evaluated and compared with HPS II/67 for their adaptability at different agro-ecological conditions of Nepal during 1998/1999 to 2000.
In the trials, TPS Progenies MF II x TPS 67 i.e. HPS II/67 and Serrana x TPS 67 were the best in hills, where as MF I x TPS 67 and Serrana x TPS 67 were best in terai in terms of yield and farmers' acceptance. Performance of seedling tubers of MFII x TPS 67, MFI x TPS 67 and Serrana x TPS 67 were also superior to clonal varieties such as Desiree, Kufri Sindhuri and Kufri Jyoti and are recommended for further demonstration in farmer's field conditions.
