With the objective of determining the storability for on-farm storage, cured potatoes of 5 TPS lines, viz. HPS I/13, II/13, I/67, II/67 and 7/67 were stored in a CIP designed rustic store working on passive evaporative cooling from March 15 to June 15, 1993. Three popular cultivars Kufri Badshah, Kufri Bahar and Kufri Chandramukhi were used as controls. At sixty days of storage, the sprouting was significantly higher (75–100%) in all the TPS lines than the controls (40–70%), whereas the rottage was eit4er significantly lower or equal to Kufri Chandramukhi (0.5%), the best keeper among the controls. The weight loss in all the TPS lines, except HPS 7/67 was moderate (7.2 to 7.6%) and comparable to Kufri Bahar (7.4%). At 90 days, sprouting was cent percent in all the TPS lines as well as in the controls. The weight loss in 3 TPS lines HPS, II/13, I/67 and II/67 was moderate (14–15% and comparable to Kufri Bahar 14.6%), but was higher than the Kufri Chandramukhi (9.9%). These 3 lines also showed lower rottage than Kufri Bahar. The weight loss in other two lines, viz. HPS I/13 and 7/67 was even higher (17–19%) than Kufri Badshah (17.1%), the poorest storage preformer among the controls. These results indicated moderate storability of 4 TPS lines up to 60 days and 3 lines up to 90 days of storage. None of TPS lines performed better than Kufri Chandramukhi, the white skinned best performing variety under such storage conditions.
