Abstract
Effect of microtuber formation in long term keeping with and without growth retardants under dark conditions revealed in presence of BAP and CCC, the period of microtuber formation was reduced from120day to 90 days. The optimum level of 5 mgl-1 BA and 500 mgl-1 CCC obtained maximum weight and size of microtuber. The varietal differences were significant and Kufri Pukhraj found best for the weight and size of microtuber. The level 500 mgl-1 CCC favours the increase microtuber weight irrespective of the presence of cytokinin.CCC at both lower and higher level than this reduced the microtuber weight. Effect of storage temperature and duration of storage on microtuber dormancy were evaluated and find out that the best dormancy breaking treatment was 25 °C. Among different temperature 4°C temperature reported no germination and may be used for storing the microtuber up to six month period.
