 The final assessment of adaptability will depend upon how well the variety  is accepted by farmers in various locations over a period of years.  In this reportt the response of the characteristics or varieties to locati onal or seasonalvariation is analyzed.  It is not necessary to take many years to evaluate varietal difference ofadaptability in characteristics such as date of maturity or tuber weight, but necessary to take many locations except stem length and tuber yield.  It is found that the tuber number which is controlled mainly by predictabl e factors has a great effect on starch yield.
