The requirements for long and medium term seed storage are different. Even under most ideal conditions of storage, loss in seed viability can not be checked but it could be substantially reduced. The loss of seed viability leads to loss of genetic characteristics (genes). This requires frequent regeneration. The most ideal conditions which have been created for seed storage are energy dependent, capital intensive and expensive. Therefore, it has been suggested to conduct research in areas where the temperatures during most parts of the year are sub-zero, to study the suitability of the region for long-term storage of germplasm under natural conditions. It has also been suggested to study the suitability of various moisture vapour proof containers for seed packaging under such conditions.
