An experiment was carried out at Sakha Agricultural Research Station during 2010 and 2011 seasons to study the effect of storage periods, cultivars, environments and package materials on germination, viability and seedling vigor of wheat grains.                 Three cultivars of wheat (Gemmiza7, Sakha 93 and Giza 168) were used during this study. Grains were packaged in three package materials (Jute, Jute coated plastic, Metal cans) after that grains stored in three types of environments (Dust, Sand and Ash). The stored grains were tested after two different periods for germination, viability (Electrical conductivity and Acidity %) and seedling vigor (radical length, plumule length and seedling dry weight). The obtained results recorded highly significant differences among the tested cultivars for all studied characters. Moreover, increasing storage period after harvest until 18 months decreased significantly all characters except electrical conductivity and acidity percentage which were increased with increasing storage period. Also, highly significant differences were observed among grains quality characters due to the different storage environments. Grains stored in ash had the worst characters as compared with other environments while grains stored in dust and sand gave the best characters. Moreover, grains stored in metal cans produced the best characters while, grains stored in jute bags gave the worst characters. It could be recommended that using metal cans to store wheat grains tell 18 months without using any chemicals is the best method for saving viability and seedling vigor.
