This study was conducted at the seed technology department during 2016-2017 years to investigate the effect of some storage conditions i.e. storage times (after harvest, 6 and 18 months), location (Sakha and Sids), form of wheat (grain and spike) and six wheat cultivars (Sakha 93, Giza 168, Sids 12, Misr 1, Gemiza 9 and Gemiza 11) of grain on the germination, seedling vigor, viability and some grain quality parameters from the wheat stored. There was significant increase in moisture content, E.C and acidity percent due to long storage time. Wheat stored in spike form is more resistant than wheat stored in grain form against adverse storage conditions by lower content of moisture, E.C and acidity percentage. The results illustrated that increasing storage period after harvest until 18 months affected significantly all characters. The highest values of germination percentage, seedling vigor, 1000-grain weight, relative density, protein percentage and viability parameters were recorded with wheat stored in spike form. There were highly significant differences among seed quality characters due to storage locations. Sids gave the highest values for germination percentage, seedling vigor, grain viability, 1000-grain weight, relative density and protein percentage compared with Sakha location. On the other hand, results recorded highly significant differences among the tested cultivars for all studied characters which mainly due to differences in the genetic constitution of these cultivars. Misr 1 then Giza 168 gave the highest values of germination percentage and seedling vigor, while Sakha 93 gave the lowest value of germination percentage and seedling vigor
