Abstract
In order to illustrate the importance of studying sowing dates of some wheat cultivars, a field experiment was  carried out at Sakha Agri. Res. Stat. ARC at the north region of Delta Egypt during the two winter successive seasons 2015/16 and 2016/17. Six Sowing date were i.e 15th October, 1st November, 15th November, 30st November, 15th December and 30st December. Four bread wheat cultivars,  Gemmeiza 11, Giza 168, Misr 1and Misr 2. The obtained results could be summarized as; The fourth  sowing date (30st November) gave the highest values of most studied characters under this investigation such all agronomic traits, globuline content (non-glotein protein), gliadine content (gluten protein ), followed by third sowing date (15th November). Such glotenine content (gluten protein). On the other hand, the first sowing date (15th October) gave the highest values of albuimine content (non-glutein protein). Sowing on third (15th November) and fourth sowing date (30st November) gave the highest value of germination and storability (accelerated aging germination). The sixth sowing (30st Decmber) gave the highest values of grain crude protein, soluble and non-soluble protein. There were significant differences among wheat cultivars in all agronomic studied were observed. Gemmeiza 11 recorded the highest number of tillers/m2, 1000 grain weight, grain yield, harvest index, glotenine content (gluten protein ), wet and dry gluten and soluble protein content. Meanwhile, Misr 1 and Misr2 cultivars recorded the highest values of globuline (non- gluten protein), gliadine content, glotenine content (gluten protein), germination% and storability (accelerated aging germination). On the other hand, G.168 cultivar recorded the lowest value of gliadine and glotenine content (gluten protein), while gave the highest value of albuimine content (non-gluten protein). Gemmeiza 11 superior the other cultivars for grain yield and Giza 168 superior the other cultivars straw yield in 2015/2016 and 2016/2017.
