Abstract This investigation was carried out at laboratories of examination and certification of seeds, at the Agronomy Department, Faculty of Agriculture, Assiut University, Egypt during 2019 season to study the impact of storage period, grains treatment and storage methods on quality and yield traits of Gemaza11 cultivar using completely randomized design. The studied traits, were significantly decreased with increasing storage periods till nine months. The lowest mean value test weight (60), seed index (50.33 g), gluten content (10.33%), fermentation time test (30.67 minutes), fine flour percentage (72%), coarse flour percentage (3.333%), coarse bran percentage (20.33%), and fine bran percentage (4.00%). The highest mean values of grain yield feddan-1. Moreover the lowest mean values of grain yield feddan
