Winter wheat (Triticum aestivum L.) is a major field crop in Latvia. Gluten quantity and quality are important indices for technological processing of wheat. The research was carried out at Latvia University of Agriculture Study and Research farm „Peterlauki” in 2009/2010, 2010/2011 and 2011/2012. The objective of this study was to determine the effect of nitrogen fertilizer (N60–N150) on two winter wheat cultivars ‘Bussard’ and ‘Zentos’ on wet gluten and gluten quality on fully ripe and stored winter wheat grains. The grain of cultivar ‘Bussard’ had significantly higher wet gluten content and quality, if compared to ‘Zentos’(t-test). For the grain stored for 60 – 360 days, the content of wet gluten declined and the quality of gluten improved. Data averaged over three years show strong negative correlation between gluten index and wet gluten content for both cultivars (r= -0.644 for ‘Zentos’ and r= -0.444 for ‘Bussard’; p is less than 0.01).
