Winter wheat (Triticum aestivum L.) is the major field crop grown in Latvia. Gluten quantity and quality are important indices for technological processing of wheat. Field experiments with winter wheat cultivars ‘Bussard’ and ‘Zentos’ using four nitrogen top-dressing rates (N60, N90, N120 and N150) were carried out at the Study and Research farm „Peterlauki” of Latvia University of Agriculture in 2009/2010, 2010/2011 and 2011/2012. The objective of this study was to determine year (Y) and nitrogen fertilizer (N) effect for two winter wheat cultivars on wet gluten content and gluten quality. Year, nitrogen fertilizer and year × N-fertilizer interaction had a significant effect on wet gluten content and quality. Significant negative correlation was determined between grain gluten content and gluten index only for cultivar ‘Zentos’ (r = –0.765).
