Sammendrag

The aim of this study was to investigate variation in protein content and gluten viscoelastic properties in
wheat genotypes grown in two mega-environments of contrasting climates: the southeast of Norway
and Minnesota, USA. Twelve spring wheat varieties, nine from Norway and three HRS from Minnesota,
were grown in field experiments at different locations in Norway and Minnesota during 2009e2011.
The results showed higher protein content but lower TW and TKW when plants were grown in
Minnesota, while the gluten quality measured as Rmax showed large variation between locations in both
mega-environments. On average, Rmax of the samples grown in Minnesota was higher than those grown
in Norway, but some locations in Norway had similar Rmax values to locations in Minnesota. The data
showed inconsistent relationship between the temperature during grain filling and Rmax. Our results
suggest that the weakening effect of low temperatures on gluten reported in this study are caused by
other environmental factors that relate to low temperatures. The variety Berserk showed higher stability in Rmax as it obtained higher values in the environments in Norway that gave very weak gluten for other
varieties.
