Variation in gluten quality parameters of spring wheat varieties of different origin grown in contrasting environments

Abstract

a b s t r a c tThe 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.

The influence of production technology on yield and selected quality parameters of spring wheat cultivars

“…In the case of this cultivar, in 2016, intensification of the cultivation process significantly decreased the activity of amylolitic enzymes. In the previous studies (Cacak-Pietrzak & Sułek, 2007), the intensity of production technology did not have a significant impact on this characteristic of the grain, but, similarly as in the studies of Uhlen & et al (2015), it depended on the cultivar.…”

“…'Arabella' ( Table 3). The influence of the cultivar features on the protein content in spring grains of wheat cultivars was also demonstrated by Uhlen et al (2015). In 2015, the total protein content of grains was on average by 0.6 percentage points higher than in 2016, due to the weather conditions more favorable for the accumulation of protein.…”

Genome mapping of seed-borne allergens and immunoresponsive proteins in wheat

“…The effect of low- and high-temperature environment stress on seed protein composition of Bjarne and Berserk was previously studied by Uhlen et al . ( 33 ). Differences in grain weight, protein content, and dough quality parameters between the two environments studied were related to temperature.…”

“…The environmental factors at the harvest time affect the quality of flour. However, there is a great variation of results presented in these studies (Finlay et al, 2007;Uhlen et al, 2015). On the other hand, Georget et al (2008) did not find differences between the proportion of HMW proteins when wheat breeding lines were evaluated in different environments but did not find differences when the interaction between the environment and genotype was assessed.…”
