Bread-Making Potential and Yielding of Hybrid Wheat Under Varied Agronomic and Environmental Factors


The purpose of this study was to determine the effect of simplified tillage systems (RT, NT) in comparison with conventional tillage (CT) on technological grain quality and baking value, as well as of hybrid wheat grown under variable weather conditions. A three-year field trial experiment was conducted using a randomised block design, in triplicate. The factors studied were as follows: I - three tillage systems - no-tillage (NT), reduced (RT), and conventional (CT); II - two winter wheat cultivars ‘Hylux’ (cv. hybrid) and for comparison ‘Bogatka’ (cv. common). The use of CT and RT tillage systems compared to NT significantly increased yield by 8.9 and 7.7%, respectively, and selected grain quality parameters along with a more favorable gluten protein profile. The flour obtained, with water absorption above 58.0%, can be classified as strong flour with good farinographic and alveograph parameters. The genetic characteristics of the wheat cultivars determined the technological quality of the grain and the baking value, as well as the grain yield. For ‘Hylux’ cv. hybrid wheat, there was a higher yield and better grain quality, which contained significantly more gliadins and glutenins, and the flour was characterised by higher parameters that determine the preferred viscoelastic properties of the dough. The common ‘Bogatka’ wheat cv. accumulated higher contents of ω gliadins and LMW and HMW glutenin subunits in the grain, while for α/β and γ gliadin contents the difference was not significant. A fairly dry period (June–July) of wheat ripening reduced the grain yield but was favourable for higher values of quality characteristics, gluten protein fractions, as well as the farinographic (WAF, DDT, DS) and alveograph (W, P, L) parameters.
