BACKGROUND: The current study aimed to estimate the effects of organic and conventional production systems and four winter wheat ( Triticum aestivum L.) bread cultivars on the technological properties of grain, flour, dough and bread, to increase current knowledge regarding the interactions of the technological properties of winter wheat and assess the cultivars for their suitability for organic production systems. RESULTS: All the technological properties winter wheat which were investigated were significantly affected by the agricultural production system and cultivars, and some of them, mostly grain quality parameters, by the harvest year. Grain from organic winter wheat had significantly lower protein and gluten contents, lower sedimentation and flour water absorption values, shorter dough stability time and lower loaf volume, but higher values of starch content and stronger gluten, compared with grain from the conventional wheat. For both production systems significant positive correlations of protein content with gluten content, sedimentation value, dough stability time, loaf volume, farinograph water absorption, and negative with starch content, gluten index were determined. CONCLUSIONS: Statistically significant differences between agricultural production systems were found. The cultivars Ada and Alma had better technological properties that make them more suitable for the organic production system, compared to Širvinta 1 and Zentos.
