Abstract: The aim of the study was to evaluate total antioxidant activity (TAA) and total content of carotenoids (TCC), anthocyanins (TAC), phenolics (TPC) and phenolic acids (PAs) in grain of selected pigmented wheat genotypes and traditional control cultivar cultivated under organic and conventional cropping systems in two-year trials. All of the evaluated parameters were significantly affected both by genotype and evaluated environmental factors. While in TPC, PAs and TCC the effect of years prevailed, TAC was affected mainly by genotype. The effect of genotype and year in TAA was comparable. TPC ranged from 581.71 mg/kg (control cv. Annie) to 723.60 mg/kg (cultivar with purple pericarp PS Karkulka), total PAs content from 711.77 mg/kg (cv. PS Karkulka) to 849.47 mg/kg (cv. Skorpion with blue aleurone). TCC varied from 1.56 mg/kg (cv. PS Karkulka) to 5.32 mg/kg (cv. Citrus with yellow endosperm). The highest TAC (63.23 mg/kg) was found in cv. Skorpion, the lowest (12.70 mg/kg) in cv. AF Jumiko with purple pericarp. Anthocyanins were not detected in cvs. Annie and Citrus. TAA varied from 162.68 mg/kg in cv. Annie to 226.71 mg/kg in breeding line KM 53-14 with blue aleurone. Higher TAA and antioxidants contents and lower grain yields were observed in organic cropping system and in drier year 2016.
