The antioxidant activity of investigated genotypes determined by the DPPH (2.2-diphenyl-1-picrylhydrazyl) method (FRSA) varied from 4.68 to 10.38 mg TE/g (Trolox equivalent), molybdenum-reducing power of extracts detected by the phosphomolybdenum method (MRP) and was from 41.43 to 209.93 mg TE/g depending on genotype.
