Renewed interest in breeding for high anthocyanins in wheat (Triticum ssp.) is due to their antioxidant potential. A collection of different pigmented wheats was used to investigate the stability of anthocyanins over three crop years. The data show higher anthocyanins in blue-aleurone bread wheat (Triticum aestivum L.), followed by purple- and red-pericarp durum wheat (Triticum turgidum L. ssp. turgidum convar. durum), using cyanidin 3-O-glucoside as standard. HPLC of the anthocyanin components shows five to eight major anthocyanins for blue wheat extracts, compared to three anthocyanins for purple and red wheats. Delphinidin 3-O-rutinoside, delphinidin 3-O-glucoside, and malvidin 3-O-glucoside are predominant in blue wheat, with cyanidin 3-O-glucoside, peonidin 3-O-galactoside, and malvidin 3-O-glucoside in purple wheat. Of the total anthocyanins, 40− 70% remain to be structurally identified. The findings confirm the high heritability for anthocyanins, with small genotype × year effects, which will be useful for breeding purposes, to improve the antioxidant potential of cereal-based foods.
