Development of purple-grain triticale

Abstract

Purple-colored grains of cereal crops are characterized by high antioxidant activity. Anthocyanins, polyphenolic compounds found in the pericarp of their grains, have beneficial effects on human health. However, triticale has not yet developed forms with anthocyanin-rich purple grain color. The aim of this work was to obtain new forms of wheat-rye amphiploids with purple grain color using marker-assisted breeding and to compare their anthocyanin content and productivity indicators. Molecular DNA markers were used to determine the genotype of hybrids produced by triticale Sadko (× Triticosecale Wittmack) and a purple-colored emmer wheat line 27-3/17 (T. dicoccum (Schrank) Schuebl.). Purple-colored F3 hybrids carried two complementary dominant genes Pp3 and Pp-B1 in a homozygous state respon
