Rye is a cereal traditional for Northern and Eastern Europe with
very good resistance to abiotic stresses and ability to grow on
poor soils. Because of relatively recent domestication and obli-
gate cross-pollination rye still possesses a great diversity of gene
variations leading to variations in content of secondary metabo-
lites. In our study we evaluated anthocyanins and flavonoids con-
tent in grains of 24 rye forms and inbred lines (Peterhof
collection of rye) by HPLC-ESI-MS.
