Plant secondary metabolites are a diverse group of natural compounds. Domestication of modern crops
has lead to their lower diversity and content in modern varieties. Many secondary metabolites have a prominent
effect on human health, both beneficial and detrimental, depending on concentration and preexisting
health conditions. One of the ubiquitous and actively studied group are flavonoids. Since we use many plants,
especially cereals, for food production, it is tempting to create a set of lines with qualitatively and quantitatively
modified content of these compounds. Rye still have high genetic heterogeneity and also high flavonoid
content second only to sorghum. We have analyzed lines from 'Peterhof ' rye genetic collection and found lines
with low flavonoid content as well as lines with high content of peonidin, quercetin, luteolin, syringetin glucosides;
dihydroquercetin, tricetin, chrysoeriol C-glucoside.
