Prospects and results of selection of Fagopyrum esculentum Moench for increased flavonoid content
The paper presents directions and results of breeding work with edible or common buckwheat (Fagopyrum esculentum Moench) in the Far East of Russia on the increased flavonoid content in fruits and above-ground mass. The varieties of F. esculentum of different ecological and geographical origin and breeding material obtained in vitro on a selective medium with a high content of heavy metals were studied on the content of flavonoids and productivity. As a result of the research, indeterminate variety of buckwheat Bashkirskaya red-stem (Republic of Bashkortostan) with the maximum content of flavonoids in fruits (15.0 mg/100 g) and in the above-ground mass (26.6 mg/g) was defined. It is shown that in the selection of buckwheat for a high content of flavonoids in the development of new genotypes, the use of selective media in vitro with high concentrations of copper and zinc ions is of interest. A model of F. esculentum variety with a high content of flavonoids adapted to abiotic and biotic environmental factors in the Russian Far East is presented.
