The main direction of selection work with buckwheat in a forest-steppe zone of Krasnoyarsk Region has to aimed at receiving varieties steady for local conditions of vegetation requiring the creation of selection material with high contents of routine which is responsible for adaptation of plants to adverse conditions of growth. The research objective was the creation of selection material with high routine contents. The results of re-search of routine contents in vegetable raw materials of six samples of buckwheat are presented: Dikul (All-Russia Research and Development Institute of Legumi-nous and Cereal Cultures. Oryol); Zemlyachka (Bashkir Research and Development Institute of Agriculture, Ufa); local selection hybrids: 1; 2; 3; 4. At the assess-ment of analyzed vegetable samples the method using chloride of aluminum forming complexes with flavonoids was chosen. The calculation was carried out by the method of calibration schedule, as standard sample routines were used. The maintenance of flavonoids was measured in two series of analyzed solutions: with alu-minum chloride (experiment) and without it (standard), i.e. was applied differential option which allowed exclud-ing the influence of other substances on the results of the analysis. The phase of selection of vegetable tests was mass blossoming of buckwheat. By the results of the research routine contents in the models of local se-lection (2, 3), in comparison with buckwheat varieties cultivated in the region Dikul and Zemlyachka. Selection material with routine higher contents, than in the varie-ties cultivated in production, for the purpose of creation of mid-season variety of buckwheat for forest-steppe zone of Krasnoyarsk Region was found out.
