Variation of Flavonoid Content in Tartary Buckwheat Seeds from Different Areas

Thirty-five kinds of tartary buckwheat from different areas were used as experimental material and the flavonoid content of their seeds was determined and compared under the same cultivation conditions.The result showed that the flavonoid content of 35 kinds of tartary buckwheat ranged from 2.19% to 4.02% with an average of 3.12%.There was difference among tartary buckwheat from different areas.The seeds from Liupanshui of Guizhou had the highest content of flavonoid,while the seeds from Shaanxi had the lowest content of flavonoid,which was 2.90%,respectively.The order of flavonoid content was SichuanGuizhouYunnanGansuShaanxi.The study clarified the genetic variation law of flavonoid content among different tartary buckwheat resources.
