1 Chinese buckwheat breeding status 1.1 The status of buckwheat resources and distribution buckwheat Polygonaceae (Polygonaceae) Fagopyrum (FagypyrumGaerth). China is one of the main producing areas of buckwheat in the world and is also the origin center and the center of genetic diversity of buckwheat in the world. There are 15 species and 2 varieties of buckwheat currently found in the world, of which there are 10 species and 2 varieties in our country. Buckwheat cultivars are common buckwheat (Common Buckwheat) and tartary buckwheat (Tartary Buckwheat) two species, are planted in our country. In the past 20 years, China has made remarkable achievements in the research of buckwheat resources. After extensive collection, cultivation, identification, analysis and inventory in 24 national germplasm resources banks in China, there are 2 785
