Rice, wheat, corn, and potatoes are four crops that provide a daily source of nutrition for humans, but there are many problems that have been found with these crops. First, they lack amino acids and minerals which are necessary for balanced nutrition, and they also are grown very widely and as monocultures, which increases the risk of the human food system being destroyed by climate change. Thus, by introducing coarse cereals with good characteristics, we can enrich human food resources, realize agricultural diversifica-tion, improve dietary structure, and mitigate risks. Tartary buckwheat (Fagopyrum tataricum) is a widely cultivated edible and medicinal crop with unique nutritional and excellent economic value.
