Oats is a cereal crop belonging to Genus Avena of the family of Gramineae with the Latin name as Avena sativa L., which is a rare health care product in cereal crops. Oats are widely distributed, but there is still no consensus on the origin of oat species. Currently, there are four centers of oat origin, namely the Mediterranean coast, the Iranian plateau, Africa and western China. About 30 species of oats have been discovered and identified. After more than 300 years of development, its taxonomy has developed a set of recognized classification methods based on the number of chromosomes, namely, Baum's oat classification system, which is the basis of today's oat classification. Oats, like the other cereal crops, are divided into diploid oats, tetraploid oats, and hexaploid oats, but the evolution of oat chromosomes remains controversial. The authors attempt to provide a comprehensive overview of the classification, origin, and evolution of oats since its establishment in 1700.
