Scholars still disagree about the origin of radish. De Candole (1886) thinks that radish originated in West Asia and spread to all countries in the world. According to vavilov (нивавилов,1923-1), Darlington (65438. Now most scholars believe that the original species of radish originated from radish on the warm coast of Europe and South Asia. Bailey (1923) thinks that China and Japanese radishes evolved from radishes originating in China. European radishes evolved from radishes along the coast of China. According to documents, radish was planted in ancient Egypt 4500 years ago. China has a long history of growing radishes. In Erya Cao Shi (BC 1 century), it was pointed out that "radish with purple flowers is called turnip", and the cultivation method of radish was already recorded in Qi Yao Min Shu (AD 630) written by the Four Associations. In the Tang Dynasty (1950s), Su Gong's Herbal Medicine recorded the pungent, sweet, warm and non-toxic properties of radish, as well as the medicinal value of eliminating grain, reducing qi and resolving phlegm. In the Song Dynasty, Su Song wrote "Illustration of Materia Medica" (106 1), saying: "Laiqu is connected with the north and the south, and the north is rich in soil", which shows that radish cultivation in China was more common in the Song Dynasty. Li Shizhen's Compendium of Materia Medica in Ming Dynasty (1578) said that radish had become a popular vegetable in China at that time. It should be noted that there are records about wild radish in China in the Ming Dynasty. Xu Guangqi (1628) once described "wild radish, born on land, is not radish. If it is radish, it is not difficult to cook and easy to cook, and hunger can beat meat." But in modern times, there is no further report about wild radish in China, and it may have disappeared in the process of evolution, but it does not rule out the possibility of being discovered.

There is no textual research on the origin of China radish in history. In recent years, Chinese scholar Zhou Changjiu (199 1) used the methods of plant geography, ecology and esterase isozyme analysis, according to vavilov's "distribution".
