Description

Our ancestors had made better use of plant resources. At first, they gathered plants, fruits, shells and some other materials for their foods.Then they settled in the land suitable for farming and started their agricultural life. They cultivated a large number of new crops and some of them are used in our time. Many foreign crops were introduced to Japan and cultivated in many parts of the country. Through the process of cultivation,many local varieties were developed and used for the materials of local foods.Since Mendelian laws were rediscovered,many modern varieties were improved in Japan. In 1970s, overproduction of rice became a social problem. At the same time, small number of newly improved varieties were distributed over a wide area (monoculture) and drove out the local varieties which contributed to the maintenance of a long-established tradition. “ Food culture is supported by agriculture.” So, monoculture in agriculture will be resulted in simplification of our long-established tradition in the future.
