Corn is an annual monoecious cross-pollinated plant with tall plants and stout stems. It is an important food crop and feed crop, and its total output ranks first in the world. Its planting area and total output are second only to rice and wheat.

Known as longevity food, corn is rich in egg white, fat, vitamins, trace elements and cellulose. It has great potential to develop foods with high nutrition and high biological function.

However, due to its complex heredity and rich variation types, there are some shortcomings in the conventional breeding process, such as too long cycle and too large variation coefficient, which affect the growth and development of future generations. Modern biological breeding technology not only overcomes the above shortcomings and deficiencies, but also improves the breeding speed and quality.

History and culture

There is a saying that European civilization is wheat civilization, Asia is rice civilization and Latin America is corn civilization. Mexico and Central America are the cradles of corn. According to archaeological findings, there was wild corn here as early as 1 10,000 years ago, and the history of planting corn in India has been 3,500 years.

Archaeologists discovered the remains of corn culture from 7000 BC to 1540 AD in Tevacan Valley of Puebla, which shows how ancient Indians gradually began to pick wild fruits and transitioned to artificial corn cultivation when hunting activities became scarce.

The long history of corn culture has enabled Mexicans to temper their corn planting and processing technology to the extreme.

In Mexico, there are not only white corn and yellow corn, but also dark blue corn, dark green corn and purple corn, as well as colored corn mixed with red, blue, green, white and yellow. Mexicans make a wide variety of corn foods, and there are new creations.
