Talking about "genetically modified" discoloration seems to have become a daily idea, so we avoid many delicious foods, such as brightly colored peppers, seedless grapes, rows of corn ... In the face of genetically modified foods, we seem to overdo it and believe rumors more easily.

Autumn is coming, and it's corn season again. I remember when I was a child, I came home from school clamoring for corn on the cob. I thought corncob was delicious at that time. Recently, however, a news spread on the Internet: 12 row of corn is not genetically modified, and more than 12 row is genetically modified. (Note: the bottom line is 12, which is not genetically modified; The middle row is 14, and the top row is 16, all of which are genetically modified. )

Different corn has different rows and networks.

So, what does this 12 row mean? What does it have to do with genetic modification? Will we really eat genetically modified corn? Next we will answer them one by one.

The 12 line you said is called the number of lines per ear.

First of all, the rumored lines "12, 14 and 16" have a corresponding proper noun-"rows per ear" in maize biology. Since 1996, nearly 40 billion mu of transgenic crops have been planted in the world, but most of them are insect-resistant or herbicide-resistant genes, and there are a few genes related to cold resistance and drought resistance such as quality improvement (such as golden rice).

Therefore, rows per ear is an important index of maize yield traits, but it is by no means an index to judge whether a maize is genetically modified. At present, the commercial planting of genetically modified corn abroad can not be accurately judged by naked eyes, and can only be realized by molecular detection. There is no commercial cultivation of genetically modified corn in China.
