Overview:Depends on the corn seed introduced.
Elaboration:Whether a certain kind of corn is genetically modified depends on whether the seeds it introduces are genetically modified, not who planted it, nor where it grows.
If genetically modified seeds are introduced, then this corn will always belong to genetically modified corn, no matter who cultivates it, no matter what kind of soil it grows in, or what kind of climatic conditions it is in, etc.
Conclusion:"Plant melons and get melons, plant beans and get beans". All genetically modified foods come from the seeds that are purchased when they are planted.
-
Whether it is genetically modified corn or not depends on the choice of corn seeds. He's not saying that just because it grows in his own field isn't genetically modified corn. If you're buying genetically modified corn seeds, it's still genetically modified.
-
Whether it is genetically modified corn depends on whether the seeds or seedlings you buy are genetically modified, and whether they grow in your field.
-
Genetically modified corn seeds refer to the seeds cultivated after the corn seeds themselves have been artificially prompted to undergo essential changes, and it is harmful to the body to eat them after they grow into corn, rather than planting corn in their own fields called genetically modified corn, which is a matter of seeds, not fields.
-
Genetically modified corn is different from growing in **, it is related to corn seeds, if the seeds are genetically modified, the long corn is also genetically modified corn, not genetically modified corn seeds, and it cannot produce genetically modified corn.
-
Is the corn grown in your field genetically modified? It depends on the seeds you buy, are they genetically modified? If you buy genetically modified seeds, then the corn in your cornfield is genetically modified.
-
If the seeds of corn are genetically modified, then the corn growing in your own field is also genetically modified, otherwise it is not.
-
Whether it is genetically modified corn or not depends mainly on the seeds. If the seed you choose is genetically modified, even if it is planted in your own field, it is genetically modified.
-
It mainly depends on whether your seeds are genetically modified, and if the seeds are not genetically modified, they are not genetically modified corn.
-
Whether it is genetically modified depends on the seeds, and it has little to do with where they are planted.
-
Is it considered genetically modified corn? This is a question of the variety of corn, and it has nothing to do with what is grown in the field or elsewhere.
-
It depends on whether the corn seeds you buy are genetically modified.
-
It doesn't matter if it's genetically modified or not, it doesn't matter where it grows, the key is that the seed grows is not a genetically modified seed.
-
Is the corn grown in the field genetically modified? It's hard to say, depending on the seeds you buy, is it genetically modified planting? That is, what kind of corn is it, if the seeds bought are genetically modified? The meaning of your own seed ** people as long as they have their own decision.
-
Whether it is genetically modified corn or not does not depend on whose field it grows, but mainly depends on whether the corn seed is genetically modified.
-
Growing there is not the point, the key is whether the seed is genetically modified ......

No. According to the Ministry of Agriculture, the Agricultural Genetically Modified Organism Safety Management Office introduced that at present, after the review of the National Agricultural Genetically Modified Organism Safety Committee, the import safety certificates of four crops of genetically modified cotton, genetically modified soybeans, genetically modified corn and genetically modified rape have been approved. In addition to the approval of the cultivation of genetically modified cotton, the use of imported genetically modified soybeans, genetically modified corn, and genetically modified rapeseed is limited to processing raw materials.
China's laws stipulate that agricultural genetically modified organisms imported for processing shall not be repurposed, that is, they shall not be planted in China. So far, China has not approved the import of any kind of genetically modified grain crop seeds for planting in China. Up to now, China has approved the import of 11 kinds of genetically modified corn as processing raw materials; In 2009, a safety certificate for phytase corn was approved, but it was not allowed to enter commercial cultivation.

Corn is not genetically modified.
The crops approved by China to obtain the safety certificate for the production and application of genetically modified organisms do include corn. However, the special colors on the market, such as purple corn and colored corn, are the result of conventional breeding, not genetically modified varieties. Pocket Jane Peizhen corn and small corn are actually corn that has not yet grown and matured, and is also known as "corn shoot dust" or "baby corn" in China, and has nothing to do with genetically modified organisms.
Similarly, there are small pumpkins and gherkins.
Genetically modified technology refers to the use of DNA recombination, transformation and other technologies to transfer specific exogenous target genes into recipient organisms, and make them produce predictable and directed genetic changes. Genetically modified technology is a core component of modern agricultural biotechnology. Compared with traditional technology, genetically modified crops are more beneficial to farmers and more environmentally friendly.
Genetically modified crops have two important advantages, one is a lower need for pesticides, and the other is more tolerant to herbicides.
A series of genetic research work has opened a new era of human modification of organisms, and this kind of technical system that uses modern biotechnology means to achieve the desired goal according to the principle of engineering design is called "genetic engineering" or "genetic engineering". Plant genetic engineering is often referred to as "genetically modified technology", and the resulting product is referred to as a genetically modified plant or genetically modified crop, and sometimes by names such as "genetically modified organisms" or "engineered crops".
Genetic mutations occur every day in nature, and the probability of mutations that may be brought about by transgenesis is even greater. Transgenic genes have been artificially selected for superior genes and excellent traits have been clustered across species. It breaks the barrier of species, expands the available genetic resources, improves the efficiency of selection, and makes the breeding process more efficient.

Hello, dear, the method of judging whether corn is genetically modified: 1. First of all, you can distinguish from the size. If the corn is too large and the yield is high, most of it is genetically modified corn.
The corn is small, and the size of the corn kernels varies. 2. Look at the color, secondly, you can distinguish it from the color aspect. The color of ordinary corn is relatively uniform, if it is colored corn, most of the purple, white and yellow corn kernels are genetically modified corn.
3. Look at the season and pay attention to the corn production season. If it is out of season, most of them are genetically modified corn, and ordinary corn has a fixed harvest time. It is usually in May and October every year.
4. Look at pests for reference from the pest's point of view. Most pests will prefer to patronize Puxiao Sleepy Corn, while genetically modified corn is rarely attacked by pests. Sincerely hope to help you, I wish you a happy life!
If you find it helpful to you, please give it a thumbs up, thank you! <>

Previously, Shi Yanquan, deputy director of the Department of Science and Education of the Ministry of Agriculture, said in a guest on China's "China Interview" that there is no domestic genetically modified rice and corn on the market.
Shi Yanquan said that there are two situations of genetically modified products approved in China, one is for commercial production of genetically modified edible crops, while genetically modified rice and transgenic phytase corn need to be approved by the variety, and almost no circulation in the market.
Another situation is that China is used to import and process raw materials of genetically modified agricultural products, including soybeans, corn, rape, they will enter the production process, the most is genetically modified soybeans, at present, China issued a total of 5 genetically modified soybean varieties and 13 genetically modified corn varieties import safety certificates, approved application and imported genetically modified organisms are strictly evaluated in terms of environmental safety and food safety. The safety evaluation shows that these GMOs and non-GMOs that are approved for application and import have the same safety and can be eaten with confidence.
Therefore, there is no genetically modified corn in the Chinese market, but there are processed foods produced from genetically modified corn as raw materials into the market, which can be purchased and eaten with confidence.

There is no difference, except that the genetically modified organisms grow faster. Genetically modified corn varieties refer to new corn varieties cultivated by genetically modified technology.
Extended content: Transgenic breeding is to transfer specific genes of one organism to another organism according to a pre-designed blueprint with the help of laboratory operation techniques, so that the latter can obtain new genetic traits in a targeted manner. That is, the introduction of useful plant genes (such as potatoes) into the genetic material of corn that needs to be improved, and the offspring of corn with stable genetic traits that people are looking for.
Before the genetically modified varieties are approved for use, they must also pass the national safety evaluation of the genetically modified varieties. China has not yet approved genetically modified corn for commercial production.

There are several points to distinguish between maize genetically modified and non-genetically modified:
Genetically modified corn: sweet and crunchy, plump, beautiful in shape, with similar heads and tails.
Criteria for judging genetically modified foods.
1. Season. In addition to greenhouse vegetables, other out-of-season foods are prone to be genetically modified.
2. Color. Different from the traditional ones are genetically modified, such as colored cotton and colored peppers.
3. Size. Traditionally, tomatoes also have a certain size, for example: a small tomato as big as a thumb is genetically modified.
Another example is soybeans, also called soybeans, which are made of tofu, the kind of beans made of soy milk, which should be shaped like animal offal: the waist looks like a little flat, but the current soybeans are all round, much larger, and pea-like soybeans, with a high yield, which is genetically modified.
4. Taste. Traditional corn is generally yellow corn, white corn, slightly sweet, and now popular sweet corn, its sweetness is very high, undoubtedly genetically modified.
5. Pests. All crops that pests like to patronize are not genetically modified, and all crops that pests are afraid of, that is, there are no pests, or few pests, are genetically modified.
6. Output. Genetically modified crops are generally produced much higher than conventional crops in the first few years.

1. Corn grains: The size of normal corn kernels is not the same, but the grain size of genetically modified corn is very uniform.
2. The color of corn: corn is often golden yellow, and now there are colored corn, as well as black corn, and most colored corn is genetically modified corn.
3. The size of the corn: If the corn you see is relatively normal in appearance, the moderate size is the corn that is traditionally planted. But if the corn you see is different from normal corn and is extraordinarily large, it is genetically modified corn.
The role of corn.
It should be noted that although corn is rich in corn oil, it is almost linoleic acid, so eating corn and corn oil can play a better role in reducing fat, and a large amount of unsaturated fatty acids contained in corn also have the effect of reducing greasy. Thus enhancing physical fitness.
It should be noted that the flavonoids contained in corn have a good relieving effect on the retinal macula of the human body. Especially for office workers who often face the screen and use their eyes, eat a stick of corn every day. Maybe the eyes will become brighter than before.
The above content refers to Encyclopedia - Corn.
People's Daily Online - Experts say that the current international corn market is basically genetically modified corn.
