First, Americans took this soybean seed given by China and extracted high-yield genes. And transgenic technology was carried out on seeds, which significantly improved soybean yield and so on. After all this, the United States applied for patents in many countries in the world, including China. With this patent in the United States, we can make hundreds of millions of dollars in profits every year, and even my country has to pay a high price for their genetically modified soybeans.
Second, it is clearly the germplasm resources of China, but it has made a wedding dress for the United States. In fact, there are many such examples. Although a small seed is unremarkable, if it is improved, it can change the fate of a country. On one occasion, in order to let the Syrian state use the seeds they provided, the United States seized Syrian resources, stole grain and set fire to grain fields. However, the seeds given to Syria by the United States for free contain a large number of nematodes. If it is not discovered by the Syrian agricultural department, once it is planted in large quantities, it will bring devastating harm to Syria and even have a huge impact on local agricultural output.
Third, you must have characteristics to be qualified as germplasm resources, which will be collected in China Germplasm Resource Bank. Although there are large areas of cultivated soybeans, the genes of these soybeans are very similar and can even be regarded as clones of a few plants. It can't be called germplasm, so it is difficult to use them to cultivate better soybean varieties. But wild soybeans are different. The genetic diversity of wild soybeans is very similar. Some taste better, some yield higher, some have strong insect resistance, some have good disease resistance, and some have high oil yield. Scientists can use the genetic diversity of wild soybeans to cultivate better soybean varieties.
