According to statistics, by the beginning of 1999, the U.S. Department of Agriculture has been approved for the production of genetically modified crops have seven categories of 35 kinds, including five kinds of late maturing tomatoes, herbicide-resistant soybean 2 kinds of increase in the lauric acid fat of canola 1 kinds of insect-resistant potatoes 2 kinds of insect-resistant and herbicide-resistant maize 6 kinds of disease-resistant papayas 2 kinds. These two types of papaya alone saved the U.S. Hawaiian papaya industry. China has approved the commercial production of four products, including "8805R", a cucumber mosaic virus (CMV)-resistant tomato bred by Peking University, and "Shuangfeng R", a CMV-resistant bell pepper.

Expanded Information:

One type of biotechnology that developed rapidly in the 1980s was the breeding of new varieties by means of genetic modification. The main technique is to obtain DNA fragments with specific good genetic traits, i.e., target genes, from the target donor species, and introduce them into the embryos of the modified species, i.e., the "recipient species," either directly or through carriers, to cultivate good new varieties.

As of 2013, transgenic rabbits, pigs, and chickens with fast growth rates, strong disease resistance, and good meat quality have been introduced. Liang Liqun and other cloned son of cannabis fish growth hormone gene, in vitro and carp MT promoter gene recombination, imported into the Heilongjiang wild carp, selection and breeding of "super carp". In addition, some people will vaccine gene transfer into the mammary glands of sheep, so that these products are secreted with the milk, than with the production of engineered Yin production costs are lower and more productive.
