Modern Molecular breeding Technology: successful Development of Soybean Molecular breeding Technology in South Korea
Korea Rural Revitalization Agency Agricultural Life and Engineering Research Institute recently successfully developed a soybean molecular breeding technology, which means that South Korea's mass production of organic soybeans containing anti-cancer ingredients will become a reality.
South Korea through tissue culture soybean plant redifferentiation technology is not very developed, so the conversion of soybean is mainly imported from the United States. The Rural Zhenxing Department revealed that molecular breeding technology is known as the third generation genetic engineering technology, and using this technology, higher value-added soybeans can be produced, which is of great significance in increasing farmers' income.
Molecular breeding method, also known as genetic engineering breeding method, is to recombine exotic (extracted from other organisms) or synthetic DNA (or RNA) fragments artificially at the molecular level, and then introduce them into the cells of "recipient" organisms through certain vectors and combine with the original DNA to make offspring "express" the genetic traits controlled by the newly introduced genetic information carried by DNA (or RNA). Thus the modern breeding methods of new varieties (or new species) can be created quickly, stably and directionally. The difference between it and general breeding is that it breaks through the boundary of "species", thus greatly expands the scope of gene communication, and is the specific application of the theoretical and technical achievements of molecular genetics in breeding.
This "new process", also known as "gene transfer" and "gene grafting", enables people to transform or reconstruct biological heredity, just as accurately as engineers carry out construction according to a pre-designed blueprint, creating new varieties or species that cannot be created by general breeding methods. Molecular breeding method will revolutionize breeding technology and enter a new stage with more precision and stronger purpose, showing an attractive prospect.

8 attention to the purchase of improved soybean varieties
1. Pay attention to the purity and germination rate of seeds. 2. Pay attention to whether you are committed to free consultation and technical guidance. 3. Pay attention to whether the points are set at random. 4, mail order seeds, pay attention to the local post office remittance, do not put the money in the letter. To write down your detailed address and name, indicate the variety and quantity purchased in the postscript column. 5. Pay attention to the correct trademark and packaging mark. 6. Pay attention to agree on the seed price. 7. Pay attention to whether you are responsible for seed quality. 8. Pay attention to contact by telephone or letter before introduction, or consult the relevant units.
