Abstract:

Soybean is one of the most important agricultural products that are closely related to people's life and economic and social development. At present, the improvement of soybean production level and increasing soybean self-sufficiency rate are major problems that must be solved in China's agricultural development. Due to the shortage of cultivated land resources in China, scientific and technological innovation is the only way to improve soybean production capacity. Transgenic breeding is a key technology to promote the development of soybean production, and it has played an important role in the development of soybean industry in the world's major producers such as the United States, Brazil and Argentina. In last 20 years, the breeding techniques of herbicide-tolerant and insect-resistant soybean have obtained a great progress and some products can be used for commercialization in China. And the commercial planting of transgenic soybeans can significantly reduce productive cost and raise soybean yield. Based on the developmental progress of transgenic soybean techniques and the characteristics of soybean production in China, the following strategy is suggested to boost the commercialization scientifically and orderly. Firstly, in terms of product application, based on the single trait product for glyphosate tolerance, and the products with multiple genes for two or more herbicide tolerant traits such as glyphosate and glufosinate tolerance, as well as for stacking of herbicide tolerance and insect resistance traits, the commercialization of the above seeds should be conducted in order. Secondly, in terms of product regional layout, based on occurrence and regional distribution characteristics of target weeds and pests, top-level design of growing zones to herbicide-tolerant and insect-resistant soybean products should be performed. Thirdly, in terms of biosafety management, population monitoring and management techniques for resistant weeds and pests should be developed to extend service period of genetically modified products. In the meantime, the conservation of wild soybean germplasm resources should be strengthened to reduce the negative impact on biodiversity of wild soybean caused by gene flow from transgenic soybean in natural eco-system.
