On January 20, at the press conference of the Information Office of the State Council, a reporter proposed that China will expand soybean production in 2022. However, in the main producing areas of soybean and corn, farmers often choose one of the two crops. How to ensure that the corn planting area will not decrease while the soybean area increases. Does the government consider the commercialization of genetically modified corn to solve the corresponding corn supply problem?
In this regard, Zeng Yande, chief agronomist of the Ministry of agriculture and rural areas and director of the development planning department, responded: the pilot of industrialized application of genetically modified varieties in China was carried out in an orderly manner.
In order to solve the problems of Spodoptera exigua and grass damage in current agricultural production, last year, China carried out industrial pilot projects on herbicide resistant transgenic soybeans and insect and herbicide resistant transgenic maize that have obtained production and application safety certificates.
\u3000\u3000 "At present, the progress is relatively good. We speak well. There are at least three points that can be shown: first, the pilot transgenic varieties have excellent characteristics and obvious advantages of cost saving and efficiency increase. The weeding effect of transgenic soybean is more than 95%, which can reduce the weeding cost by 50% and increase the yield by 12%. The control effect of transgenic corn on Spodoptera meadowi can reach 95%, which greatly reduces the cost of insect control. At the same time, transgenic corn seeds The content of mycotoxin in the granules is low and the quality is good. Second, the pilot genetically modified soybean and corn have no adverse impact on the production environment. Planting GM maize reduces pesticide use and promotes biodiversity. Third, we will pilot the implementation of the management of "unified seed supply, unified acquisition and unified technical specifications", regularly carry out patrol guidance, supervision and inspection, and strictly prevent illegal proliferation. " Zeng Yande said.
Zeng Yande emphasized that transgenic breeding is scientific and rigorous. China has established a set of independent R & D system and biosafety guarantee system in the field of agricultural transgenic, and has obtained a number of new lines such as insect resistant and herbicide resistant corn and herbicide resistant soybean with independent intellectual property rights and industrial application prospects. The management of genetically modified varieties is strictly standardized. Agricultural genetically modified organisms can only obtain the safety certificate after passing the scientific and legal evaluation. At the same time, it is necessary to examine and approve varieties and obtain seed production and operation licenses in accordance with the relevant provisions of the seed law before production and planting.
At present, the Ministry of agriculture and rural areas is revising the regulations of four departments, including the measures for the examination and approval of major crop varieties, to clarify the relevant provisions on the industrialized application of genetically modified crops. Zeng Yande disclosed that the Ministry of agriculture and rural areas, together with relevant departments, will continue to steadily and orderly promote the industrialized application of transgenic and other biological breeding and promote the high-quality development of the seed industry based on the principles of respecting science, strict supervision, abiding by laws and regulations and ensuring safety.
