Abstract:

China has more population in the world but with limited arable land and water resources. Scientific innovation becomes a unique solution to promote the crop productions for national food security. Commercialization of biotech breeding technology in maize， soybean， oil rape and cotton has played a critical role in seed industry developmentin these major crop production countries including US， Brazil and Argentina. After over 20 years’ scientific innovation of biotech crop research and development （R&D） in China， the biotechnology crops for maize and soybean with resistance to insect and herbicide tolerant traits have been ready， these biotech crops would not only reduce the inputs of crop production， but also increase the yield and farmers’ incomes significantly. Due to the commercialization of biotech breeding technology involves in multiple aspects of research and development of scientific innovation， regulatory appraisal of biosafety and stewardship requirements， international trade， agricultural production and public acceptance etc.， which is a large and complex system engineer. Therefore， only those of the larger seed enterprises with capabilities can lead the whole processes by integrating R&D resources of scientific， academic and seed industrial units to create an innovation consortium for collaborations across the whole R&D chain and commercial chain together. Such an innovation consortium will be capable to continuously launch new varieties with better-yielding， nutritious， less inputs and environmental-friendly products should steadily support the commercialization of biotech breeding technology of important crops towards a sustainable and high-quality development of seed industry in China. Biotech breeding technology is the core of seed innovation， so establishing an innovative system for modern breeding and strengthening the deep mine of germplasm resources plus breaking through the key technologies of cutting-edge breeding for strategic new varieties， becomes the solution for germplasm improvement and a key for winning the seed industry as well as the fundamental support for firmly grasping the initiative of food security. This paper summarized the application of biotech breeding， and proposed the developmental strategies of modern seed industry. Biotech breeding technology will become the important approach to solve the germplasm resource shortage and environmental constrains faced by China’s agricultural development while driving the development of China’s modern seed industry and the continuous improvement of international competitiveness， and realizing the leap from a large seed industry to a strong seed country.
