New varieties of high quality protein maize in China rank the world's leading level

Introduction: new page 1 the Zhongdan 9409 high quality protein corn variety jointly cultivated by Hebei Wanquan seed company and Chinese Academy of Agricultural Sciences is famous for its good quality, high yield and rich nutrition Dr Norman brauger, a world-famous seedling expert and Nobel laureate, believes that this scientific research achievement is at the leading level in the world, and predicts that the promotion and utilization of this scientific research achievement will play a greater role in solving the global food problem than the green revolution in promoting Mexican wheat in that year It is understood that high-quality protein maize can improve the quality of embryo floating protein by introducing opak-2 gene to improve the content of lysine and tryptophan in the protein The content of lysine and tryptophan in high quality protein maize is about twice as high as that in common maize, and the yield increase is 8% - 15% Industry insiders believe that the successful cultivation of this variety is not only a revolution in planting, but also has a positive and far-reaching impact on animal husbandry and food processing industry Wanquan seed company combines its own economic advantages with the talents and technical advantages of Chinese Academy of Agricultural Sciences It has invested more than 5 million yuan in scientific research and development, and developed more than 10 high-quality protein varieties including Zhongdan 9409 At the same time, according to the characteristics of different ecological regions, an experimental base network consisting of 36 backbone points and 41 auxiliary points was established in China Up to now, high-quality protein corn varieties have been popularized in 58 counties of 11 provinces and cities, including Henan, Shaanxi and Shandong, with planting area of more than 300000 mu Wanquan county has become the national high-quality corn seed production base, and has been listed in the national seed engineering project and the national harvest plan EBr
