The variety viewing season is coming!
In the Mid-Autumn Festival, the harvest season for corn and rice is also approaching, which is also a good season for variety observation. The performance of varieties this year determines the variety choices of farmers in the coming year. Recently, corn and rice variety observation meetings have been held in Henan, Anhui, Sichuan and other places. -- Editor
This year, the national core exhibition of new corn varieties shows that the on-site observation activities show
Suitable for mechanized grain harvest is the general direction of maize breeding.
On September 8, the 2016 National New Maize Variety Core Show was held in Zhengzhou, Henan Province. In order to promote the popularization of fine new varieties of grain crops, speed up the upgrading of leading varieties and optimize the distribution of varieties, the National Agricultural Technology extension Service Center continued to demonstrate and demonstrate the public welfare of major crop varieties, select excellent varieties of major food crops such as corn, rice and wheat, and set up a demonstration platform for the core display of new national major crop varieties in the northeast, Huang-Huai-Hai and Yangtze River basins. This year, we took the lead in carrying out national corn core display and demonstration activities in Huang-Huai-Hai region.
Dai Jingrui, academician of the Chinese Academy of Engineering and professor of China Agricultural University, Chen Weicheng, professor of Henan Agricultural University, Ding Xinkui, chief economist of Henan Agricultural Department, Ma Yungang, director of Henan seed Management Station, and Ding Wanzhi, director of Maize Professional Committee of National crop Variety approval Committee. A total of 150 well-known corn experts, national corn quality review committee, representatives of relevant provincial seed management stations, national Huang-Huai-Hai summer corn regional test technicians, seed enterprises and breeding units; visited the demonstration base of new corn varieties of Henan Ping an seed Industry Co., Ltd. in Wenxian and the scientific research base of Henan Jinyuan seed Industry Co., Ltd in Xingyang. "Weike 702", "NK718" and other 20 varieties participated in the exhibition.
"the display and demonstration of new crop varieties is the follow-up work of variety test and approval, an important way to publicize and promote the popularization of fine new crop varieties, to speed up the transformation of agricultural scientific and technological achievements, and a strong starting point for agricultural technology popularization." Zhang Yi, director of the Regional Test Office of the National Agricultural Technology extension Service Center, said, "by integrating the resources of all parties, relying on the power of the market, and from the perspective of a third party," Zhang Yi, director of the Regional Test Office of the National Agricultural Technology extension Service Center, said, "to publicize, recommend, follow and evaluate new varieties in various experimental channels, strengthen the publicity and promotion of excellent varieties, and promote the promotion and application of new varieties."
On the afternoon of September 8, the 2016 National Experimental training meeting on varieties in Huang-Huai-Hai Summer Maize region was held, and experts and scholars from the front line of maize seed production explained and reported some of the latest research results to the delegates. Li Shaokun, a researcher at the Institute of Chinese Academy of Agricultural Sciences, put forward some suggestions for close planting and high-yield maize planting by analyzing the changes of maize planting density and yield in various regions of China in recent years, and comparing with the corn planting situation in the United States.
Dai Jingrui evaluated the joint display of new varieties, saying that these exhibitors had done a good job in variety research and development, especially in machine harvesting suitability and lodging resistance, showing the strong scientific research strength of domestic corn seed production. Dai Jingrui said: "from the point of view of demand, corn harvesting machine is more advanced than any other production mode, which has been proved by corn production all over the world." Machine grain harvesting can greatly improve the efficiency of large-scale corn production, although it can not be fully spread out in the Huang-Huai-Hai region in a short period of time, but this is the future direction. "
"in the future, corn breeding will take 'water saving, fertilizer saving and medicine saving' as the core to pursue the sustainable development of ecological and environmental protection." Zhao Jiuran, a researcher and director of the Maize Center of the Beijing Academy of Agricultural and Forestry Sciences, said when reporting on corn engineering breeding, "in order to reduce labor costs, full mechanization will be one of the important directions. In addition, wide adaptability, multi-resistance and efficient use of resources are also important breeding directions, reducing the input costs of agricultural materials such as chemical fertilizer, irrigation and plant protection, and improving market competitiveness by saving costs and increasing efficiency, improving quality and improving efficiency. "
Chen Shaojiang, a professor of China Agricultural University, introduced maize haploid technology, reviewed the development history and application of haploid technology, and thought that haploid technology should be combined with engineering breeding to strengthen technological maturity. Chen Weicheng, a professor at Henan Agricultural University, reviewed the history of the development of maize seed production in Henan Province and China, and suggested that several maize varieties should be subdivided, delineate the core extension areas of each variety, and make variety characteristics.
