"The artifact" helps the seed selection of the third generation hybrid rice breeding system

Xinhua News Agency, Changchun, November 24 (Reporter Meng Yanqi) reporters from the Chinese Academy of Sciences Chun Optical Precision Machinery and Physics Research Institute learned that the application of optics National Key Laboratory Associate Researcher Cao Nailiang team and Hunan Hybrid Rice Research Center jointly developed fluorescence detection sub-selector, "the father of hybrid rice" Yuan Longping research and development of the third generation of hybrid rice breeding system seeds for high-precision, large-flux selection, to help Promote the application of china's third generation hybrid rice.
November 2 this year, Yuan Longping led the third generation of hybrid rice has achieved a double-season yield of 1530.76 kg per mu, in order to ensure China's food security to make a new and greater contribution.
but there's a problem behind the promotion. In the third generation hybrid rice breeding process, researchers need to genetically engineered nuclear infertility seed and engineering in the breeding system seeds to maintain a precise distinction between the seeds in the system in order to carry out hybrid breeding. In the past, it was by people holding flashlights, grain by grain to distinguish, a day to distinguish up to a few kilograms of seeds. After two years, the team and Hunan Hybrid Rice Research Center jointly developed the third generation hybrid rice breeding system seed fluorescence detection sub-selector, can accurately select 20 kg of seeds per hour, to solve the bottleneck restricting the promotion and application of third-generation hybrid rice.
The results were approved on November 18 by the Hunan Agricultural Society invited by the expert group on-site acceptance, Chinese Academy of Engineering academician, South China Agricultural University Professor Luo Xiwen and other 9 expert group members said that the technical achievements for the third generation of hybrid rice applications laid a solid foundation, the level of results reached the international leading level of similar research, recommended to accelerate the process of industrialization.
